It would seem these two versions of mesa and glew are incompatible. Perhaps just setting both GL_SGIX_fragment_specular_lighting and GL_SGIX_fragment_lighting in glext.h might solve the problem?
Created attachment 557762 [details, diff] Patch for glew for compatibility with newer mesa Note that this also breaks compilation of media-libs/opencolorio currently. The attached patch fixes it. See here: https://github.com/nigels-com/glew/pull/198/commits/d6c2c3b9ca52af697088f280c30fe5b27f7a694f
games-rpg/eternal-lands is also affected by this bug
another breakage: can't emerge pymol because of the current incompatibility of glew and mesa anyone out there to add the patch proposed by bernd feige in comment #2 to media-libs/glew-2.1.0.ebuild ??
(In reply to hsk17 from comment #3) > anyone out there to add the patch proposed by bernd feige in comment #2 to > media-libs/glew-2.1.0.ebuild ?? There's already a PR open as you can see from the comment above yours.
