In a clang-17[default-libcxx] environment, media-libs/libva-2.19.0 will fail to link during emerge with the following error message:

```

clang: error: linker command failed with exit code 1 (use -v to see invocation)

```

This can be avoided by passing "-Wl,--undefined-version" to LDFLAGS.

Attaching logs.

https://github.com/intel/libva/pull/758

Just released libva-2.20.0 will possibly fail the same.

[Comment 3 Brahmajit Das 2023-10-11 08:35:46 UTC]

Reproducible with media-libs/libva-2.20.0

Still getting this with media-libs/libva-2.21.0

The patch https://patch-diff.githubusercontent.com/raw/intel/libva/pull/758.patch from https://github.com/intel/libva/pull/758 fixes compilation at least.

[Comment 6 Amit Ugol 2024-05-05 05:55:45 UTC]

can confirm that the patch 'fixed' compilation for media-libs/libva-2.21.0 on clang version 18.1.4+libcxx
