Has anyone else seen a regression in bootstrap compilation speed?

I am currently building Emacs-28 trunk. I am still on the 
bootstrap-emacs phase after half an hour or so and am getting no more 
than 2 or 3 ELC+ELN steps complete per minute, with a parallel build.

I haven't been doing bootstrap builds consistently, so I do not know if 
this has changed recently or whether I am just seeing it for the first 
time, so this is not a very consistent "bug report", rather just to see 
if anyone else is seeing something similar.

Phil

How many parallel jobs did you allow Make to have?  And on what OS is
this?

Also, do you see this slow compilation only for the first few files,
before comp.el is natively-compiled, or even after that?

Ubuntu 20.04. I tried both single threaded (so I could see how long 
individual files take) and my normal build (-j 20). Again, based on my 
ad hoc experience rather than any careful measurement, it was for all 
the elc+eln using bootstrap-emacs. Once emacs proper was generated, 
things went rather more quickly and upto my expectations.

It's probably something local to me. I thought to mention it here 
because I think we still do not have good metrics set up for bootstrap 
build speed performance.

With "make -j4" recompiling natively all the preloaded files and their
dependencies on the emacs-28 branch, I see this:

  . compiling the 16 COMPILE_FIRST files takes 22 min, with comp.el
    being the worst offender: about 20 minutes
  . compiling all the rest of the preloaded files takes an additional
    25 minutes

If someone can compare this with past versions, maybe we could see if
the slowdown is real.

Thanks.

No, I am afraid not.

The performance that I got on Windows builds when I did do it was highly 
variable (between half an hour and three), but I think this was mostly 
the shared CPU infrastructure I was using. I never worked out how to get 
native comp working in a way that I could package it for windows, so the 
builds were all without it.

Okay, that's similar to what I am seeing.

I can probably do a little testing over the weekend (while my computer 
is otherwise inactive) to see if it has slowed down.

This is my present situation also.  I can build with native comp but not
(yet) found a way to package that version.

I don't understand yet the packaging requirements, is it not possible to
copy additionally the native-lisp/ folder to the package?

So far I could compile (locally) the current pretest 28.0.91 version
--with-native-compilation.

Then I tried to build (with build.zips.sh) a snapshot of the
masterbranch --with-native-compilation on the same system.  And now
./configure is complaining:

  configure: error: Elisp native compiler was requested, but libgccjit was not found.

Does Emacs-29 has different requirements?

I'm not familiar with that script, so I don't think I understand the
implications.

Sorry, I meant the script admin/nt/dist-build/build-zips.sh

   $ build-zips.sh -s

The problem is that native comp needs libgccjit at compile time but also 
at
runtime. To make an executable install package like we have at the 
moment
essentially means packaging libgccjit. Which means gcc and half of the 
msys2
toolchain.

We were there a long time back when Emacs used to be packaged with lots 
of other
stuff, including a full python installation. It didn't make sense then 
and it's
not a great thing to go back to.

So, I think, Emacs releases for windows will be without native-comp. 
Anyone who
wants it will have to install it over an msys2 installation, or with 
chocolaty
or something equivalent.

Phil

As far as I understood Eli it should be possible to build Emacs on
Windows --with-native-compilation and distribute it even on systems
without libgccjit.  Only Emacs internal lisp files will then be natively
compiled and if, for other lisp packages, there are no .eln files
available Emacs will just load the respective .elc files.

Do you think I'm mistaken?

We made a point of implementing native-compilation on MS-Windows in a
way that doesn't require such extreme measures.  Emacs built with
native-compilation support should be able to run on a Windows system
without GCC and Binutils installed, it just won't be able to
natively-compile any new or modified Lisp files.  It will use the
*.elc files instead.

Or at least that is the theory.

I could build Gnu-Emacs-28.0.91 when I used the archived sources

  $ ./configure --with-native-compilation

The difference to the build-zips.sh seems to me some more options from
the script (and that is build from the git tree):

        echo [build] Configuring Emacs
        $REPO_DIR/$BRANCH/configure \
            --without-dbus \
            --without-compress-install \
            --with-native-compilation \
            $CACHE \
            CFLAGS="$CFLAGS"

Could it be that these additional options are spoiling the build?
(CACHE=-C , I think.)

I'd drop the CACHE part, so that the configure script starts from a

When I'm removing all the configure options and include
--with-native-compilation in build-zips.sh then - at last - the build
process is creating .eln files...

Wouldn't it be sufficient to copy the native-lisp/ folder into the
distro tree?

Agree, before we rely on this behavior would be nice if someone could
test it tho.

I wouldn't!

CACHE=-C is used only on a snapshot build. These were always built
incrementally from the previous version because I judged that the risk
of a broken build was small compared to the significant time and cost
saving that the incremental build provided. A full build is easy to
achieve by simply deleting the build tree, as build-zips does an
out-of-tree. Reconfiguring requires deleting the config.cache as well.

Full release builds are built from a clean tree. The time saving is less
important there.

--without-compress-install switches off the gzipping of various files,
such as the info files. It was necessary, if I remember correctly, when
I added it because Emacs uses external calls to gzip which wasn't
necessarily bundled.

I do not remember why I added --without-dbus.

Ah, okay. I remember asking about this some time back when I got the
impression this would not work. It's a little bit late in the release
process to be testing the theory now. The last snapshot is a year old,
and that is not native comp.

AFAIU, Dieter said he did more than one build in the same tree for
several different configurations, so I suggested to eliminate the
cache as a possible factor for the problems he saw in the second
build.  Apologies if I misunderstood.

AFAIR, it did work in my (very limited) testing.

I don't see how we could do better, given the (un)availability of
snapshots and pretest binaries for Windows.  Certainly, delaying Emacs
28.1 release until this is tested well enough would be a worse
alternative.

Oh, sure, that's fine. Just saying that the `CACHE=-C` is there for
mostly good reasons!

Of course.  I'm a happy user of -C myself.

Isn't the built-in zip support used for uncompressing things (.el.gz and
.info.gz) when gzip is missing? IIRC that was recently added.

> I do not remember why I added --without-dbus.

Probably because the dbus libraries might be present on the system and
Emacs would pick up them, which is not a good thing.

I'm too inexperienced to judge the options.

But, for the moment, it seems to me when the $CACHE line is active then
there is NO native compilation going on for my builds.  (No idea why,
I'll try to confirm this.)

The current idea is to build 28.0.91 with build-zips.sh - in the usual
way but --with-native compilation - and then copy the lisp-native/
folder into the archive.  Then checking if such a build is running and
actually loading the .eln files on a Windows system without MSYS/MinGW.

Hmm, how can I test if Emacs is actually loading some .eln and not the
.elc files?

That was a genuine question. I'm not sure about the status of that

I have been using describe-function (C-h f) for this  It can tell us if a
given command has been natively compiled (or byte-compiled or neither of
these) for the present session.

Aside: I would first check `native-comp-available-p' to confirm the build
has the native compiler and that the Emacs instance is using it.

Start Process Explorer, and look at the DLLs loaded by Emacs: you
should see there all the *.eln files Emacs has currently loaded into
the session.

I haven't tried! If it does do that now then this switch needs
removing. It didn't when I added it many years back.

If you change the configure options in build-zips.sh, I would go for a
full clean build for sure. "make extraclean" I think will do the trick,
then run build-zips.sh with modified options.

Thank you Phil

And when we are at it, please tell me your recipe how to build a
snapshot of the master branch.  I think my build tree is damaged, I
don't manage to build a snapshot of emacs-29 with a date included..

Shouldn't it be just:

$ build-zips.sh -g
$ build-zips.sh -s

I donʼt know if the builtin zip support works here, but itʼs moot:
zlib support is optional, so you canʼt rely on it always being
available (unless youʼre going to ensure that here).

For Emacs with native compilation enabled, the zlib support takes
another role: if the *.el files are installed compressed, then Emacs
_must_ have zlib support, or else it will be unable to use the *.eln
files, because it must verify the *.el source files correspond to the
*.eln files.  So if you build an Emacs with native compilation, but
without zlib, do NOT compress the *.el file at "make install" time.

We are talking about a binary distribution. Its creator can ensure that
the required dependencies are included on the binary package.

Yes, I think that should do it.

Then, the I build the source like so.

./make-dist --snapshot --no-check --no-changelog
rename .tar _`date +%Y-%m-%d`.tar emacs*.tar.gz
mv emacs-*.tar.gz ~/emacs-upload

I don't think I ever automated this bit.

The model of build-zips.sh is probably a bit complicated and could be
simplified. The addition of snapshots and the ability to build from a
branch makes it much more so and the documentation isn't always well
done. I have been trying to remember why I called the variable
"OF_VERSION" so, or what "OF" stands for, and have failed!

Apologies for this.

Phil

From the point of the windows package, it is under the control of the
packager. If builtin zlib support works on the compressed installed
files, when it can be guaranteed to be packaged.

Uups, I thought this - or similar - would be done by below part of
build-zips.sh?


    make -j 4 $INSTALL_TARGET \
         prefix=$HOME/emacs-build/install/emacs-$VERSION
    cd $HOME/emacs-build/install/emacs-$VERSION
    zip -r -9 emacs-$OF_VERSION-no-deps.zip *
    mv emacs-$OF_VERSION-no-deps.zip $HOME/emacs-upload

    if [ -z $SNAPSHOT ];
    then
        DEPS_FILE=$HOME/emacs-build/deps/emacs-$MAJOR_VERSION-deps.zip
    else
        ## Pick the most recent snapshot whatever that is
        DEPS_FILE=`ls $HOME/emacs-build/deps/emacs-$MAJOR_VERSION-*-deps.zip | tail -n 1`
    fi

    echo [build] Using $DEPS_FILE
    unzip -d bin $DEPS_FILE

    zip -r -9 emacs-$OF_VERSION.zip *
    mv emacs-$OF_VERSION.zip ~/emacs-upload

Not only above is confusing, but also why is

    INSTALL_TARGET="install-strip"

in the script?  (Back to pretest building) I've got an error for

$ build-zips.sh -V28

in the emacs-28 worktree, maybe, that is a wrong usage of the scrip?
Anyway, "install-strip" seems not to be a valid target for make!?

