No rule to make target `../lib/ignore-value.h'

No rule to make target `../lib/ignore-value.h'

[martin rudalics]

The "old way" of bootstrapping trunk on Windows currently fails here as

make[3]: Leaving directory `c:/emacs/quickfixes/src'
make[3]: *** No rule to make target `../lib/ignore-value.h', needed by `oo/i386/emacs.o'.  Stop.
make[2]: *** [bootstrap-temacs-CMD] Error 2

make[1]: *** [bootstrap-temacs] Error 2
make[1]: Leaving directory `c:/emacs/quickfixes/src'
make: *** [bootstrap-gmake] Error 2

Any chance to get this fixed?

Thanks, martin

I've removed the dependencies on lib/ignore-value.h, which no longer
exists, but the patch is totally untested, so caveat builder.

BTW, I *strongly* recommend you switch to the MSYS build procedure.

Thank you.  Unfortunately, it now cracks as

As soon as I understand what side-effects installing MSYS can have, I'll
do that.

Hm. There have been changes to cl-loaddefs which have not been ported
to the old configure.bat build. I wouldn't bet on this being fixed
soonish, because I don't think anyone is really interested in
maintaining it anymore.

MSYS is not added to the path, and most other things you need can be
installed quite self-contained, so there should not be any
side-effects. You invoke the MSYS build through a .bat script that
sets up the required path and runs bash.

Or, if you dislike bash, you can define an alias or .BAT script to run
it and pass it commands via -c. That's what I do.

And how does it find sed.exe for example?

If you follow the instructions in nt/INSTALL.MSYS, many tools are
installed in C:/MinGW/msys/1.0/bin (or wherever you decided to install
MSYS), and the MSYS.BAT script in C:/MinGW/msys/1.0 already sets that
directory in the path.

Additional tools can be installed wherever you want, and you can
create a %HOME%/.profile or %HOME%/.bash_login and set the path there,
so it is only used by bash.

Getting it all installed and according to your tastes is a bit
tedious, but quite straightforward.

Then we should remove the configure.bat stuff, no?
That will make for one less thing to worry about
while hacking on the build procedure.

I wouldn't oppose, but, OOH, that no one is really willing to maintain
the configure.bat build procedure now does not mean that someone could
not step in. The new procedure does not support building with MSVC,
for example. OTOH, setting up the MSYS build procedure is somewhat
more complex, so removing the old one so soon seems a bit rushed.

Of course, both are moot points if the old procedure does not work.

IMO we should strongly discourage anyone from doing that. Unless they
want to take total responsibility for it, so that no-one else ever has
to touch it again. It has always been a PITA to have to edit those
makefile.w32-in things. I hope they go away Real Soon.

FWIW, I agree. But the MSYS building procedure isn't yet two months
old. Seems too soon IMO.

Why? It's the development version, things change. The sooner the old
method goes away, the more testing the new method will get.

(It seems that many MS Windows users just sit there and get spoon-fed
pre-built binaries anyway. ;) )

It is IMO much easier simply to use a dedicated shell window for
MSYS.  When you install MSYS, it creates a desktop shortcut that opens
such a window, in which everything is already set up.  There's no need
for any batch file.  At least this is how I use MSYS.

        * emacs-lisp/cl-loaddefs.el: Don't version-control any more.

this seems to have an impact, as it is currently impossible to build
the trunk with the old method because of a cl-related issue.

MSYS sets its own PATH, through which it finds its own Sed.

I think we're talking about the same thing, ../msys/1.0/msys.bat.

> At least this is how I use MSYS.

I've settled in using an alias than runs "sh.exe --login -i -c", but I
wouldn't recommend my method to anyone. Not that it has drawbacks (it
hasn't, as far as I can see), but it is very much tailored to how I
like to work.

Eventually, yes.  But not yet, I think.  It's too soon.  People who
use the Microsoft compiler, for example, will have hard time building
Emacs any other way.

We don't worry about that anymore.  We let people who still use it
worry about that (or switch to the Posix build).

How do you discourage volunteers from scratching their itches?  (Not
that we have them queuing up for the job in this case.)

We are already there: no one touches those files unless they want to.
But you need to give people time to realize that these files are no
longer maintained and step in if they want.  It's not like the fact of
their deprecation was announced in the media.  No harm will be done if
we keep the files a little bit longer.  They are just lying there
collecting dust, that's all.

Doesn't bootstrap produce cl-loaddefs?

I never run that batch file.  It isn't needed.

Yes, it does. The bootstrap still fails, though. Perhaps it is not
related to cl-loaddefs existing, because the break up very
specifically is caused by cl-member

  In toplevel form:

etc, which already gives warnings during the POSIX bootstrap (bug#14831).

It's as easy to restore a removed file as it is to remove it.  One can
even do that and keep the original file ID, so the history is intact.

I was being flippant.
Obviously, we can discourage things by stating that they are discouraged.
No, we cannot stop people forking Emacs and doing whatever they want
with the build system, but "we" can make policy decisions and say "no
thanks, we do not want that code in Emacs".

I don't see any compelling reasons for such drastic measures, as long
as these files don't draw any energy from us.  Let time show if they
can be removed sooner rather than later.  We just got a pretty good
test case, in that Emacs no longer builds with those files.  Let's see
if someone gets motivated enough to take over them.

I think there are lots more important things people could spend their

Obviously not, and neither automake.  According to INSTALL.MSYS I did

   After that, use "mingw-get install PACKAGE" to install the following
   additional packages:

    . msys-base
    . mingw-developer-toolkit

   (We recommend that you refrain from installing the MSYS Texinfo
   package, which is part of msys-base, because it might produce mixed
   EOL format when installing Info files.  Instead, install the MinGW
   port of Texinfo, see the ezwinports URL below.  To uninstall the
   MSYS Texinfo, after installing it as part of msys-base, invoke the
   command "mingw-get remove msys-texinfo".)

   At this point, you should be ready to configure and build Emacs in
   its basic configuration.  Skip to the "Generating the configure
   script" section for the build instructions.

So maybe autoconf and automake should be mentioned there?

And clearly

Checking for autoconf (need at least version 2.65)...
ok
Checking for automake (need at least version 1.11)...
ok

is not very reassuring when these are apparently missing.

Anything else I might have forgotten given that I follwed the mingw-get
path?

Thanks for the advice, martin

They are mentioned in the "*** MSYS" section:

   . Additional packages (needed only if building from the Bazaar
     repository): Automake and Autoconf.  They are available from
     here:

       http://sourceforge.net/projects/ezwinports/files/automake-1.11.6-msys-bin.zip/download
       http://sourceforge.net/projects/ezwinports/files/autoconf-2.65-msys-bin.zip/download


In general, I would recommend reading INSTALL.MSYS thoroughly a couple
of times before trying to set up your build environment. Also, I think
it's best to follow the advice in "Installing MinGW and MSYS manually"
instead of using mingw-get

If you install them in another location and then add the dir to PATH,
make will be able to find them, but perl will not be able to find the
Perl packages because they are outside its (Perl's) usual library
structure. That could be fixed by telling Perl where to find them, but
it's not worth it, and other tools would suffer similar problems. It's
better to stick to installing MSYS tools in the MSYS tree.

> Anything else I might have forgotten given that I follwed the mingw-get

Again, from INSTALL.MSYS:

   . Additional packages listed below, from the MSYS Extension
     distribution here:

     https://sourceforge.net/projects/mingw/files/MSYS/Extension/

      - flex
      - bison
      - m4
      - perl
      - mktemp

     These should only be needed if you intend to build development
     versions of Emacs from the Bazaar repository.

Also texinfo.
