[EPEL-devel] OpenColorIO: Build failing but package hasn't changed

[Richard Shaw]

I fixed a build problem for OpenColorIO for EPEL 7 a few weeks ago and was
able to do mockbuilds. I just forced a Koschei rebuild to clear the failure
but the build failed[1] for an unusual reason:

In file included from
/builddir/build/BUILD/OpenColorIO-1.0.9/src/apps/ociodisplay/main.cpp:46:0:
/usr/include/GL/glext.h:12066:105: error: conflicting declaration 'typedef
void (* PFNGLFRAGMENTLIGHTFVSGIXPROC)(GLenum, GLenum, const GLfloat*)'
 typedef void (APIENTRYP PFNGLFRAGMENTLIGHTFVSGIXPROC) (GLenum light,
GLenum pname, const GLfloat *params);

                             ^

 typedef void (GLAPIENTRY * PFNGLFRAGMENTLIGHTFVSGIXPROC) (GLenum light,
GLenum pname, GLfloat* params);

The mesa-libGL-devel package has changed versions (glext.h) since the last
successful build[2] but the glew-devel package has not (glew.h) and yet it
also is causing an issue somehow.

Any pointers?

Thanks,
Richard
