Description Charalampos Stratakis 2025-02-11 05:10:22 UTC

When testing python3.14 with --enable-bolt and BuildRequires of llvm-bolt the instrumentation fails with:

BOLT-ERROR: library not found: /usr/lib/libbolt_rt_instr.a

This happens on Rawhide where Bolt is now being built from the llvm dist-git.

On Fedora 41 where Bolt is built through its own dist-git sources the issue is not present.

Reproducible: Always

Comment 1 Nikita Popov 2025-02-11 08:32:18 UTC

I believe this is due to the llvm prefix changes, not the move into the llvm dist-git.

Fails: /usr/bin/llvm-bolt a.out -instrument -o a.new.out
Works: /usr/lib64/llvm19/bin/llvm-bolt a.out -instrument -o a.new.out

Comment 2 Nikita Popov 2025-02-11 08:44:23 UTC

It looks like bolt rolled its own GetExecutablePath which does not resolve symlinks, instead of using getMainExecutable().
