title="RESOLVED NOTOURBUG - Second Life shaders fail to compile (extension declared in middle of shader)"
href="show_bug.cgi?id=71591">bug 71591</a> about allowing (some) extension declarations in
middle of shader. After that is allowed (there are Mesa patches for that),
both Unigine tests run [1].
However, Valley benchmark is still lacking most of lightning. That can be
worked around by running it with:
MESA_EXTENSION_OVERRIDE="-GL_ARB_blend_func_extended"
MESA_GL_VERSION_OVERRIDE=3.2 ./valley
If one specifies some other Mesa version, there are GL enum errors and
lightning doesn't work. Without blend override, there aren't error messages,
but lightning doesn't work either, regardless of specif Mesa. I.e. there might
be some bug in Mesa GL_ARB_blend_func_extended implementation.
[1] If you don't patch Mesa to allow extension declarations in middle of
shaders, you need to add "-GL_ARB_sample_shading" to MESA_EXTENSION_OVERRIDE.</pre>