No reason to apologise, it was working for you.  Rather, thank you for
your work. :-)

The console returns an error:

   make: *** No rule to make target 'install-strip'. Stop

But only on a certain machine, on the other I don't see this error.
Need to start from scratch with a new build tree, I think..

On a positive note, but mysteriously enough for me, I found in a package
archive - build with build-zips.sh - a native-lisp/ folder without my
ado (under 'lib/emacs/28.0.91/)!?  And I checked an Emacs from such a
build on an "MSYS Windows system" - with the Process Explorer - loading
.eln files. :-)

Unfortunately this build didn't work on another Windows computer.  It
seems that there are not yet all necessary dependencies in the distro
archive (for example libgmp-10.dll is missing).  I hope Corwin can bring
some light into the build system.

We shall see >:-]

I was able make ./build-deps.zip create a version that (appears as if
it) supports native-comp.

New versions are uploaded to my same Sourcehut repo in a new folder
called "with-native-compilation":

  https://git.sr.ht/~mplscorwin/emacs-w64/tree/master/item/with-native-compilation

I'd be quite interested to learn how these work (or don't) for others.

The hackery I found "successful" is presented at the end of this
message.  In brief, what solved the problem for me was remove -static
from CFLAGS.  You can ignore the swapping of $CACHE and CFLAGS; this
simply made it easier to comment out $CACHE while debugging.

Before removing -static I was running into this:

  #./configure --with-native-compilation CFLAGS="-O2 -static"
  [...snip.. lots of the usual ...]
  checking for gcc_jit_context_acquire in -lgccjit... no
  configure: error: ELisp native compiler was requested, but libgccjit
was not found.
  Please try installing libgccjit or a similar package.
  If you are sure you want Emacs be compiled without ELisp native compiler,
  pass the --without-native-compilation option to configure.

After removing -static build-zips.sh works fine.

I have to assume that "just dumping" the -static flag isn't TRT, so
trying to understand the above error message, code producing it, etc.
will be my next move.  Once I understand that I hope we (I, but feel
free) can work up patches to make building with native compilation the
default when building windows distributables, get the msys pathing
corrected once and for all, and (assuming anything is necessary) fix
configure &ct. to make -static work under msys when
--with-native-compilation is specified.  Notwithstanding -static,
assuming that files linked above are not Just Exactly Perfect then I
am probably understating the remaining work to get back to a "turn
key" windows packaging process.

Here is my "fix" for build-zips:

The top-level Makefile.in has that target, so I wonder how did that
happen for you.

I hate to maybe take you back some steps, but why exactly do you need
those build-zips.sh etc. scripts?  If the problem is to produce a zip
archive with the products of a build (and nothing else), then I can
propose a much simpler solution, which I use for all the ezwinports
binaries.  Interested?

The -static flag was there for a reason, so you cannot just remove it,
you will probably need to do something else in addition.

AFAIR, the -static switch was used due to the libwinpthreads
dependency, and is related to the no-deps package.  We should resolve
this issue now, because using -static is IMO a time bomb, and it
sounds like it just went off on us.

OK, I need to cleanup the whole build tree..

Because I thought that this is the OFFICIALL way of doing Windows
builds, since this script is under admin/nt/dist-build!  But don't
worry, I want to learn a robust and simple way of distributing
Emacs. :-)

I see myself as a backup of Corwin: First I'd like to build a zip file
with Emacs and its necessary dependencies.

Later configured --with-native-compilation.

And later building an installer out of it.

Yes please.  A step by step approach to building Emacs is probably more
successful in the end.

Great, I'll test it later on a "clean" Windows machine (and check your

Makes sense.   How can I help?

One other thing I found is that -installer.exe requires libgmp-10.dll
but either ..
1. only when Emacs is build --with-native-compilation or else
2. only when -static isn't present
I have no idea which, so far.

Looking forward to reviewing/researching further after work today.

As Dieter said (in the other thread) -- I too would very much
appreciate any tips you can share WRT your preferred/personal approach
to crafting the windows binaries/zips.  Thanks so much for that offer.

1. First, I build the package (in this case, Emacs) as usual:

  $ ./configure --prefix=...
  $ make

2. Then I install it in a special place:

  $ make install --prefix=/some/directory

3. Then to produce a zip file with all the installed files, I go to
   /some/directory and invoke 'zip':

  $ zip -9r ./bin ./include ./lib ./libexec ./share ./var

(be sure to mention all the top-level directories).

Now, the tricky part is between steps 2 and 3.  To make the zip file
self-contained, you need to populate /some/directory tree with the
dependencies.  If those are DLLs, simply copy all of them into
/some/directory/bin/.  If there are other dependencies, they should go
in their respective subdirectories (but I don't expect to see any
files outside of bin/ and perhaps lib/).

I think part of the complexity of dist-build scripts is that Phillip
included many more dependencies than strictly needed to run Emacs, so
he needed to put there many programs and files not directly related to
Emacs.  I'm not sure that's justified, but YMMV.

I was struggling to remember what was going on there, and then it hit
me!

This bit of code adds the dependencies. I have to ship the source code
for the dependencies also, but that is produced with build-deps-zips.py.
That doesn't change for an Emacs release cycle (I normally make a deps
bundle at the time of the first pre-test, then do not change it for a
major version).

Source for Emacs is different. I do *not* make source for an Emacs
release build, because I put the Windows binaries on ftp.gnu.org which
is also where the main Emacs release goes which is already a source
release; and as I don't build the binaries till after the source release
happens, this means I fulfil GPL that way.

For the snapshot, I have to release the source code along with the
binaries because no one builds snapshot tarballs (I mean what would be
the point).

This bit does that:

./make-dist --snapshot --no-check --no-changelog

The overly complicated command line was to stop configure being re-run
which then forces a full build when I build snapshots
incrementally. When I used to do them every month or so this was a big
advantage.

Eli suggested it! I think install-strip follows the GNU standards. It
makes the release smaller and the binaries faster, IIRC.

Yeah, but now I struggle to remember what some of it was for. I always
teach my students to comment for this reason and, yet, here I am. Do as
I say, I guess.

In case you haven't see it, there in etc/w32-features.el there are a set
of tests for various features. It's in etc/w32-features.el rather than
the normal test location so that it is present in the windows binary
release. It's a nice way to check whether the build has worked (I use
.emacs on my test machine to automatically load it).

Anyway, you might want to add a test for native comp working to
there. It will make your life easier!

Yep, libwinpthreads was the problem.

It only affected the no-dependency version of Emacs which has other than
libXpm, no dependencies. Without -static it broke complaining about
libwinpthreads.

Nasty hack. Well worth checking whether it is still a problem (it comes
from msys2 and that's changed lots). And if it is, worth wondering
whether no-deps is still needed.

I used to produce multiple binaries: with deps, without multipled by
32bit/64bit. And, they had to be done by hand and in the right order
(once the deps version has been produced the install tree is no longer
clean), and also one at a time. As this process took many hours, scripts
were necessary, so I didn't have to stand over it.

Some of that has dropped away now, but in the mean time, I added the
NSIS installer to build-zips. That functionality exists nowhere else in
Emacs. Also the "build a snapshot with a dated name" functionality. So
that would have to go somewhere, if not in build-zips.sh.

I did it that way for a long time.

No, it's not that. The dependencies are now fairly small and now all
essential. Besides the dependencies were added simply by unzipping the
dependencies bundle.

The script that produces the dependencies bundle is rather simpler than
it used to be.

First I checked your signature.

At first I couldn't find your key on a keyserver, then I found a hint on
your sourcehut site.  Didn't you made your key public?  And is it
necessary to limit the key duration?

On an MSYS Machine I could start Emacs from your archive.  But there are
constant warnings:

  Warning (comp): e:\Corwing\emacs-28.0.91_eln\bin\libgccjit-0.dll: error: error invoking gcc driver. Disable showing Disable logging

  ...

Sadly on a "pristine" Windows machine I couldn't start Emacs from the
unzipped archive!  Your build has the same problem than mine.

  libgmp-10.dll

and probably more, are missing in the tree.  It seems that either
something is wrong with build-dep-zips.py. or not all .DLLs are copied
into the archive.  (Your installer I didn't check..)

Hello Phil

Thank you for your messages, I'll pause and study them tomorrow.

What I meant to say is that, at the moment, our builds are failing,
without me knowing what's going on.  Without much build experience it
might be better if I slowly learn to build things step by step - like
you did - and then coming back and using your scripts in a dignified
way.

My key is on Savannah, as I assume you've discovered.  I think this is
the expected/required to upload to (either) FTP location.  AFAIK
having *some* duration is required but I haven't looked into that; I
simply accepted the defaults when creating it some time back.

I believe we just need to add this to the make-deps-zips.py (see the
big lists at the top of that program); I'm not sure yet which of these
to edit.  In any case, I'm /fairly/ confident this is the only "gap".

> into the archive.  (Your installer I didn't check..)

Apologies; only the installer is likely to work because that one I
re-created (build-zips.sh -i) after adding manually adding
llibgmp-10.dll into the deps zip file.

I'll fix up make-deps-zips.py once I can confirm that the
("hand-corrected") installer actually works for someone.  I'm so glad
you have a clean windows environment to use for this testing, and
thanks so much for checking my work.  I wish I could return the favor;
my windows environment isn't anything like sanitary.

Can I ask you to give my install.exe a whirl and confirm that libgmp
was (as I believe) the only issue?  I'll rebuild the full set
(including correcting build-deps-zips.py) as soon as I have that
confirmation.

Yay for progress Deeter; can't wait to work more on this in my evening!

Ah I didn't expect that your installer had some "extra", nice. :-) Sure,
I'll give it a try this evening.

Please tell me if the uninstaller can remove all remnants of an Emacs
installation, or do I have to clean some parts of the registry or
whatever?

Thank you

Thanks so much Dieter!

If we find it isn't removing something it creates I think we should
open bug-reports for that specifically.

I'd been forgetting my daughter's birthday yesterday morning when
planning my day/evening; tonight I have other commitments. I look
forward to getting back into this and a few other things Emacsian
Friday or over the weekend.

