netpbm and uncompface have in fact nothing to do with it, Xfaces work in
GNU Emacs without these packages installed, and without the icontopbm and
uncompface executables in the path.

So the winner is libpng. Turns out only 1.2.44 works. Any later version,
including the current 1.5.0 doesn't work with GNU Emacs and Emacs just
shows empty boxes instead of the X-Face.

This sounds like an Emacs bug, and you should report it with `M-x report-emacs-bug'.

Gnus displays/doesn't display X-face, why?

[JJ]

I know this is more of an Emacs compilation question, but thought maybe
it'd be more appropriate here, since it relates only to Gnus.

I can't compile Emacs to display the X-face in Gnus anymore.

I'm using latest checkout No Gnus, am compiling GNU Emacs latest bzr
checkout.

The latest version I've compiled that displays the X-face was 100410,
after that all the versions I'm compiling, I get just a box for - empty
frame instead of the X-face displayed in the message header in Gnus.
Sometimes the lines around the not-displayed X-face flicker a bit
noticeably, and I have to exit Gnus after displaying such a message since
it's stuck somehow.

When I start the old compiled Emacs, it displays the X-face properly in
the message, this is with the same .emacs, so it's not a config issue.

I have compface and netpbm so it shouldn't be a problem with them.

It's not a question of Emacs version, as just now I went back and
recompiled the 100410 and sure enough it doesn't display the X-face, so it
must've been something I had set up at compilation time then that's
changed, but don't know which.

Thought it was maybe ImageMagick associated but I didn't have ImageMagick
available when compiling it then, and even now if I have it or don't have
it installed during compilation, doesn't make a difference... and
gnus-article-x-face-command is set to `gnus-display-x-face-in-from' - the
default, not changed via config, so it's not calling imagemagick.

I'm out of ideas, what the hell could it be? The reason it's important is
I need to compile Emacs now for a different PC and can't compile it so
that Gnus then shows the X-face, so it's not a PC architecture thing, I'm
overlooking some requirements during configure but not sure what.

Anyone have an idea?

Thanks a lot for any help.

Looking at the code, it looks like it's calling icontopbm and
uncompface.

So I thought as well when inspecting the code. However it turns out these
two aren't needed, in fact works fine on a system without them.

After intense experimentation determined it's either one of these that's
causing the problems:

libgif
libtiff
libpng
libxpm
libjpeg

I compiled all of these myself and wasn't working when linked against
them. When linked against Debian/Ubuntu versions of these it works, so one
of these it is, I'll try to recompile in steps to determine the sucker,
but it doesn't bother me greatly now.

By a far shot, it could also be gcc 4.5.1 since I also removed the self
compiled one and compiled with 4.4.5 just to make sure, but I think it's
one of the libs.
