Bug 938951 – app-shells/bash[pgo] fails build due to missing sys-libs/compiler-rt-sanitizers

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description fabolous.e05 2024-09-02 23:26:05 UTC]

Bash fails to build when pgo useflag is set, but compiler-rt-sanitizers in not installed, due to missing "/usr/lib/clang/18/lib/linux/libclang_rt.profile-x86_64.a".

Would you be so kind and attach the build.log and emerge --info?

same issue occurs again for ongoing llvm version bump.
I think the bash ebuild should track the used LLVM_SLOT and depend on the relative version of compiler-rt-sanitizers

This can't be done without (unnecessarily) adding llvm-r1.eclass to every single ebuild which _might_ use Clang. Ultimately, it depends on what the system is using. We can add compiler-rt-sanitizers to @system on LLVM profiles, I don't think we can do much more than that.

Well it's only relevant for pgo ebuilds, but i agree it seems overkill.