I'm sorry to say but the problem with the missing libgmp-10.dll remains
also in your installer.

I checked the Emacs-27.2 installer as well as the zip archive and both
are working as expected on this machine.

Some minor observiations:

1. The uninstaller isn't removing a link to runemacs.exe.

2. The installer has the Gnu(s)-Emacs image aspect ratio rather
   distorted.

3. The installer default is "c:\Program Files\Emacs" I think it would be
   cleaner when the installation tree includes the version number.

Why?  The Emacs installation tree is designed to accommodate more than
a single Emacs version simultaneously.  Using versioned directories
would mean users need to tweak their PATH each time they install a new
version, which is undesirable and unnecessary.

What are your reasons for using versioned installation trees?

I found myself up triaging some things for another project I support,
so kicked off a new build.  These include pushes to the emacs-28
branch though today up to approximately 10pm US/Central.  I think
these new versions may do the trick.   A patch-set is attached for
changes to the admin/nt/build-*zips* scripts.  You will see that I'm
still building without -static; I haven't had a chance to dig into
that yet.

  https://git.sr.ht/~mplscorwin/emacs-w64/tree/master/item/with-native-compilation

Would you be able to try again with this version of emacs-28.0.91-installer.exe?
In fact, all of the packages in the linked folder should work now AFAIK.

I think this should get a bug report (assuming it's still happening
with the above-linked versions).

This feels like a lower priority but maybe it too should be tracked
with a separate bug report?

I see you are already discussing this one with Eli; I'll leave it to
the two of you as Eli's thoughts appear to echo my own here.

Stupid me, I meant Emacs' release numbers not "version" numbers!

At the moment Emacs will be installed per default into

c:\
  |- Program Files\
     |- Emacs

If you intent to install another Emacs release and forget to change the
installation directory "Emacs" then - without warning - the new release
will be installed over the old one.  Is this supposed to work for major
release numbers?

Wouldn't it be better to install Emacs in a tree with the release
numbers?

c:\
  |- Program Files\
     |- Emacs-27.1
     |- Emacs-27.2
     |- Emacs-28.0.91

No, it won't be installed "over the old one", it will be installed
_in_addition_to_ the old one.  the old Emacs binary will still be
available, and all the support files will still be there.

Why did you say "over the old one", and what did you think would
happen when such an installation is done?  I think you might be having
an inaccurate mental model of what happens when a new Emacs version is
installed "over the old one".

This is the NSIS installer I wrote? It should include a version number,
but I think with a common top level directory (I can't test it at the
moment).

Yes Phil, I checked it with 27.1 and 27.1. Both releases are installed
into the same tree:

c:\
  |- Program Files\
     |- Emacs\

(without manual intervention).

The release number appears under the share\ folder.

c:\
  |- Program Files\
     |- Emacs\
        |- x86_64\
           |- share\
              |- emacs\
                 |- 27.1

You should also see a versioned subdirectory under libexec.  (And with
Emacs 28, also under lib.)

This is normal, and has nothing to do with the Windows installer.
It's how the Emacs installation tree looks on all platforms.

Hmmm.

As you say, installing multiple versions side-by-side works fine and 
does not need to have
a version number in the install directory. ("C:\Program Files\Emacs"). 
Actually, the "x86_64" is
not needed now, but I guess I left that in for backward compatibility.

But, the uninstall section looks like this:

Section "Uninstall"

   # Always delete uninstaller first
   Delete "$INSTDIR\Uninstall.exe"

   # now delete installed directory
   RMDir /r "$INSTDIR"
   RMDir "$INSTDIR"

   !insertmacro MUI_STARTMENU_GETFOLDER Application $StartMenuFolder

   Delete "$SMPROGRAMS\$StartMenuFolder\Uninstall.lnk"
   RMDir "$SMPROGRAMS\$StartMenuFolder"
SectionEnd



So, I think there will only be a single uninstaller. Uninstalling will 
remove all versions of Emacs because it just deletes the INSTDIR. 
Likewise, there is a single start menu item which will overwrite the 
last installed Emacs.I guess this makes sense. In windows land, 
installing Emacs-28 would be expected to remove Emacs-27. If all older 
versions of Emacs get left behind, that would generally be considered a 
bug. I don't remember whether NSIS runs the previous uninstaller first, 
that might be checked.

So, side-by-side installation will work but it's not by design and while 
the installer supports it, the uninstaller will not respect it.

My feeling is, therefore, the current set up is correct. If you want to 
run multiple versions of Emacs, use the zip file.

Ah, I was always wondering why there is an emacs.exe AND an
emacs-27.2.exe. :-)

It'll work for the libexec\ and share\ branches.

But I'm afraid, currently, not for all files in the bin\ branch, they'll
be overwritten after a default (side-by-side?)  installation.  For
example runemacs.exe and emacsclient.exe are then only working for the
last installed release.

For Emacs-27 there are more than 150 .exe files, moreover .dll and
scripts in bin\.  Maybe this will work if one is installing ever newer
releases but in the opposite case, I'm not sure..

(But I guess few Windows users intend to run multiple Emacs releases,
just using the latest and greatest.)

By the way.  Would you mind to tell me why an emacsclientw.exe together
with emacsclient.exe is needed and what emacs.pdmp is for?

I admit I had a wrong mental model of Emacs' tree organisation.  I think
all software I'm installing on Windows is using a different
approach. :-) Every release is installed in a separate tree.  So I'm
looking forward to learn the advantages of Emacs' organisation.

Thanks a lot

Then that is the problem to fix: how Emacs is uninstalled.

Or maybe it's a feature that it uninstalls all the versions?

In general, I see no reason for anyone to ever uninstall Emacs.  But
that's me.

We are in Emacs-land, not in Windows-land.  Emacs on Windows tries to
behave like on any other platform, from this POV.

It is not a bug, it's a feature: old versions are still available
after installing new ones.  If someone reports this as a bug, we will
explain why it isn't.

I disagree.  I think it will be confusing to have different
installation expectations depending on whether a zip file or an
installer were used.  They should both yield the same results.

Should the uninstaller detect when several versions are present in the
installation path and then prompt the user to select which ones to
remove?   I assume we would then make removing the installation folder
conditional on the user selected "Remove all versions" or something to
this effect.

Why is that a problem?  the old versions can still be invoked, just
not via the default methods.  Which is exactly the expected result
when installing a newer version.

Be sure.  I'm doing this on my system all the time.

Most of them, yes.  But there's no reason to force them to remove the
old version.

That's explained in nt/README.

That's the preloaded packages that are dumped when Emacs is built and
loaded when Emacs is started.

I can confirm this (for Emacs-27 releases, side-by-side) there's then
only one uninstaller (left?) and it will remove the complete Emacs tree
per default (optionally, I think, it offers to remove parts of the
tree).

Ideally, the uninstaller should only remove the files that the
installer installed, it should not remove entire directories if those
directories include files not installed by the installer.

"Remove all version" should be a separate feature, IMO.

True it's possible to run the Emacs-27.1 executable after installing
Emacs-27.2 (checked it).

But I see no way to run an 27.1 release of emacsclientw.exe or
runemacs.exe!  (I don't like this unsightly and useless terminal window
when not starting from runemacs.exe.)

Wouldn't it make sense to provide also emacsclientw-27.1.exe and
consorts?

Just copied an Emacs-26 tree "over" Emacs-27.

Emacs-27.2.exe still seems to work but I've got a bad feeling replacing
newer "support stuff" with older..

By the way, with Emacs-26 and 27 there's an issue with the network
manager when running M-x list-packages (certificate expired or not
verified).

After that, I've take the last Emacs snapshot 28.0.50 for Windows and
copied it "over" above tree.  Now the certificate issue is gone.

By implication, this means if I'm "ironing" Emacs-27 over Emacs-28 I'll
get a problem.  As I wanted to say, it is probably safer doing
side-by-side installations from older to newer releases and never the
other way around.

Thank you, but I need to run emacsclient on Windows to understand it
fully.

I see, not all necessary data must be packed into one executable, for

I don't see any reason, because we don't change the server protocol in
backward-incompatible ways.

IME, there's no real reason for you to feel bad.

If you downgrade Emacs, then yes, you get to live with old problems
that are already fixed in a newer Emacs.  Why is this a surprise?  You
also get back all the bugs that were fixed between Emacs 27 and Emacs
28, right?  Would you call that a problem with the installation
procedure or with the structure of the installation tree?

Like I said, there's no reason to think so.

Because there is no i686 any more. You could install them both together.

Yes, that's true, but Emacs does not ship an installer on any other
platform. The Windows installer has to behave uniquely for that reasons.

Although, I would say that most of the binary packaged versions of Emacs
do the same thing. The debian .deb is a single version (27.1). A new
release will remove the old one.

You could:-) I'd agree with the bug report. But, as I have stepping back
from making the windows version, I'm easy with which ever way it goes.

It doable, although with the directory layout as it is, it is slightly
more complex. If we want to do this, I would add a top level-directory
with the version number in. The uninstaller just deletes this. The start
menu items will need updating also, so there is not just one.

The zip file doesn't bring any expectations. It just unpacks where every
you want it, and doesn't install any short cuts. You get the same Emacs
but all the directories are clearly different. In that sense, the zip
file is equivalent to a portable app. The installer version is not. The
latter is what most people would be expecting.

In the "official" binaries, there's no i686, because MinGW64 basically
tossed support for that.  But mingw.org's MinGW still supports it, so
a user could theoretically build such an Emacs, or ask someone else to
build it, and then install it alongside the 64-bit one.

And then there could be a Cygwin build, which will be installed into a
separate subdirectory of libexec, even though it's a 64-bit build.

So I think there's a good reason to keep the architecture
subdirectory.

I provided my opinions, but since I'm not the one who will do the
work, feel free to disregard them.

Currently, I think, the installer doesn't offer to uninstall the
previous version, although I have only tested it on wine. I would have
assumed it did.

So, we have an half-and-half world at the moment. It doesn't install
multiple versions cleanly, nor does the "update to a new version"
functionality work cleanly. You have to uninstall the old one first.

None of this will result in an unfunctional Emacs, so it's not a
disaster. But I think it should do or the other.

