Subject: 25.1; cannot display JPEG image
Date: Sun, 25 Sep 2016 11:45:11 +0900

I installed emacs-25.1-i686-w64-mingw32.zip and
copied libjpeg-9.dll and libgif-7.dll into emacs bin directory.

JPEG images are not displayed in emacs buffer,
while GIF images are displayed.

Emacs says "Cannot display image: (Invalid image specification)".

DLLs are obtained from http://sourceforge.net/projects/ezwinports/files/,
archived in jpeg-v9a-w32-bin.zip and giflib-5.1.0-w32-bin.zip.

Ouch! what a mess!

It looks like the MinGW64 project doesn't yet offer a build of
libjpeg-9.dll, so the Emacs binary you have was compiled against
libjpeg-8.dll, and Emacs wants it.  But the ezwinports site only has
the later libjpeg-9.dll, so Emacs refuses to use it (because they are
binary-incompatible).

For now, you will be better off using the DLLs from here:

  http://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-25-i686-deps.zip

(Btw, Phillip: why on alpha.gnu? why not ftp.gnu.org, right next to
the Emacs binaries?)

I will try to upload the older libjpeg-8.dll to the ezwinports site
when I have time, so that users of the official binaries could get it
there as well.

A similar problem is with libgnutls-30.dll, except that there, MinGW64
is ahead of ezwinports.  I will try to port and upload the newer
version soon.

Sorry.

It's there now, look for jpeg-v8d-w32-bin.zip.

I downloaded jpeg-v8d-w32-bin.zip and installed libjpeg-8.dll.
Now I can view JPEG images. Thank you.

Great, thanks for testing.

Gnutls 3.4 will take a bit more time, as it needs dependencies.  I
will try to do this during the next few days.

Done now, and uploaded.  Look for gnutls-3.4.15-w32-bin.zip.

With this accomplished, I consider this bug done.

Thanks.
