Bug#443032: Patch to enable the pixman package
Synx
latest ABI, so I went and compiled it myself, fixed the problems that
were stopping it from compiling. pixman (whatever that is) is a
pkg-config package in the new xorg system, so anything that uses it (aka
wacom-tools) has to do the pkg-config niceties in the configuration and
makefiles. Also if we're using it we should depend on libpixman. So
that's what this patch does. I successfully built and installed the
packages after compiling this patch, though someone who knows more about
pixman might be able to minimize those compiler warnings.
After applying the attached patch (-p0) you have to run aclocal,
automake and autoconf again. I didn't want to include auto-generated
output in my patch.

That patch is (mostly) wrong. wacom should indeed use pkg-config to get
the necessary cflags, but it doesn't have to care about pixman.

I'm not sure what this file is for, but this change looks wrong too.

The file linuxwacom/src/xdrv/xf86Wacom.c includes the file xf86.h, which
is part of the xorg package. However down the chain of includes:
In file included from /usr/include/xorg/regionstr.h:53,
from /usr/include/xorg/region.h:51,
from /usr/include/xorg/window.h:52,
from /usr/include/xorg/input.h:55,
from /usr/include/xorg/xf86str.h:38,
from /usr/include/xorg/xf86.h:45,
from xf86Wacom.h:66,
from xf86Wacom.c:71:
/usr/include/xorg/miscstruct.h:54:20: error: pixman.h: No such file or
directory
So wacom does use pixman on one hand. On the other hand,

You're right on there. I realize now that it's a dependancy of xorg,
which is a dependancy of the wacom tools, but pixman is not a direct
dependancy of wacom. Sorry for the trouble. I'll rewrite the patch then,
no problem.

The change adds pixman as a build dependancy. But yeah I'm not sure what
that file is for either. I was just being careful.
And... yeah. This new patch successfully compiles too. Without worrying
about pixman.