If there were such a thing, my guess is that they would install it
somewhere entirely different. But it adds no complexity, so I am easy
either way.

Likewise! I think we have had a good discussion of the pros and
cons. The final decision can rest with Dieter and Corwin.

I can't find libgmp-10.dll in your emacs-28.0.91.zip archive and when I
run the installer - on a system without MSYS/MinGW - it still bails out
because of the missing libgmp-10.dll.

I've pushed new versions.  I was able to test the new installer.exe on
my son's gaming rig, so I'm rather confident that, at least, works.

I hope someone with a working msys can confirm that this supports
native-compilation when msys+libgccjit is available.

Corwin

So you installed Doom-Emacs? ;-)

In earnest: I could start Emacs from the installer, great. :-)

Then I checked it with M-x list-packages and received the following
*Messages*:

  gnutls.c: [1] (Emacs) GnuTLS library not found [4 times]
  Package refresh done

I don't know how important this is, though.  I'm wondering if we could
automate such build testing with existing ert tests?

Some more observations (no criticism).

Signing: When I check the downloads gpg says:

  Good signature. Warning: This key is not certified with a trusted
  signature!

Would it help, be appear more trustful, when I sign your key?

Size: Your installer and emacs-28.0.91 builds are smaller than Phil's.
I assume you didn't copy the source code?

Installation tree: I've seen that you skipped the x86_64 branch.

> I hope someone with a working msys can confirm that this supports

I'm sorry, forgot to check it on my MSYS machine, will do tomorrow.

And now for something else: Would you expect it to be problematic when
we build on Windows10 for Windows11 or vice versa?

Have a nice evening

No, there should be no problem like that.

I'm having trouble replicating this.  I see libgnutls-30.dll (and also
libgnutls-openssl-27.dll?) in both the -deps.zip and inside
with-native-compilation\emacs-28.0.91.zip

Any thoughts on what could be up here?

Hmm.  I've uploaded my key a few places (in addition to posting on
Savannah).  I can look for other places to publish it -- any
suggestions?

I don't think I quite understand this suggestion -- not a rejection.
Likely, you are wiser than I in the ways of GPG.

I'm fairly sure the binary release packages have never included
source.  I suspect the size difference is accounted for by omitting
-static while compiling.

Can you elaborate?  Is this a difference between my prior versions and
the current, between what Philliip was producing and what I've been
making, or somehow .. both?

Quite alright -- as I mentioned in the new thread[1] from today, I was
able to test the installing to a machine with a working msys (on path)
does enable native compilation to work, so I'm feeling a bit less
pressure on that score.  Don't get me wrong: I'll be very happy when
you are able to take a look.

No, I'm not expecting any differences between Windows 10 and Windows
11 that we'll notice WRT the packaging process we are using.   That's
not a super expert opinion, to be sure.  I can likely give the
installer a try under Windows 11 next week sometime.  I'll report back
directly in case of any supprises.

Thank you 

I think it would be helpful for (some interested) users either to have
it directly at the ftp site (in the gnu-keyring?) or to make / announce
your key know to public keyservers.

It's probably not yet spread on public keyservers.

  $ gpg --keyserver hkp://keyserver.ubuntu.com --search-key corwin@bru.st

You could announce your key on keyservers thus

  $ gpg --keyserver hkp://keyserver.ubuntu.com --send-key corwin@bru.st

I guess only few users will actually check if their download is valid
with the .sig file...  But I remember how annoying it was to search for
a key, when the old key of the developer was expired.

I'm not wiser and most likely this signing of keys isn't worth the
trouble since it seems that Emacs developers just include their keys
into the gnu-keyring and don't build a Web of Trust around it, like, for
example, the Debian project.

Phil's installer (and archives) with a default installation:

c:\
|- Program Files\
   |- Emacs\
      | x86_64\
        |- bin\
        |- ...

Your installer:
c:\
|- Program Files\
   |- Emacs\
      |- bin\
      |- ...

I didn't comment yet on [1] because I think, in summary, your focus is
well thought out and you don't let yourself be too distracted from my
"firing" on the side-line. :-)

Some observations regarding the native compilation:

After runing Emacs native compilation started immediately till all
el. files were compiled to .eln.  I check with the Process Explorer that
these files are loaded as well.

It seems that you've configured Emacs to do the compilation
"as-soon-as-possible" and not "just-in-time" :-)

Then, unfortunately, for each .eln file (96) there remains an
accompanying .eln.tmp file in the eln-cache!?

When updating some packages (M-x list-packages) these were then native
compiled and respective .eln.tmp files vanished.  (But still not the
.eln file which were compiled in the beginning!)

No such configuration.

Doesn't happen here: those .eln.tmp files are renamed to .eln at the
end of the compilation.  What version of libgccjit do you have
installed?

Since I forgot to check with emacs -Q, I assume (now) all lisp files
which are loaded by my init.el.

When doing emacs -Q nothing is compiled at first, the eln-cache remains
empty.  After loading init.el Emacs is beavering away for some minutes
(4 cores, with virus scanners active). :-/

I can't reproduce the zero size .eln.tmp files anymore.  Maybe that was
an issue with org-mode from an old org-elpa package which I changed in
the meantime from the gnu archive?  That's the only idea which comes to
mind...

When updating packages the native compilation works as well.

So for the moment, everything looks promising! :-)

I updated the system quite recently.

$ pacman -Ss libgccjit

mingw64/mingw-w64-x86_64-ligccjit 11.2.0-6 (mingw-w64-86_64-toolchain)
[installed: 10.3.0-2]

This is normal and expected.

There was no purpose behind it, except saving traffic to this long

up with the cores vs. logical processors questions.

Could you please tell me how to measure the compilation time of Emacs
without a stopwatch, how would you do it?  I'm interested in how
compilation time is scaling when I'm using all available logical
processors..

What do you mean by "compilation time of Emacs"?  What is the
compilation that you want to time?

Oh right, I could check the time compiling Emacs simply with

 $ time make -j8

In the thread's context I meant the time it takes with an empty
eln-cache to compile all .eln files after loading the init file.

I'm not aware of any facilities, except noting the time when the
compilation started (i.e. when you start Emacs), and then looking at
the time stamps of the produced *.eln files.

When using the executables to open files, it seems, emacsclientw.exe is
to emacsclient.exe what runemacs.exe is to emacs.exe (with the former no
additional terminal windows are popping up :-) ).

Not exactly.  emacsclientw is the no-wait variant of emacsclient, not
a don't-show-console variant.  IOW, emacsclientw is appropriate for
using from GUI programs that don't (and cannot) wait for Emacs.

I'm not sure why this is.  Could you be comparing packages from
Phillip for a full release vs mine for a pre-release?   Other than
that the only thing I can think is that perhaps I'm not executing one
or the other script from the expected folder/CWD.

Phil,  thoughts/theories?

In any case, apart from the pending/on-going discussion of what
changes to make to installer/uninstaller (and then, how critical such
changes should be considered), I feel this is probably not a show
stopper:  So far, I still think we can push the prerelease to alpha
as-is and I'd lean toward not making any change around this prior to
28.1.  WDYT?

Thank you for the details. (From nt/README I understood it only as a

Why is the folder ./var necessary?

It seems that only

   libgmp-10.dll

is a prerequisite to get Emacs (28.0.91) running on a Windows system
without MSYS and

   libXpm-noX4.dll

provides a nicer logo and icons.  (I didn't test much functionality
yet.)

In /nt/README.W32 is a list of further dependencies provided in MSYS2
packages:

    mingw-w64-x86_64-giflib
    mingw-w64-x86_64-gnutls
    mingw-w64-x86_64-libjpeg-turbo
    mingw-w64-x86_64-libpng
    mingw-w64-x86_64-librsvg
    mingw-w64-x86_64-libtiff
    mingw-w64-x86_64-libxml2
    mingw-w64-x86_64-xpm-nox
    mingw-w64-x86_64-lcms2

are above dependencies considered as the absolut minimal set for a state
of the art Emacs under Windows?

Thanks! I'll see if that could be a gap somewhere in the build
process.  The windows release builds seem to have a pretty ugly logo
on the splash.

Here is the list from build-deps-zips.  I'm fairly sure at least
harfbuzz and jansson should be added, but I strongly suspect the list
in the script is a good one (at least, I like the emacs release
packages Phillip has been creating).

mingw-w64-x86_64-giflib
mingw-w64-x86_64-gnutls
mingw-w64-x86_64-harfbuzz
mingw-w64-x86_64-jansson
mingw-w64-x86_64-lcms2
mingw-w64-x86_64-libjpeg-turbo
mingw-w64-x86_64-libpng
mingw-w64-x86_64-librsvg
mingw-w64-x86_64-libtiff
mingw-w64-x86_64-libxml2
mingw-w64-x86_64-xpm-nox

Removing the intersection of these gives me:

mingw-w64-x86_64-harfbuzz
mingw-w64-x86_64-jansson

However, when I look a little further down the script at the DLLs that
we'll bundle, I note that xpm-nox is missing from the latter list, so
that probably confirms the change needed per comments above.

I will test that I confirm back.

> are above dependencies considered as the absolut minimal set for a state

Do you want to patch the documentation while I further mangle Phillips scripts?

PS, not intending to side track the "simpler path" conversation you
are having with Eli, here, but I do think we should carry what we
learn back to the scripts that appear to do the job now.   In all
events, I suspect jannsson and harbuzz should be documented in
README.W32 in *some* fashion.

Stange, the ugly logo didn't occurred to me with Emacs from your
installer?

(And Phil mentioned this dependency explicitly in
admin/nt/dist-build/README-scripts.)

It would be good if you document your changes and when I'm ready I can
proofread them.

I don't see your files on
   https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-28/

didn't the GNU administration respond to your request yet?

It's pretty obvious here, but maybe because I have an unusually
colored background in my default theme: the lack of transparency for
the image on the splash page is pretty unsightly.  But maybe I'm
overreacting.  See attached.

Sure, I'll get to it then.  I'll file a bug and CC you in expressly
when I have a patch.

I'm awaiting confirmation that I've done the needful (correctly) and
that my upload permissions are in place.

