Description Georgy Yakovlev archtester gentoo-dev 2020-10-02 17:42:19 UTC
fails a lot of tests.

looks like we need to --force-target=generic-gnu on ppc64be (but not le) as well.

I have this diff in mind, currently testing

Comment 1 Georgy Yakovlev archtester gentoo-dev 2020-10-02 18:06:07 UTC
disregard the patch, build system already assumes generic-gnu target itself on powerpc64-*-gnu CHOST.

    media-libs/libvpx: add 1.11.0
    Notably now forcing specific targets only where we
    know libvpx works well and otherwise using
    the generic implementation due to
    runtime breakage (and extensive test failures).

We've applied a bunch of workarounds like this in 1.11.0. obviously feel free to reopen if any issues remain
