I rebuilt gcc with openmp and after that pixman builds successfully.
Another odd thing (maybe) is that if I rebuild gcc with -openmp then revdep-rebuild doesn't complain about pixman. So maybe it's looking for openmp but isn't really using it?
Thank you! I'll commit a fix.

Dang. That doesn't seem to be sufficient. I still get a build failure. :(
I have filed the following meson bug: https://github.com/mesonbuild/meson/issues/5115 Which I have some patches in progress for. I also have a workaround I'll submit for pixman for this.
*** Bug 681078 has been marked as a duplicate of this bug. ***
I see the upstream meson bug has been closed with a merged PR. Any chance we could backport this to the tree? Thanks
(In reply to Rémi Cardona from comment #10) > I see the upstream meson bug has been closed with a merged PR. Any chance we > could backport this to the tree? Thanks Unless you know of another instance of this problem, it'll be easier to apply a workaround to pixman.
Cheesy patch to make the build succeed (clearly NOT the right answer, but I was annoyed with the build failure, and this was a trivial way to fix it w/o a new ebuild): --- a/meson.build 2019-03-31 10:35:27.642832333 -0700 +++ b/meson.build 2019-03-31 10:35:38.958493597 -0700 @@ -376,7 +376,7 @@ config.set('PIXMAN_GNUPLOT', 1) endif -use_openmp = get_option('openmp') +use_openmp = get_option('gtk') dep_openmp = null_dep if not use_openmp.disabled() dep_openmp = dependency('openmp', required : get_option('openmp'))