It lets emacs do a bunch of JSON processing in C rather than elisp, which
is very helpful for a bunch of cases, especially some LSP modules.

Just in case: Language Server Protocol; a semi-standard way for outboard
toolsets like specialized compiler suites to communicate with editors
(primarily VSCode, but somewhat generalized and so supported in other
editors as well) about things like code completion and language-aware
editing. The protocol ends up being pretty chatty, often sending a lot of
json back and forth, and the pure-elisp method of converting it had a
pretty high overhead.

It was used at some point in the past.  If it doesn't exist in the

They are not the "absolute minimum", but they are nice to have, yes.
Assuming you built Emacs with all those features, of course.  But the
up-to-date list is in nt/INSTALL.W64, and it includes a few more
packages (notably, HarfBuzz).

I see, yes, could be nicer if the png were transparent.

(Without libXpm-noX4.dll the image is drawn only in black & white.)


An aside regarding dependencies: When I'm starting Emacs from your
current build from an MSYS2 shell I'm getting this warning:

  gnutls.c: [1] (Emacs) GnuTLS library not found

Even though libgnutls-30.dll, libgnutls-openssl-27.dll and
libgnutlsxx-28.dll are in Emacs' bin/ directory.

This warning doesn't appear, when starting Emacs from an Mingw64 shell.
Sigh, it seems when it was build under MinGW64 it has to be started from
such a shell?

Check the dependencies of libgnutls-30.dll, perhaps they are not on
PATH.  (They should ideally be in the same directory as
libgnutls-30.dll itself.)

No, it just means your PATH is different in MinGW64 shell.

Thanks a lot for the hint!

  $ rm -r eln-cache/
  $ date && emacs
  $ date -r latest/eln-cache/file

That worked for me doing a quick check:

I'm curious about the hyperthreading potential on my 4 core Intel laptop
for doing compilations. And checked Emacs-28.0.91 from Corwin with (setq
native-comp-async-jobs-number 8) vs 4 jobs.  My init.el forces Emacs to
compile over 200 .eln files and it took about 5'40" with 8 logical
processors and 7'7" with 4 logical processors.

Thanks for the explanation Chad, even though I never got in contact with
LSP, your remarks gave me the idea to look in another way to the
"standard" dependencies of Emacs.  Namely, that the "standard" is what
developers are are activating - or trying to activate - in the configure
script.

How many execution units you actually have there?

I think you mean with "execution units" what the task manager calls
"cores".  This computer has 4 cores and 8 logical processors as you can
see in the attached image from it's task manager.

If all you have is 8 execution units, using them all for compilation
will indeed not show twice the speed as with 4 jobs, because the OS
needs some of the CPU resources to do its job.

I generally find the default of half the execution units used for
background native compilation as adequate: it lets me work in Emacs
with almost no visible slowdown while JIT compilation goes on.

Yes, it's true that the OS needs resources, but it's not the major
effect on machines with Intel CPUs (hyperthreading enabled, I don't have
experience with AMD processors.)

Here's the same test for 6 and 3 native-comp-ansync-jobs (4 core CPU)

  6 jobs : 6'12"
  3 jobs : 8'23"

That's roughly what I experience with simulation software as well.  The
heavy lifting is done by cores, the number of "logical processors"
doesn't scale.  (Usually we are doing long running simulation jobs with
the number of cores - 1.)

I assume for editing tasks it doesn't matter if all cores are used by
compilation and the system load is low.

I'm not tracking this development, so please bear with me.  Is the plan
to unpack the file emacs-28.0.91-no-deps.zip into, say C:\emacs and
unpack the .dll from emacs-28-deps.zip[1] into C:\emacs\bin?  If so, I'm
afraid that the compiled features will not work since dependencies are
missing in emacs-28-deps.zip, e.g.:

1)  libgnutls-30.dll has these dependencies:

libgcc_s_seh-1.dll is an important one and IIRC, this dependency was the
one pushing Phillip into packaging the GCC source next to his binaries.

I checked the dependencies with cygcheck program shipped with Msys2 (and
snipped the standard Win libraries)

That should work.  Unpacking emacs-28.0.91.zip somewhere should be a
short-cut for that, exactly.

IIUC, there is special-casing in the dependency packaging script that
prevents "recursing" exactly this chain:

$ grep -C1 gcc build-dep-zips.py
## Packages to fiddle with
## Source for gcc-libs is part of gcc
SKIP_SRC_PKGS=["mingw-w64-gcc-libs"]
SKIP_DEP_PKGS=["mingw-w64-glib2"]

I surmise people who want TLS (just as, now, people who want
native-comp) must install MSYS2 and place it's bin directory directory
on the windows path before starting Emacs.

If we want source zips to include gcc then we can probably do likewise
for gccjit.  To me, it sounds to if native-comp (and TLS) "just work",
i.e. so people don't need to hand-install MSYS2 to use the
"batteries-included"  versions of the binary distributions for
windows.

I'll do some experimentation.  I'd like to understand what this does
to the packaging times and file sizes. If this is something we are
already sure that we don't want to do, please let me know.

I'm not sure about TLS, I had the impression that Emacs relies on the
.dll only.

My point was that currently the file emacs-28-deps.zip lacks
dependencies.  Take for example 3 files from the .zip libpng16-16.dll,
libturbojpeg.dll and libxml2-2.dll.  I've marked the missing
dependencies with '*' below:

Found: C:\path\to\msys64\mingw64\bin\libpng16-16.dll
C:\path\to\msys64\mingw64\bin\libpng16-16.dll
  C:\path\to\msys64\mingw64\bin\zlib1.dll *

Found: C:\path\to\msys64\mingw64\bin\libturbojpeg.dll
C:\path\to\msys64\mingw64\bin\libturbojpeg.dll
  C:\path\to\msys64\mingw64\bin\libgcc_s_seh-1.dll *
    C:\path\to\msys64\mingw64\bin\libwinpthread-1.dll *

Found: C:\path\to\msys64\mingw64\bin\libxml2-2.dll
C:\path\to\msys64\mingw64\bin\libxml2-2.dll
  C:\path\to\msys64\mingw64\bin\libiconv-2.dll *
  C:\path\to\msys64\mingw64\bin\liblzma-5.dll *
  C:\path\to\msys64\mingw64\bin\zlib1.dll *

Hence, people without an installed and available Msys2 (in $PATH) won't
be able to open a .png file in Emacs.

Yes, all the dependency DLLs, recursively, should be available to
Emacs, otherwise it will fail to load some of the DLLs, and the result
will behave as if the relevant DLLs (such as libgnutls-30.dll) were
absent.

The GnuTLS library is very important to have, as without it many
features, like package.el and EWW, will be unable to work, or will be
very limited.

I think you are right Corwin with respect to native compilation. Eli's
opinion is that we don't have to pack the dependencies for Windows.
Please see the thread:

  https://lists.gnu.org/archive/html/emacs-devel/2022-01/msg01020.html

For other "convenience dependencies" he advised me to look at
nt/INSTALL.W64.  Here's the list of packages for features which,
ideally, should be available in a GNU-Emacs distro out of the box on
Windows:

  mingw-w64-x86_64-xpm-nox \
  mingw-w64-x86_64-libtiff \
  mingw-w64-x86_64-giflib \
  mingw-w64-x86_64-libpng \
  mingw-w64-x86_64-libjpeg-turbo \
  mingw-w64-x86_64-librsvg \
  mingw-w64-x86_64-lcms2 \
  
  mingw-w64-x86_64-jansson \
  
  mingw-w64-x86_64-libxml2 \
  
  mingw-w64-x86_64-gnutls \
  
  mingw-w64-x86_64-zlib \
  
  mingw-w64-x86_64-harfbuzz

So I'm more in line with Arash: Image-, XML-, TLS-, json-,
(un-)archiving- and some text shaping support should be available.

> My point was that currently the file emacs-28-deps.zip lacks

Yes, thank you Arash for pointing this out.  (Did a quick check, TLS is
not working, PNG viewing and EWW is not connecting to https sites.)

Currently we have 19 DLLs in the /bin folder (28.0.91), whereas 27.2 has
77 DLLs!  Corwin could you please check your build configuration, maybe
together with Phil?  (I'm sorry, I'm still of no help here.)

Excellent observation.

I hope Phil will chime-in with suggestions of what I may have
missed/broken.  I'll investigate also, obviously, and others'
kibitzing most welcome too.

Meanwhile, I suggest we should solve this problem before pushing
28.0.1 to the apha FTP site.  I don't want people to have different
expectations (needing to install MSYS) vs 27.1 and the pre-releases
Phillip created for that.

(Phil, is "Phil" fine? Preference for "Philip"?  I obsess on the oddest things.)

I think I've got, at least, a workaround!

I realised that ntldd.exe doesn't show any msys/mingw dependencies at
all, only Windows stuff! -> So I removed all Windows references from
PATH.  (Don't ask me why ntldd searches Windows paths first.)

Then, it seem's, that the msys/mingw people changed the tree layout of
their files!  When I'm changing "msys64" with "mingw64" in
build-dep-zips.py:

  def ntldd_munge(out):
      deps = out.splitlines()
      rtn = []
      for dep in deps:
          ## Output looks something like this

          ## KERNEL32.dll => C:\Windows\SYSTEM32\KERNEL32.dll (0x0000000002a30000)
          ## libwinpthread-1.dll => C:\msys64\mingw64\bin\libwinpthread-1.dll (0x0000000000090000)

          ## if it's the former, we want it, if its the later we don't
          splt = dep.split()
          ## if len(splt) > 2 and "msys64" in splt[2]:
          if len(splt) > 2 and "mingw64" in splt[2]:
              print("Adding dep", splt[0])
              rtn.append(splt[0].split(".")[0])

      return rtn

It copies much more DLLs to the deps folder.  :-)

(Oh dear, as if the whole building process wouldn't be complicated
enough..)

I hope so, at least he signed his emails himself repeatedly with
"Phil"... ;-)

Are you saying that you have dlls with the same name under /mingw64 and
/Windows ?

No, we didn't.

Probably your MSYS2 install is not in a directory named "msys64" (the
"in" operator in Python is case-sensitive, isn't it?)

