Created attachment 742548 [details] Build log of libomp-13.0.0 Latest updates on ~amd64 and compilation of 'sys-libs/libomp-13.0.0' fails during configure.

These libraries are part of sys-devel/llvm but they are not exported. That is why cmake is unable to find them. Hacking the llvm ebuild like this allows libomp to compile : --- /mnt/repos/gentoo/sys-devel/llvm/llvm-13.0.0.ebuild 2021-10-01 18:54:19.110648000 -0400 +++ /mnt/repos/fixes/sys-devel/llvm/llvm-13.0.0.ebuild 2021-10-03 15:32:20.936414000 -0400 @@ -204,6 +204,18 @@ LLVMDemangle LLVMSupport LLVMTableGen + + # libraries needed for libomp + LLVMBinaryFormat + LLVMBitReader + LLVMBitstreamReader + LLVMCore + LLVMDebugInfoCodeView + LLVMMC + LLVMMCParser + LLVMObject + LLVMRemarks + LLVMTextAPI ) if multilib_is_native_abi; then
Does it really build for you though? I'm getting a ton of errors such as: /tmp/portage/sys-libs/libomp-13.0.0/work/openmp/libomptarget/plugins/amdgpu/src/rtl.cpp:505:18: error: ‘AMDGPUGpuGridValues’ is not a member of ‘llvm::omp’; did you mean ‘AMDGPUGridValues64’? 505 | llvm::omp::AMDGPUGpuGridValues[llvm::omp::GVIDX::GV_Max_Teams]; | ^~~~~~~~~~~~~~~~~~~ | AMDGPUGridValues64 My totally random guess is that this release is seriously screwed up.

Nevermind, the ebuild needs adjusting to use LLVM 13.
