Bug 924705 – mesa[X] misses libXau dependency

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description schneckus 2024-02-16 10:23:59 UTC]

media-libs/mesa[X] misses x11-libs/libXau dependency. Without this dependency the build fails regardless of other USE and USE_EXPAND flags.

[Comment 1 Matt Turner 2024-02-16 15:08:06 UTC]

I don't see any evidence that Mesa has a dependency on libXau.

Please attach a build log.

```
../mesa-23.3.5/meson.build:2009:14: ERROR: Dependency lookup for x11 with method 'pkgconfig' failed: Could not generate cflags for x11:
Package xau was not found in the pkg-config search path.
Perhaps you should add the directory containing `xau.pc'
to the PKG_CONFIG_PATH environment variable
Package 'xau', required by 'xcb', not found
```

That sounds like libxcb is missing a dep on it. But it isn't:
"""
RDEPEND="
        >=x11-libs/libXau-1.0.7-r1[${MULTILIB_USEDEP}]
        >=x11-libs/libXdmcp-1.1.1-r1[${MULTILIB_USEDEP}]
"
"""

so this sounds like the result of illegal unmerging of similar.
