xorg-server: undefined symbols _glProgramEnvParameters4fvEXT _glProgramLocalParameters4fvEXT on Tiger PowerPC

[ryandesign (Ryan Carsten Schmidt)]

I can build xorg-server on Tiger Intel now, but not on Tiger PowerPC:

/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: Undefined symbols:
_glProgramEnvParameters4fvEXT
_glProgramLocalParameters4fvEXT

Attached are the build logs from the two machines. I've tried to minimize the differences between them. I'm not able to tell by diffing them why the PowerPC build fails.

I note xorg-server builds with dbus if it's present (see Intel log).

successful build on Tiger Intel

Can you please try the attached patch?

[dbevans (David B. Evans)]

This patch made no difference that I can see. Still fails as shown above.

[jeremyhu (Jeremy Huddleston Sequoia)]

Can you please do this on both your ppc and intel boxes:

grep GL_EXT_gpu_program_parameters /System/Library/Frameworks/OpenGL.framework/Headers/glext.h  

Actually, if you could attach your /System/Library/Frameworks/OpenGL.framework/Headers/glext.h, that would help a bit.

If the above patch didn't work, it looks like your glext.h is explicitly setting GL_EXT_gpu_program_parameters to 1 even though the symbols are not defined. That is naughty. Perhaps I should make these checks all runtime instead of compile-time... sigh.

[dbevans (David B. Evans)]

Here's the grep output for the ppc case:

devans% grep GL_EXT_gpu_program_parameters /System/Library/Frameworks/OpenGL.framework/Headers/glext.h
#define GL_EXT_gpu_program_parameters       1
#if GL_EXT_gpu_program_parameters
#if GL_EXT_gpu_program_parameters

Full include file is attached

Ryan will have to supply the intel version as I don't have one.

tiger ppc glext.h

[jeremyhu (Jeremy Huddleston Sequoia)]

updated xorg-tiger-ppc.patch

[jeremyhu (Jeremy Huddleston Sequoia)]

Ok, it looks like OpenGL.framework flat out lies to us on Tiger/ppc ... Try the updated patch.

[dbevans (David B. Evans)]

Building .... news at 11.

[dbevans (David B. Evans)]

OK, build completed without error although still see these multiple definition warnins:

Started the server, ran gimp and all seems to work.

On start of the server, the following console warnings appear though (did with earlier versions as well). Is there some configuration missing or is this just noise?

Thanks for the help!

The XKB stuff is just noise.

The multiple definitions are annoying but fine. They're the same code in two places, so as long as the linker finds one of the two, we're fine...
