Oh, thank you !
Maybe this variable should be documented, like for example the new
variable I_WANT_A_BROKEN_VULKAN_DRIVER is documented.
I have a GK208B chip, that I replaced with a GA102.
When I try to use the OpenCL device I get the following error on GA102:
Build Log: <built-in>:1:10: fatal error: 'opencl-c.h' file not found
this happens with both Mesa 23.2.1 and latest Mesa 24.0.0-devel from git.
The missing header in the message is found in clang-libs package on
Fedora for example, and if I add the needed -I flag to clBuildProgram(),
the error goes away. So it looks like a missing include directory inside
Clover ... ?
Unfortunately I can not add the missing -I flag to OpenCL compiler when
using clpeak or LuxMark ... without recompiling. Is there an environment
variable or some other way ?
