Description Maik 2019-08-15 10:55:43 UTC
media-libs/cogl has a dependency on eselect-opengl when USE="test" is set, thus blocking unmasking libglvnd usage. Stub for now to work as blocker.

Nice comment in ebuild:
# Use swrast for tests, llvmpipe is incomplete and "test_sub_texture" fails
# NOTE: recheck if this is needed after every mesa bump
Question is, when was the last recheck of this. So needs recheck and hopefully the dependency can simply be dropped.

FWIW, cogl's test suite passes for me with llvmpipe and fails with the classic swrast driver.

Patch against cogl-1.22.2.ebuild removing test useflag.

I've taken a deeper look at the ebuild and this seems quite absurd. It has dependencies to mesa[classic] and eselect-opengl when USE="test" but tests are disabled anyway with RESTRICT=test because those always fail(ed). Moreover, it uses
LIBGL_DRIVERS_PATH="${EROOT}/usr/$(get_libdir)/mesa", looks like some leftover from ancient times. At least I wouldn't know how that path could be used nowadays.
Conclusion: tests doesn't work anyway, is unmaintained, so just remove it. Attaching a patch doing so.
