Description Linus Lotz 2022-09-24 18:34:30 UTC

The rust based opencl implementation rusticl was merged in mesa a while ago, but it is not possible to build mesa with rusticl, as there is no use flag for it.

Reproducible: Always




The documentation for building mesa with rusticl: https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/docs/rusticl.rst

mesa-9999.ebuild with rusticl IUSE, RDEPEND and emesonargs

According to https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/docs/rusticl.rst, rustfmt is only needed for CI and debug, but bindgen is pulling it in, and the link says bindgen is required. 


Required Useflags:

dev-lang/rust rustfmt                                                                          
virtual/rust rustfmt                                                                           
media-libs/mesa rusticl

Weird, PKG_CONFIG_LIBDIR needs to point to /usr/lib/llvm/15/lib64/pkgconfig or LLVMSPIRVLib won't be found: https://github.com/gentoo/gentoo/pull/28209/files#diff-6c473421061cb7b3f14120cd9f34d9e88cb35c258b00e1c776909a25eab0840fR404

Does it work for you without it?

    media-libs/mesa: use rusticl instead of clover
    
    This has two notable regressions:
      - No multilib support
      - No R600 support
