build log

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

```
FAILED: va/libva.so.2.1900.0

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
```

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

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

Comment 5 Joonas Niilola gentoo-dev 2024-05-01 07:31:56 UTC 
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
