I built the 1.7.0 release code from source, on 32-bit debian 5.0.4. I used makepanda.py --installer --everything and then used dpkg to install the resulting .deb file.
I’m using the proprietary Nvidia driver, version 185.18.14, which is slightly out of date, but I don’t think that’s the problem (I’ll upgrade to the latest when I get a chance). My video card is a GeForce 7300 LE (OpenGL version 2.1.2).
GLSL Shaders work fine using other libraries. And Panda3d shows they’re supported (I haven’t actually tried one yet). According to glxinfo, GL_ARB_fragment_program, GL_ARB_fragment_program_shadow, and GL_ARB_vertex_program are all supported (as are their NV equivalents)…I’m guessing those are what are needed for “Basic shader” support.
HAVE_CG isn’t defined during the build, so (AFAICT) the block of code in glGraphicsStateGuardian_src.cxx that would check to see whether my card supports Cg is getting preprocessed away.
When I built it originally, I did not have nvidia’s Cg toolkit installed (I was clued in by a “WARNING: Could not locate thirdparty package …” message). I installed it, wiped my built directory, and tried to rebuild. The message about the missing thirdparty Cg package went away, but that macro still isn’t getting defined.
After that, I tried makepanda --nothing to be sure the dependency cache is gone, then rebuilt with --everything --installer. Same result.
I can live without Cg shaders, but I’d really like to be able to use Panda’s auto-generated shaders (those would be a huge selling point when I get around to showing a demo).
I imagine using the pre-built binary would fix the problem, but not being able to build from source would be a show-stopper for my boss.
I’m out of ideas, so I figured I’d check to see if anyone here has any suggestions about what I might be missing.
Thanks in advance,
