Bug 935425 – llvm-runtimes/libcxx-19.0.0_pre20240623 ; 20.0.0_pre20240808 test fail (profile is not clang) x86_64-pc-linux-gnu/bin/ld.bfd: libc++experimental.a: error adding symbols

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Arniii 2024-07-03 18:58:21 UTC]

I guess it happens because static libraries built by gcc are not understandable by clang and vice versa.

example fail from build.log:
```
# .---command stderr------------
# | /usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld.bfd: /var/tmp/portage/sys-libs/libcxx-19.0.0_pre20240623/work/runtimes_build-abi_x86_32.x86/lib/libc++experimental.a: error adding symbols: file format not recognized
# | i686-pc-linux-gnu-clang++: error: linker command failed with exit code 1 (use -v to see invocation)
# `-----------------------------

```

also from build.log:

No need for "reproducible with ..." messages on this. I already analysed it and explained the problem. It is not something that will go away with new versions.
