Bug 605576 – app-eselect/eselect-opencl-1.1.0-r4: Fails to set cl_egl.h when switching to Mesa

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Jonathan Scruggs (RETIRED) 2017-01-13 13:52:37 UTC]

I had opencl set to ocl-icd, and then installed Mesa. I used the command:
# eselect opencl set 1 (which is mesa on my system)

However, when I list the files, cl_egl.h is still set to the old ocl-icd header file:

# ls -l /usr/include/CL
total 0
lrwxrwxrwx 1 root root 49 Jan 13 13:28 cl_egl.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl_egl.h
lrwxrwxrwx 1 root root 51 Jan 13 13:39 cl_ext.h -> ../../lib64/OpenCL/vendors/mesa/include/CL/cl_ext.h
lrwxrwxrwx 1 root root 54 Jan 13 13:39 cl_gl_ext.h -> ../../lib64/OpenCL/vendors/mesa/include/CL/cl_gl_ext.h
lrwxrwxrwx 1 root root 50 Jan 13 13:39 cl_gl.h -> ../../lib64/OpenCL/vendors/mesa/include/CL/cl_gl.h
lrwxrwxrwx 1 root root 47 Jan 13 13:39 cl.h -> ../../lib64/OpenCL/vendors/mesa/include/CL/cl.h
lrwxrwxrwx 1 root root 49 Jan 13 13:39 cl.hpp -> ../../lib64/OpenCL/vendors/mesa/include/CL/cl.hpp
lrwxrwxrwx 1 root root 56 Jan 13 13:39 cl_platform.h -> ../../lib64/OpenCL/vendors/mesa/include/CL/cl_platform.h
lrwxrwxrwx 1 root root 51 Jan 13 13:39 opencl.h -> ../../lib64/OpenCL/vendors/mesa/include/CL/opencl.h

All the others are set to the mesa directory. The Mesa file does exist:

# find / -name cl_egl.h
/home/jon/ebuilds/b/3rdparty/include/opencl/1.2/CL/cl_egl.h
/home/jon/ebuilds/a/3rdparty/include/opencl/1.2/CL/cl_egl.h
/usr/lib64/OpenCL/global/include/CL-1.2/cl_egl.h
/usr/lib64/OpenCL/global/include/CL-2.1/cl_egl.h
/usr/lib64/OpenCL/global/include/CL-2.0/cl_egl.h
/usr/lib64/OpenCL/vendors/mesa/include/CL/cl_egl.h
/usr/include/CL/cl_egl.h

Thus it should be used instead.

Cheers.

This is even more broken in the latest version of Mesa.