Hello Chad

could you please give a minimal setup to test the jansson library for
the language server protocol?  Is it enough to create a json file, setq
a default server address and search for function names? :-)

Thanks a lot

       Dieter

I'm not Chad, but what's wrong with test/src/json-tests.el?

I once wrote a small script to find out the dependencies myself.
Suppose these are the required DLLs for the features you want Emacs to
compile with:

libXpm-noX4.dll
libgif-7.dll
libgnutls-30.dll
libharfbuzz-0.dll
libjansson-4.dll
libjpeg-8.dll
liblcms2-2.dll
libpng16-16.dll
librsvg-2-2.dll
libsqlite3-0.dll
libtiff-5.dll
libwebp-7.dll
libxml2-2.dll

Then you should have these DLLs available:

libbrotlicommon.dll
libbrotlidec.dll
libbz2-1.dll
libcairo-2.dll
libcairo-gobject-2.dll
libdatrie-1.dll
libdeflate.dll
libexpat-1.dll
libffi-7.dll
libfontconfig-1.dll
libfreetype-6.dll
libfribidi-0.dll
libgcc_s_seh-1.dll
libgdk_pixbuf-2.0-0.dll
libgif-7.dll
libgio-2.0-0.dll
libglib-2.0-0.dll
libgmodule-2.0-0.dll
libgmp-10.dll
libgnutls-30.dll
libgobject-2.0-0.dll
libgraphite2.dll
libharfbuzz-0.dll
libhogweed-6.dll
libiconv-2.dll
libidn2-0.dll
libintl-8.dll
libjansson-4.dll
libjbig-0.dll
libjpeg-8.dll
liblcms2-2.dll
libLerc.dll
liblzma-5.dll
libnettle-8.dll
libp11-kit-0.dll
libpango-1.0-0.dll
libpangocairo-1.0-0.dll
libpangoft2-1.0-0.dll
libpangowin32-1.0-0.dll
libpcre-1.dll
libpixman-1-0.dll
libpng16-16.dll
librsvg-2-2.dll
libsqlite3-0.dll
libstdc++-6.dll
libtasn1-6.dll
libthai-0.dll
libtiff-5.dll
libunistring-2.dll
libwebp-7.dll
libwinpthread-1.dll
libxml2-2.dll
libXpm-noX4.dll
libzstd.dll
zlib1.dll

Maybe you want to double check this with your results.

HTH.  Best, Arash

Hurraaah, there are already tests for it!

Thanks a lot Eli.

How nice, we can test the dists with image-tests.el, json-tests.el,
lcms-tests.el and xml-tests.el.  And I had the impression that tests are
only working in batch mode!

For the archiving (zlib) calling Info should work, for gnutls calling
eww and for harfbuzz, I think, checking the persian language environment
could do, or can we use for this some character or font tests?

I hope nothing, because that's what I was going to suggest. :-)

I also note that there is some #ifdef WINDOWSNT code in src/json.c that
checks for the jansson library near the top of DEFUN ("json-serialize"...
that suggests it will signal a useful error if it can't find the library,
and json-serialize is heavily exercised in test/src/json-tests.el, so as a
specific check, "cd tests; make json-tests" should do the job.

Hope that helps,
~Chad

Oh, there's also a makefile and a README!  Damn, before your post I
bombed already the mailing list with, potentially, redundant questions.

HarfBuzz's functionality has nothing to do with Persian specifically,
it is a general-purpose text shaping engine.  Just "C-h h" followed by
"C-u C-x =" on some exotic characters should do to test it's working.

I don't know, I haven't looked at it in this way, just realised that
there were many Window system DLLs . I'll send you a sample, if you want
to see it with your own eyes..

(I'm sorry I'm answering this with another computer.)

Good! Then perhaps I, and probably Corwin as well, were installing
mingw/msys in another way as Phillip Lord did.  I will check
nt/README.W64 how the installation process is recommended.

Yes :-)

Ehem, I'm not so versed in Python but I'll check.

I'm aiming for the DLL which are included in the list of packages in
nt/INSTALL.W64, sorry, I can't tell at the moment which ones are
included.

  mingw-w64-x86_64-xpm-nox \
  mingw-w64-x86_64-libtiff \
  mingw-w64-x86_64-giflib \
  mingw-w64-x86_64-libpng \
  mingw-w64-x86_64-libjpeg-turbo \
  mingw-w64-x86_64-librsvg \
  mingw-w64-x86_64-lcms2 \
  mingw-w64-x86_64-jansson \
  mingw-w64-x86_64-libxml2 \
  mingw-w64-x86_64-gnutls \
  mingw-w64-x86_64-zlib \
  mingw-w64-x86_64-harfbuzz

And I guess you are doing this for Emacs-29 and I'm going for 28.0.91,
so e.g.  sqlite3 is not in the portfolio yet. :-)

D'oh. Iʼm sure Iʼve got some reading comprehension lying around here

Have you seen the new language "emoji"? :D (Too sad, Emacs 28 hasn't
learned it..)

What's the codepoint? Iʼm not aware of a language emoji.

Of course it did!  From Emacs 28's fontset.el:

  (set-fontset-font "fontset-default" 'emoji
                                      ^^^^^^
                    '("Noto Color Emoji" . "iso10646-1") nil 'prepend)

Yes and no.

A really brilliant joke is that you can see in etc/HELLO - with Emacs-28
- for the language "emoji" a "WAVING HAND SIGN" icon.

Then I tried a follow-up joke of my own: A simple character emoji ":D"
and claimed that Emacs-28 hasn't learned "emoji".  In Emacs-29 I would
have put in (with C-x 8 e e) a real, graphical emoji.

(Undaunted, I'm trying another one) Can we settle for: Emacs-28 can
"read emoji" and Emacs-29 is able to "speak emoji"?

In emacs 28 if you know the codepoint(s) you can enter them with
'C-x 8 RET <codepoint>' and they'll display properly. The emacs-29 support for
entering them that youʼre talking about will likely be available as a
package for emacs-28 at some point.

Theyʼre all unicode codepoints and emacs versions previous to 28 could
read them fine. The only thing that happened in emacs-28 is that their
display changed :-)

Just to confirm this will just be an omission on be behalf. IIRC,
jannson and harfbuzz are the last two additions to the
dependencies. lcms2, I think, but I remembered to patch the
documentation there.

If I remember correctly, this is because the msys dependency tree is
not totally reliable.

At the time, I was trying hard to decrease the binary
size. Unfortuately, the msys tree is an "at most" dependency rather than
an "at least"; so, it's very easy to find that, again, you've pulled in
half of msys2 which is not the intention.

Hence this skipping.

TLS should work if at all possible. The tests that I have for a
functional windows Emacs (in etc/w32-feature.el) are better than nothing
but don't test whether emacs is working just whether it thinks that it
should be.

"Phil" is my usual. "Phillip" is my actually full name. "Philip" is an
alternative spelling but is not my name.

There's a story behind this, but this is probably not the place.

Thanks so much for confirming it was an omission (not anything
intentional or more complex :)

I'll add jannson and harbuzz to the dep-zip script and (eventually).

The only thing to be ware of here is if you are running
test/src/json-tests.el that you are running them using just the files in
the Emacs package that you are testing. If you run them using the
makefile from inside an msys2 shell, then are likely to be getting the
dependencies from the msys2 shell.

That's why I added w32-feature.el to etc/ so that it ends up in the
install version. Clearly it makes no sense to replicate everything from
json-tests.el in w32-feature.el. But there needs to be something to make
sure that Emacs is using only it's packaged dependencies.

I noticed :P

Locally I've been investigating by comparing results from several
different sources including ProcessExplorer, ldd, ntldd and cygcheck.
(To get recursive checking with ldd I wrote a rather ugly Perl
script.)  Then I'm looking at the documentation from MSYS website
(one-by-one by hand) to figure out which ones are optional.

ACK, and thanks for the nudge on using etc/w32-feature.el to test the
installed versions.

FTR, as I hack on the scripts I've been testing locally running both
scripts then by opening Emacs from the
~/emacs-build/install/emacs-28.0.91/bin folder and then "doing suff".
For example opening a PNG.  Then I check (with ProcessExplorer) that
Emacs is loading (e.g.) libpng16-16.dll from the Emacs bin folder (and
not from the msys bin or some other place).

Firstly:  I'm not too sure yet.  I still need to download the Emacs
27.2 zip from the official source and do a direct "gap" comparison.

Overall, I'm leaning toward ditching automation of dependency
detection in favor of adding a separate file.   All efforts to
automating dependency recursion seem britle, ultimating causing more
work than they save us as we have to track down one mystery after
another. The proposed new file will
 - exhaustively lists each DLL we ship
 - be referenced in by documentation (such as README.W32)
 - be loaded by scripts, e.g. build-dep-zips.py
 - have additional "columns" to name the msys package, and
 - document why the dependency is required.

I have attached a txt file which is the complete list of what I would
start out including in that file.  Obviously, it's missing the msys
package names and has no commentary, so far.   I would probably call
it admin/nt/dist-build/deps.txt but I don't feel strongly about the
filename.

WDYT?

Meanwhile, in mesier news:

I wrote a perl script (also attached but don't bother) to find second
(and etc) order dependances using LDD that I believe should have been
(but have not been) getting pulled into the build.  I thought that the
msys installation folder path change Dieter caught would sort this,
but the numbers seem to don't add up (yet), probably because of the
undependability of the msys dependency checking that you mentioned.

I thought this would get me up to the same count (77) as Dieter reported, but:

  $ ls *.dll | wc -l
  19

  $ perl ../../../find-deps.pl | xargs -I '{}' cp '{}' .
  searched: 19, found: 392, of which 43 are missing in
/c/Users/corwi/emacs-build/install/emacs-28.0.91/bin

  $ ls *.dll | wc -l
  62

Note, these are the 62 DLLs listed in the attached textt file.

