Description Vinson Lee 2014-05-19 07:56:19 UTC

mesa: 9e74de884a0595e577ebdfb7c7c13f4fd4d4dff5 (master 10.3.0-devel)

configure error on Fedora 21. stddef.h is located at /usr/lib/clang/3.4/include/stddef.h.

$ ./autogen.sh --enable-opencl
[...]
checking for llvm-config... /usr/bin/llvm-config
configure: error: Could not find clang internal header stddef.h in /usr/lib64/llvm/clang/3.4 Use --with-clang-libdir to specify the correct path to the clang libraries.

Mesa looks for the standard installation path.
It seems that Fedora install the header in another one. As sugested by the error message you should use --with-clang-libdir=/usr/lib64/llvm/clang/3.4
