No, I'm on meson (0.55.3). The snip I posted is above the snip you posted and mine is a little different in the area you posted. It looks as though you are happy with the outcome and won't be pursuing it further. However I tracked it down. For whatever reason you are not passing the tests in gst-libs/gst/gl/meson.build that leave build_gstgl = true. This causes tests/examples/meson.build to skip subdir gl. This causes the includes to be set from tests/overlay/meson.build. That file fails to mention Core in line 12. The tests/overlay/meson.build should mention Core which is in fact needed to build the overlay directory and that is a bug in that file. Your output line "Run-time dependency qt5" is coming from line 12. In my case build_gstgl is set, tests/examples/gl and tests/examples/gl/qt do the Qt checks, and I get all the headers they both need. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
