Looked at things and there are 2 issues in libclc/CmakeLists.txt

  • it uses LLVM_RUNTIMES_TARGET instead of LLVM_RUNTIME_TARGETS

  • Putting more then one target in LLVM_RUNTIMES_TARGET aborts

No idea if this is intentional or a mistake.

Gentoo appears to solve this by running configure & build multiple times, see https://gitweb.gentoo.org/repo/gentoo.git/tree/llvm-core/libclc/libclc-23.0.0_pre20260413.ebuild?id=5980a3436e03b294bb69cdc52e6d069cc6f9ef47

Thanks for the alert.

Next time please link to the commit instead of posting text from it.

I can't get out of tree libclc build working with the new method. Will look at in depth when I have more time.

Confirmed, will upload a new version before monday. (no time for a full llvm/spirv build atm)

Compilation in clean chroot fails due to clang-opencl-headers-minimal-git missing in makedepends.

Lone_Wolf commented on 2024-04-13 17:21 (UTC)

The ld error was fixed upstream, but there is a new one.

https://github.com/llvm/llvm-project/pull/87622/commits/47cd6ddbf292fd8a50534e091ac64ebee3c40ee5 changes the way libclc is build and utterly breaks this package.

I am reverting that commit and have filed https://github.com/llvm/llvm-project/issues/88626 to get things hopefully solved.

No rushing intended, thanks for your work!
