Good to see that you've included the bzr revno in the filename.

Thanks.

Just a question why in your emacs built, the image used in the splashscreen is 
splash.xpm and in the previous Sean's builts splash.png is displayed?

IMHO, splash.png is much smoother than splash.xpm.

What does this display?

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

If it says "nil", then Emacs cannot display PNG images.  This could
happen if either this binary is built without PNG support (unlikely),
or the PNG libraries you have don't match the version against which
Christoph linked these binaries.  To test the latter hypothesis, type

  C-h v libpng-version RET

and see if it matches the version of libpng DLL you have installed.

libpng-version's value is 10237

I have libpng14-14.dll, and it worked with Sean's emacs builts made
one month ago.
Are there newer libpng files?

Thanks.

Re: emacs-20111018-r106127 Windows Binaries

[Seweryn Kokot]

To be more specific.

I copied the lib14-14.dll and zlib.dll files from the last Sean's
devel built to the new Christoph's built bin/ directory.

Sean's built:
M-: (image-type-available-p 'png) RET
t
C-h v libpng-version RET
libpng-version's value is 10403

Christoph's built:
M-: (image-type-available-p 'png) RET
nil
C-h v libpng-version RET
libpng-version's value is 10237

However those libpng-version numbers do not tell me much.

Any idea?

This means Sean's binary was compiled with libpng v1.4.3

And this means that Christoph built his binary with libpng 1.2.37,
which is _older_ than 1.4.x.  So Christoph's binary refuses to work
with the new version of libpng you have, because versions before and
after 1.4.0 are binary incompatible.

To fix this for the binary you have, download libpng version that is
1.2.x and put the DLL in the same place where you have
libpng14-14.dll.

Christoph, to prevent such problems in the future, please build next
binaries with a newer version of libpng.  (nt/INSTALL tells you where
to find them.)

Ok, thanks Eli. Now I see the problem.

I read somewhere that for the current devel emacs, libpng 1.4 or later
is required. So I will wait for the new binaries compiled against
libpng14.

P.S. libpng14-14.dll and zlib1.dll are available at
http://www.gtk.org/download/win32.php

Not required, _recommended_.

Yes. That is correct. I apologize.

I updated my libpng to 1.4.3-1 from the GTK website.

I will check my other library versions tonight make sure to use the
correct versions. Are there any other problematic lib versions you are
aware of?

Seweryn, 
I am planning on building a new weekly snapshot tonight, which should
have to problem corrected. Sorry for the inconvenience.

Ok.

I read it in emacs-24.0.90/README.W32 file which is published with the
emacs binaries (both pretest and current trunk):

It says:

* Image support
...
      PNG: requires the PNG reference library 1.4 or later, which will
      be named libpng14.dll or libpng14-14.dll.  LibPNG requires zlib,
      which should come from the same source as you got libpng.
      Starting with Emacs 23.3, the precompiled Emacs binaries are
      built with libpng 1.4.x and later, and are incompatible with
      earlier versions of libpng DLLs.  So if you have libpng 1.2.x,
      the PNG support will not work, and you will have to download
      newer versions.
...

Anyway for the future it would be good to compile emacs sources with
libpng14. Thanks.

No problem!
Thank you very much for providing windows binaries, Christoph :)

Thank you Christoph. I confirm that it now opens png files using
libpng14-14.dll.

P.S. So far I have followed emacs.devel mailinglist on gmane here:
http://news.gmane.org/gmane.emacs.devel/
However, now I see that gmane does not show all posts/emails. For
example there is no anouncement of the new binaries on gmane and all
the posts in this thread are only available in lists.gnu.org/archive
and not on gmane:
http://lists.gnu.org/archive/html/emacs-devel/2011-10/threads.html
Is it a known issue?

You can ask on gmane.discuss; I have not missed any posts and I use a
real NNTP reader, not the web interface.

The first post in this thread, for instance, is at