I also used this rather henus string of pipelined commands to
"cross-check" for missing dependencies and only came up with one,
which appears to be an optional dependency of harfbuzz:

  $  find ./ -name '*.dll' -print0 | xargs -0 -I '{}' cygcheck '{}'
2>&1 | grep 'could not' | cut -d ' ' -f 6 | sort | uniq
  libicuuc69.dll

Finally, I double-checked using an even more rediculous set of
pipeline commands. seemingly confirming everything the prior finds are
in the bin directory:

  $ find ./ -name '*.dll' -print0 | xargs -0 -I '{}' cygcheck '{}'
2>&1 | grep -v 'could not' | cut -d ' ' -f 6 | sort | uniq | xargs -0
-L1 echo | xargs -0 cygpath | perl -npe 's|c:|/c|g' | xargs -L1
basename | xargs ls >/dev/null

All this has me convinced some DLLs that shipped with Emacs 27.2
aren't findable as dependencies of anything we currently need for
Emacs 28, but not why.  And that leads me to the suggestion, above:  I
think we should hard-code the DLLs along with their source packages.
We can consider automatically generating/updating the deps file once
we get that far.

Warmest regards,
Corwin

With this, we are much closer.   New set is uploaded to the
with-native-compilation folder in the usual Not Sure If We Are Ready
For Prime Time location[1].

This version has 62 DLLs as were listed in the txt file attached to my
recent reply to to Phil in this same thread.  I still need to review
those against the 77 you reported from 27.2 but that's not going to be
tonight.

Meanwhile, I tested these (using the zip with deps version) on kiddos
gaming rig and verified that the tests from w32-feature pass,
package-refresh-package works, and various types of image load.  I
also checked with ProcessExplorer that I'm not loading DLLs except
those provided with the dist and those under some windows/system path.

As an interesting aside:  I see that it *is* loading the natively
compiled sources that were build and packaged with Emacs.  This is
despite getting a nil return from `native-comp-avialable-p', which
suggests that even people without a local libgccjit+gcc (e.g. a
working MSYS) can benefit from (the bundled) nativly compiled sources
we distribute.  [[stroking chin myscheviously]]

Please let me know if you think these are ready to push to alpha.

Attached are dffs for admin/nt/dist-build thus far.

Yes, I compared your list of dependencies with the "nice-to-have" list
suggested in nt/INSTALL.W64 and these are all there - in your
script. :-)

Thank you

        Dieter

We had an issue with a missing libgmp-10.dll on computers without MSYS2,
though. So Corwin added it as an additional dependency.  I read that
this library should not be strictily necessary for Emacs to run - there
should be some inbuild fallback method available.

I suspect on OUR MSYS systems the gmp library is present and then
configure is setting up our builds to expect this presence on all
machines..

I can suggest a way to find all the actual dependencies of a set of
*.exe programs and DLLs by using only the standard tools, and
is thus very reliable.  The command to use is this:

  objdump -p *.exe *.dll | fgrep "DLL Name:" | gawk " {print $3, $4, $5}" | sort -u

Run this in the 'bin/' directory where you have executable programs
and DLLs, and it will show a sorted list of all the DLLs needed by
those programs and DLLs.  You will need to recognize and ignore any
system DLLs, such as msvcrt.dll, KERNEL32.dll, USER32.dll, WS2_32.dll
etc. in the list; for the rest, make sure every one of them is in the
same 'bin/' directory.  Each time you add some DLL to the 'bin/'
directory, re-run the above command again, because adding DLLs can
potentially add dependencies.  Repeat this process until all the DLLs
shown by the command are in the same directory: then you are done.

Óscar Fuentes said there were no changes in the layout lately, I assume

INSTALL.W64)

Thanks, I had a look.  Before I forget - just in case - only stuff in
"with-native-compilation" is updated!  But I guess you'll upload only
"with-native-compilation" anyway. :-)

Please see in the attached file a comparison of Arash Esbati's (thanks
again), mine and your list of DLLs.  And it looks reasonable to me. 

I'm afraid we can't compare 27.2 builds from Phil's setup one on 1 with
our 28 builds.

Very good, thank you kiddos! :-)

As far as I understood, this is exactly what Eli hoped for.

Such systems can't natively compile stuff but benefit from available
.eln files. :-)

Please push.

Except others, with more experience, want to chime in..

This is the expected behavior.  Only native-compilation of *.el files
for which no *.eln files are provided is disabled without libgccjit
and Binutils installation.  Loading of existing *.eln files doesn't
need libgccjit.

So I'm not sure why you are surprised.

IIUC it's not necessary for Emacs, but it's necessary for libgnutls.

Now that ask, I'm not sure either.

Should we consider adding NATIVE_FULL_AOT when building the windows
distribution?

You could, but that still means users cannot modify the *.el files and
get them recompiled.

Whether NATIVE_FULL_AOT is worth is: it is yet to be determined.  I
tend to think we should provide a default build, and only use
NATIVE_FULL_AOT if other platforms do that (which will not happen
before Emacs 28 is released and we collect feedback from users and
downstream distributions).

What you say makes perfect sense.

FWIW, I have been using NATIVE_FULL_AOT with self-built emacs-28 as my
daily drive for around four months.  An instance of this is nearly
always running ERC.  I've been quite happy.

Let's go without NATIVE_FULL_AOT, for at least pre-release 1.

I will push what I have to the FTP site after work today.,
notwithstanding reports of (further) critical defects.

I was clearly keen to get something reasonable automatic as the list may
change over time. Although, as I always used the same dependencies for
an entire main release of Emacs, having something manual would be possible.

I used to set up the .emacs on my build machine to automatically run
w32-feature.el on start up which was a great time saver!

Indeed; it would be good to get a bit more of this kind of thing into
w32-feature.

I think it sounds sensible, but there is a big unknown. The list of DLLs
that Emacs depends on is not very big and it does not change very much
(I think three or four new ones in the time that I did the build). So,
the question is, how much change will there be in the list of indirect
dependencies; that is partly in the hands of the developers of the
libraries we depend on and partly in the hands of MSYS2. And it also
depends on whether you want to update or check for just minor releases
or just major ones.

My guess would be that this will be managable and that you are unlikely
to find a lot of noise in the process, but it is just a guess.

Personally, I'd just bundle the list as a string in a python script. Why
parse something that you don't have to?

Thanks for w32-feature.el just ran your tests successfully with the
latest build of Corwin.  Now I'll have a look on json-tests.el.

Please tell me why you didn't put w32-feature.el in the test/src/
folder?

I'm pretty sure the tests aren't shipped with Emacs, while the etc
folder is.  The header comments say this is expected to be available
for end-users to see if features may be missing under Windows.

FWIW, I'll just (re)mention that I think `w32-feature.el` should be made
to work on non-w32 systems and then moved to `lisp`.

From a cursory glance I can't see code which might be restricted to
Windows or "w32" systems, except the naming.  Just ran the tests of
w32-features.el on:

GNU Emacs 28.0.91 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.30,
cairo version 1.15.10) of 2022-01-14

And the result is as expected for my (default) configuration:

  Selector: t
  Passed:  13
  Failed:  3 (3 unexpected)
  Skipped: 0
  Total:   16/16

  Started at:   2022-02-06 18:05:36+0100
  Finished.

  ...F.F...F......

      (ert-test-failed
       ((should
         (eq 'harfbuzz
              (car

        :form

Please tell me what else do you expect from w32-feature.el, maybe
extensive build information for any platform? :-)

Something like that, yes.  But mostly change the output such that
missing features (or different compilation options) aren't all displayed
as scary test errors but with a more informational tone, I guess.

From the old thread and your remarks it seems to me that this "feature"
library should fulfil two aims: Testing features when building Emacs
distros (especially under Windows) and providing information for users
without the complete source tree.

I took up the idea from Alan Third and completed some missing "standard"
features (from nt/INSTALL.W64):

  (defun insert-feature (description test)
    (indent-to 2)
    (insert (if test "✔" "✖"))
    (indent-to 5)
    (insert description)
    (insert "\n"))

  ;; feature list from nt/INSTALL.W64 
  (defun list-features ()
    (interactive)
    (switch-to-buffer
     (get-buffer-create "*Features*"))
    (read-only-mode -1)
    (erase-buffer)
    (insert "Standard Emacs Features:\n")

    ;; harfbuzz
    (insert-feature "Harfbuzz - text shaping library "
                    (eq 'harfbuzz 
                        (car (frame-parameter nil 'font-backend))))
    ;; zlib
    (insert-feature "Zlib - compression library" (zlib-available-p))
    ;; libxml
    (insert-feature "xml2 - parser library" (libxml-available-p))
    ;; lcms lcms2-available-p
    (insert-feature "lcms2 - color translator library" (image-type-available-p 'pbm))
    (insert-feature "JSON - data exchange library"
                    (progn (require 'json) (fboundp 'json-serialize)))
    (insert-feature "GNUTLS - secure communication library" (gnutls-available-p))
    (insert-feature "pbm - image library" (image-type-available-p 'pbm))
    (insert-feature "xpm - image library" (image-type-available-p 'xpm))
    (insert-feature "bmp - image library" (image-type-available-p 'bmp))
    (insert-feature "gif - image library" (image-type-available-p 'gif))
    (insert-feature "png - image library" (image-type-available-p 'png))
    (insert-feature "xpm - image library" (image-type-available-p 'xpm))
    (insert-feature "jpeg - image library" (image-type-available-p 'jpeg))
    (insert-feature "tiff - image library" (image-type-available-p 'tiff))
    (insert-feature "svg - image library" (image-type-available-p 'svg))
    (insert-feature "native images" (image-type-available-p 'native-image))
    ;; what are native images?
    ;; jansson = json?
    ;; thread support?
    ;; modules
    ;; gmp <- gnutls
    (read-only-mode 1))


What do you think?

By the way, please tell me what are native images?

This is looking good!  I have a few suggestions but not all will
likely interest you.

I wonder if it would be worth separating the name from the rest of the
description?  This could make the output even prettier.

in a similar vein, I think tabulated list mode could be a good fit for
this.  For the sake of argument, let's suppose the tests are moved to
an var, something like:

(defcustom list-features-list
  '((name:"Zlib"
    description:"compression library"
    test: zlib-available-p)
    ;; ... and so on
  )
  "List of optional Emacs features.

This is used by `list-features', which see.")

At this point `list-features' only has to walk the last transforming
the function to results to become suitable for use as a
"tabulated-list-entries function".

