Hey, when emerging libepoxy with "-X +egl" on a fully wayland system, it breaks pkgconfig with: /usr/bin/x86_64-pc-linux-gnu-pkg-config --shared --cflags 'gtk+-wayland-3.0 >= 3.14' Package gl was not found in the pkg-config search path. Perhaps you should add the directory containing `gl.pc' to the PKG_CONFIG_PATH environment variable Package 'gl', required by 'epoxy', not found egl.pc should be enough for gtk+, and that exists. # equery f libglvnd | grep pkgconfig /usr/lib/pkgconfig /usr/lib/pkgconfig/egl.pc /usr/lib/pkgconfig/glesv1_cm.pc /usr/lib/pkgconfig/glesv2.pc /usr/lib/pkgconfig/libglvnd.pc /usr/lib/pkgconfig/opengl.pc /usr/lib64/pkgconfig /usr/lib64/pkgconfig/egl.pc /usr/lib64/pkgconfig/glesv1_cm.pc /usr/lib64/pkgconfig/glesv2.pc /usr/lib64/pkgconfig/libglvnd.pc /usr/lib64/pkgconfig/opengl.pc [binary R ] x11-libs/gtk+-3.24.34-3:3::gentoo USE="introspection wayland -X (-aqua) -broadway -colord -cups -examples -gtk-doc -sysprof -test -vim-syntax -xinerama" ABI_X86="32 (64) (-x32)" 0 KiB [binary R ] media-libs/libepoxy-1.5.10-5::gentoo USE="egl -X -test" ABI_X86="32 (64) (-x32)" 0 KiB [binary R ] media-libs/libglvnd-1.4.0-3::gentoo USE="-X -test" ABI_X86="32 (64) (-x32)" 0 KiB (I've tried emerging with --usepkg=n but it didn't help) libglvnd[X] does install gl.pc, but it also pulls bunch of x11 libs with it, which is not desired when trying to go full wayland without x11. (I would also throw an suggestion to perhaps symlink libglvnd's egl.pc into gl.pc if "-X +egl" is specified?= Let me know what else you need. The gl/egl/glx logic for libepoxy looks wild, I guess there's something?
>libglvnd's egl.pc into gl.pc if "-X +egl" is specified?= Replacement for libGL with -X is "libOpenGL" rather than libEGL It's libGL but not linked to libGLX, and still works on Xorg making it ideal where it works (does lack a handful of features so some funky packages will fail to build with it). Ideally packages should be made to find the right library rather than "automagic" use a different one based on a gl.pc symlink, I ended up forcing it in e.g. media-gfx/imv. I guess if epoxy could consider opengl.pc instead when -X it could sort this out, not that I really checked this.
