When running current svn under Linux with r300 mesa driver from git and without libtxc-dxtn I get these GL errors:

Wrote settings.cfg

The game seems to run fine however. Let me know if you need more info (gdb bt on error or else). The errors happens because I have not libtxc-dxtn.

Yeah, that's expected.

So it's something needing a fix? It also prints this while playing:

Mesa: User error: GL_INVALID_ENUM in glCompressedTexImage2D(internalFormat)
gloadtile_cached: bglCompressedTexImage2DARB failed  (glerr=500)
Error: glGetTexLevelParameteriv returned GL_FALSE!

Not really, it's just that when we run against a driver that advertises texture compression support but doesn't support compressing textures (eg. only a straight passthrough to the GPU), we spew this and fall back to the uncompressed path. It isn't really a big deal except for spamming your log.

What do you mean? When removing libtxc-dxtn, both GL_EXT_texture_compression_s3tc and GL_S3_s3tc extensions disappear. GL_ARB_texture_compression is still advertised, as well as GL_EXT_texture_compression_rgtc / 3dc / latc but not the S3 versions.

Also at least the

Mesa: User error: GL_INVALID_ENUM in glCompressedTexImage2D(internalFormat)

make me think that there is some misuse of OpenGL in eduke and is not simply using uncompressed textures. Or I am missing something?

[Plagman]

I think that's because you ran once with the S3TC-enabled driver, which created an S3TC-compressed disk cache, and it's now trying to re-upload it as-is into your now-DXT-less driver, so technically that's wrong. In practice we specify that you should nuke the on-disk cache when switching GPUs or drivers, so it's also expected.

[Zagro]

You are right indeed, after purging the cache I only get:

Error: glGetTexLevelParameteriv returned GL_FALSE!
