New comment by ackalker on void-packages repository https://github.com/void-linux/void-packages/issues/12760#issuecomment-507165792 Comment: The problem appears to be with how the build system installs 'megadrivers', i.e. a bunch of filenames all get symlinked to the same master file by `${wrksrc}/bin/install_megadrivers.py`. For this issue, on my system, this output from `xbps-src install` step seems relevant (full `xbps-src` install log [here](https://gist.github.com/ackalker/8377b789b50ee6e3b17ccb642e040dd1)): ``` Running custom install script '/usr/bin/python3 /builddir/mesa-19.1.1/bin/install_megadrivers.py /builddir/mesa-19.1.1/build/src/gallium/targets/vdpau/libvdpau_gallium.so.1.0.0 lib/vdpau libvdpau_r300.so.1.0.0 libvdpau_r600.so.1.0.0 libvdpau_radeonsi.so.1.0.0 libvdpau_nouveau.so.1.0.0' ``` This results in a bunch of symlinks, including `libvdpau_nouveau.so.1.0.0`, all eventually pointing to `libvdpau_gallium.so.1.0.0`.
