[-Werror=implicit-function-declaration] gbm_device_get_format_modifier_plane_count(drmmode->gbm, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gbm_device_is_format_supported gbm_device_get_format_modifier_plane_count was only added to /usr/include/gbm.h in mesa-18. mesa-17, which I had installed for the above build, doesn't contain the function.
It was added by commit https://gitlab.freedesktop.org/mesa/mesa/commit/8824141b8d48d9120ddbf542d6fb661046c41c62 which according to git tag --contains was first in mesa-17.3.0. I believe there is a bug here, but I don't think it's due to an incorrectly versioned dependency.
Hm, the current dependency is indeed out of date: >=media-libs/mesa-10.3.4-r1[egl,gbm] Perhaps you had something older than mesa-17.3 installed?
I know it was 17.x and the function was not present in gbm.h before I updated. I'm sorry, I don't recall the exact version, but I guess it was probably before 17.3 if that's when it was added. Thanks for finding the exact commit. The point is that the 10.x is clearly wrong. The correct behaviour would have been for xorg-server to pull in the latest Mesa before attempting to build xorg-server. Instead, it tried to build using the installed version and failed.
It's in your logs. Please provide the output of > grep 'media-libs/mesa' /var/log/emerge.log | tail
(In reply to Matt Turner from comment #4) > It's in your logs. Please provide the output of > > > grep 'media-libs/mesa' /var/log/emerge.log | tail So, I shouldn't expect to hear back from you I'm guessing?
