meson-log.txt from a failed configure on a 10.7 VM is at:
In this case, clang clang-600.0.57 on 10.7 seems to be choking on "-Werror=ignored-optimization-argument”. I don’t have 10.8 or 10.9 VM’s running at the moment but would suspect that they have the same problem. Please recall that dav1d used to build OK on these systems before meson was updated to 0.56.2.
One of the devs on the dav1d project spotted that there was a recent commit to meson that appears to be the cause of this dav1d build problem:
This resulted from a commit on Oct. 4, 2020:
This stuff is all well above my pay grade but it looks to me that it would likely break our builds on older OS X versions for other ports using meson. Should we reverse this commit in our meson and file a bug upstream?
