1 - Using Emacs for Windows
https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-27/emacs-27.1-x86_64.zip
2 - Unzip in C:\Emacs so that the Emacs bin directory is
     C:\emacs\emacs-27.1-x86_64\bin
3 - Exec emacs -Q
4 - Open splash.svg:
     C-x C-f 
C:\emacs\emacs-27.1-x86_64\share\emacs\27.1\etc\images\splash.svg

The image is opened as XML text file (nXML Valid Image) and not rendered as
an image as expected.

Version 26.3 (windows) works ok and splash.svg is rendered as image.

What does the below display in that Emacs, after you start it with
"emacs -Q"?

  M-: (image-type-available-p 'svg) RET

Also, do you have librsvg-2-2.dll in the same directory as emacs.exe,
and if so, what does the dependency walker
(https://www.dependencywalker.com/) say about its dependency DLLs?

Thanks.

Sorry but dependency walker always hangs on my pc, I've tryed both 
version, executed with or without admin privileges, even disabled my av. 
Whenever i open a file it hangs.

I've used another tool : https://github.com/lucasg/Dependencies
The program don't have export function. I can only offer a screenshot.


Let me know if I can do anything else.
Tanks.

That's a clear sign that SVG images aren't supported in this build.

Thanks, the dependencies you show spell out the reason: the
libgio-2.0-0.dll, libglib-2.0-0.dll, and libgobject-2.0-0.dll are
missing from the zip archive.  These are dependencies of librsvg, so
without them SVG will not be supported.

Phillip, could you please look into this?  The missing DLLs should be
added to the bundle.

It turns out that this is not enough.
I copied the three dll from the 26.3 bundle and run the test again:

(image-type-available-p 'svg) => nil

And obviously the svg file is shown as text.

I can make it work only by operating a Frankestein mix between old 26.3
bundle (with deps) and 27.1 bundle (with deps).

Then using the same dependency tool, please look for more missing
DLLs.  There must be others.

I don't understand what that means, sorry.

It probably means unpacking the 26.3 deps bundle over Emacs 27.1, or 
some mixture of the two. As the 26.3 bundle had a lot more dependencies 
that's not a surprise. Specifically, the problem is probably the logic 
in Emacs-27.1 that skips glib2 as a dependency. IIRC, that brings in 
python and many other of the packages from msys2 which made Emacs-26.3 
so huge.

The librsvg dependency itself is correctly given when I build the zips 
package.

I've tried to dig more in the dependencies and found two more missing:
libpcre-1.dll
libgmodule-2.0-0.dll

Copied to the bin directory, but it keep opening splash.svg as a text file.
I can't see any missing dependency.
Have you replicated the bug?

I haven't. I have limited access to a windows machine at the moment. Are 
you sure the file is okay? You said it works with Emacs-26; I presume on 
the same file?

I have double checked it. Same results on splash.svg from Emacs-26 and 
Emacs-27 bundle.
I copied the dll files that where missing come from the Emacs-26 bundle.

Hello Eli,

I've also tested and followed your advice with the dependency walker.
I've found the following missing ddl:
- libffi-7.dll
- libgio-2.0-0.dll
- libglib-2.0-0.dll
- libgmodule-2.0-0.dll
- libgobject-2.0-0.dll
- libpcre-1.dll

don't know why the libffi-7 is needed as there is an libffi-6 in the
directory. But with thoses files I can display SVG images inside emacs.

Pierre

I missed the libffi-7.dll when searching for dependencies.
Now it works for me too.

Tanks.

Pretty sure all of this stems from 61c2183a440. I dropped using pactree 
and used pacman directly to determine dependencies. I also exclude glib2 
as a dependency hence the problem. If I include this, we go back to 
getting python and half the of msys2 included in the download bundle.

I guess for Emacs-27 I should just include glib2 and be exclude so of 
its dependencies (gettext and python probably). The question is whether 
to do this for Emacs-27.1 or 27.2.


For Emacs-28, I think I need a better dependency mechanism than looking 
at msys2, perhaps based around the shell script that was sent earlier, 
or an automated (or horror manual) use of dependency walker.

Thanks.

They are different versions of libffi with incompatible ABI, so
libffi-6 cannot replace libffi-7.

Too bad MSYS2 use such a "maximalistic" approach to dependencies.

Something like that, yes.

I'd prefer 27.1, of course, if you can afford working on this soon
enough.  Because 27.2 is at least a couple of months away.

If you have Binutils installed (which you must, since you build
Emacs), you can find dependencies by recursive application of
objdump.  E.g., the following command will show all the DLLs of all
the binaries in a directory:

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

You need to rerun this each time you add one or more DLLs to the soup,
until all the DLLs you see in the list are present in the directory.

From my user side point of view: just add the missing dll in the archive
for 27.1 and let the dust lay on.

I suggest it  because, if like me, your company has and antivirus
software which block some actions on programs without good reputation
you're lock with officials distributions. Lukly Emacs is on the list
...

see https://whitelist.kaspersky.com/advisor

For example, at my work, writing to
c:/windows/system32/drivers/etc/hosts is forbiden for not known
applications like the ones you're compiling yourself (and trust me this
bother me quite a lot).

If could help you in testing, ask for it.

Okay. So I have uploaded a new version to alpha. It is about 10Mb larger 
than before, and seems to render using harfbuzz and reports 
(image-type-available-t 'svg) as true. The only change is this:


$ git diff
diff --git a/admin/nt/dist-build/build-dep-zips.py 
b/admin/nt/dist-build/build-dep-zips.py
index 0e5f1ae1dc..0f18fe331d 100755
--- a/admin/nt/dist-build/build-dep-zips.py
+++ b/admin/nt/dist-build/build-dep-zips.py

So, we still avoid the mega bloat of python, but do pull in glib2.

I would need to install this patch to Emacs-27. This would mean that the 
Emacs-27 binary with deps version was not strictly build form the 
emacs-27.1, but from a slightly later commit. Not a disaster I think -- 
normally the deps file is built from an early version.

I would plan to release this as "emacs-27.1" given that the previous 
binaries were only every uploaded to alpha and not described as 
"official".
