mpv fails to compile with the ebuild for 0.38/0.39:

Detecting compiler via: `x86_64-pc-linux-gnu-gcc --version` -> 0
stdout:
x86_64-pc-linux-gnu-gcc (Gentoo Hardened 12.4.0 p1) 12.4.0 |
Fetching the mpv source code from Github and compiling via:
meson setup build && meson compile -C build && DESTDIR=/tmp/test meson install -C build
works fine. |

I'd say compare with the results of the -rdynamic test in the meson-log.txt file from your manual build.
The linker currently selected by your eselect binutils is ignoring the -Wl,-z,pack-relative-relocs option from the 23.0 amd64 profile for the build requested by this test, and telling you. I don't know if this is supposed to happen or not, but it is only a warning. The problem is, a -Wl,--fatal-warnings option is also passed somehow; I don't know where this is coming from —certainly not the profile; maybe it's the build system, maybe not—, but turns the warning into a fatal error, so the Meson test fails.

| Old binutils is likely selected. |

| Using meson directly will work regardless because (by default) it'll disable cplugins support if the test failed while the ebuild expect that test to actually pass and force enables it to be sure. |