As a bonus, the "testable features list" could enable users to
customize which features should usually be tested/listed, for example
to add non-standard features (as long as they have a test in mind for
them), and to remove things they don't typically care out about per in
their own uses

Even aside putting the tests into a var, I think the sortable
header-line approach taken by tabulated-list-mode could make
`list-features' nicely consistent with, e.g. `list-processes.

I think we only get jason-parse-string if jannson is available, so:
  (functionp 'json-parse-string)

Not sure on this one, but I suspect we might be able to use:
  (functionp 'make-thread)

Pretty sure this is just
  (gnutls-available-p)

*I* think `list-features' is going to be very nice to have.

Please & thank you!

If only. On GNU/Linux 'font-backend will return something like
'(ftcrhb x) or '(fthb x) or '(xfthb x). Although adding a
`harfbuzz-available-p' function could be done.

Itʼs using the platform native image APIs rather than libjpeg etc. I

When trying above iterative approach, I just find libgmp and after
adding libgmp-10.dll to the folder there are no further dependencies to
see!?

The dependency on the optional DLLs is implicit, because Emacs loads
them dynamically at run time.  You need to place the DLLs mentioned in
dynamic-library-alist defined in w32-win.el in the bin/ directory, and
_then_ repeat the process.  That's because we are talking about the
dependencies of those dynamically-loaded DLLs.

I see, thank you for this concrete recipe.

I'm a bit baffled, why is in dynamic-library-alist no harfbuzz but
gccjit, gdiplus and shlwapi are there which seem not to be included in
the list of mingw packages mentioned in README.W64?

Are gdiplus and shlwapi somehow missing in the current Emacs Windows

I think they are provided by MS-Windows itself, so you don't need to
package them with Emacs.

Best, Arash

Sorry, forgot about harfbuzz.  We load that one by name.  (I can
explain why, but I don't think it's relevant to this discussion.)  The
name is fixed: libharfbuzz-0.dll.

> but gccjit, gdiplus and shlwapi are there

Ignore gdiplus and shlwapi, they are system libraries that you don't
need (and cannot, for obvious legal reasons) provide in the binary
package.  The reasons they are there are historical, and again
irrelevant.

Right, found the DLLs in a Windows system folder. :-)

Don't worry, I only hoped that dynamic-library-alist might be the only
"source of truth".  OK, so we also need take care of libharfbuzz-0.dll.

Furthermore, it seems that your recipe and can save about 10 DLLs in
comparison to the build-dep-zips.py approach (So far I tested this only
with etc/w32-feature.el).

It's drawback is that such an iterative approach is painful to do by
hand.  I'd like to do this in a script and call below MinGW64 command
from within Emacs

  objdump.exe -p *.exe *.dll| fgrep DLL

My idea is to do something like the following:

  (let ((Objdump-buffer (get-buffer-create "*objdump*"))
        (Bin-folder "~/emacs-build/build/emacs-28.0.91/bin/")
        (Objdump "d:/appl/MSYS2/mingw64/bin/objdump.exe"))
    (setq default-directory Bin-folder)
    (with-current-buffer Objdump-buffer
      ;;(goto-char (point-min))
      (erase-buffer)
      (shell-command (concat Objdump " -p *.exe *.dll") Objdump-buffer)
      (keep-lines "	DLL Name:")
      ;; And then filtering steps
      ;; Iteratively copying files into the Bin-folder..
      
Which brings output into the Objdump-buffer but I'm not sure if above
approach might miss the - possibly - necessary MinGW64 environment
information, don't know if it makes a difference when objdump.exe is
called from the MinGW64 shell or with shell-command .  How would you
bring the output of objdump into Emacs?

It seems to me that all MSYS DLLs on which Emacs depends have a name
component "lib", whereas the Windows libraries have no such substring.
(So I can easily filter them out.)

Thank you very much

First, no need to hard-code the location of objdump.exe:
executable-find should be able to find it.

Second, you change the default-directory in the wrong buffer, I think.

More importantly, I don't see where you have the list of all the DLLs
that Emacs loads.  You need to start from that list.

I don't think I follow your fears here.  What exactly did you think
could go wrong?  What do you mean by "necessary MinGW64 environment
information"?

> How would you bring the output of objdump into Emacs?

shell-command accepts an optional argument to that effect.

There are exceptions: zlib1.dll.  For now, it's the only exception
AFAIK, but watch out for others.

I thought, maybe, a call to objdump.exe needs further environment
information than Emacs is providing..

Luckily zlib1.dll contains also "lib". :-)

In the following I'm using copy-file. But I'm wondering why the argument
OK-IF-ALREADY-EXISTS can't be used to skip a copy process if the file
exists?  In the following some files will be multiple times overwritten..

Here's a further attempt (and it seems to work for me):

  (defun Copy-dll ( Dll)
    (let ((Build-folder "~/emacs-build/build/emacs-28.0.91/bin/")
          (Exists (file-exists-p Dll)))
      (if Exists
          (copy-file Dll Build-folder 'overwrite)
        (message (concat "[Info] Can't find " Dll)))))

  (let ((Objdump-buffer (get-buffer-create "*objdump*"))
        (Build-folder "~/emacs-build/build/emacs-28.0.91/bin/")
        (Dll-folder "d:/appl/MSYS2/mingw64/bin/")
        (Objdump (executable-find "objdump.exe")) ;mingw64 is in PATH
        ;; starting dependency list from dynamic-library-alist
        (Dependencies (add-to-list
                       'dynamic-library-alist

        (Build-deps)		 ; current dlls in the build folder
        (Dll nil)) ; temp variable

    ;; prepare (flatten) dependency list

You are relying on luck too much: look in your Windows/system32
directory, and you will see there quite a few system DLLs that match
"lib".  My suggestion is to have an explicit list of system DLLs that
should be filtered out.

I'm not sure I understand, but you should stop copying when you find
the first existing DLL for each feature in dynamic-library-alist.  We
arrange the DLLs there in the descending order of
versions/importance/quality, so the leftmost DLL that is found is
always the best, and should not be overwritten by any existing DLLs
for the same feature whose names are to the right of that.  For
example:

     '(tiff "libtiff-5.dll" "libtiff3.dll" "libtiff.dll")

If you find libtiff-5.dll, you should not overwrite it with
libtiff3.dll, even if the latter exists.

Also, I don't see that you ignore DLLs that don't match the version
with which Emacs was compiled.  E.g., this part of
dynamic-library-alist:

       (if (>= libgif-version 50100)
	   ;; Yes, giflib 5.0 uses 6 as the major version of the API,
	   ;; and giflib 5.1 uses 7, thus "libgif-7.dll" and
	   ;; "libgif-6.dll" below (giflib 4.x used 5 as the major API
	   ;; version).  giflib5.dll is from the lua-files project,
	   ;; and gif.dll is from luapower.
	   '(gif "libgif-7.dll")
	 (if (>= libgif-version 50000)
	     '(gif "libgif-6.dll" "giflib5.dll" "gif.dll")
	 '(gif "libgif-5.dll" "giflib4.dll" "libungif4.dll" "libungif.dll")))

means that Emacs compiled against giflib 5.1 and later should not try
to use libgif-6.dll or libgif-5.dll, it should only use libgif-7.dll.
We do this when a newer version is binary incompatible with an older
one, so you cannot just choose whichever DLL you have, you must use
the one that is binary-compatible with Emacs.

Thanks.

I understand, thanks.  I'll grab all DLL filenames of the
Windows/system32 folder and filter them out.  Or how would you build or
hard-code such a filter list?

>> In the following I'm using copy-file. But I'm wondering why the argument

Would it make sense to you to have the (additonal) capability for
copy-file to do nothing if the target file already exists?

At the moment I can 1) trigger an error, 2) overwrite an existing file
and 3) ask for confirmation either to overwrite or to have an error.  So
3) is actually only an - annoying - way to have 1) or 2), there's no way
to leave an existing file alone without an error.

And here's another thing I stumbled over: An excerpt of copy-file's
documentation string:

  OK-IF-ALREADY-EXISTS is an integer, request confirmation from the user
  about overwriting; this is what happens in interactive use with M-x.

The interactive part in the documentation is unnecessary, I think, the
request happens for me in batch mode as well.

Actually my code was copying all of above tiff DLLs to the bin
folder.

I see, I'll just copy the available, leftmost DLLs.

Please tell me where I can find above definition of
dynamic-library-alist?  Mine (Emacs-27.2) just says:

  dynamic-library-alist is a variable defined in ‘C source code’.

  ((harfbuzz "libharfbuzz-0.dll")
   (gdiplus "gdiplus.dll")
   (shlwapi "shlwapi.dll")
   (xpm "libxpm.dll" "xpm4.dll" "libXpm-nox4.dll")
   (png "libpng16.dll" "libpng16-16.dll")
   (tiff "libtiff-5.dll" "libtiff3.dll" "libtiff.dll")
   (jpeg "libjpeg-8.dll")
   (gif "libgif-7.dll")
   (svg "librsvg-2-2.dll")
   (webp "libwebp-7.dll" "libwebp.dll")
   (sqlite3 "libsqlite3-0.dll")
   (gdk-pixbuf "libgdk_pixbuf-2.0-0.dll")
   (glib "libglib-2.0-0.dll")

   (gnutls "libgnutls-30.dll")
   (libxml2 "libxml2-2.dll" "libxml2.dll")
   (zlib "zlib1.dll" "libz-1.dll")
   (lcms2 "liblcms2-2.dll")
   (json "libjansson-4.dll")
   (gccjit "libgccjit-0.dll"))

I'm struggling to understand that, I thought ./configure would sort out
what is necessary and available on my system?

Thank you for your interest

I'd maintain a hand-crafted list.  There aren't so many system DLLs
you will see in the dependencies.

I guess you took this from a running Emacs?  The original is in
w32-win.el, and that's where I took the fragment I've shown.

If you intend to collect the dependencies by running the same Emacs
binary as the one you will be packaging, then using the list from the
running Emacs will solve you the versions problem, because Emacs
filters it to have the DLLs it needs.

Not configure, but Emacs itself when it starts up.
