Adam Ford reported at [1] that xwayland randomly fails to build with a
missing dri dependency.
I had run into the same error on xorg-server earlier and didn't have a
solid solution for it at the time.
Fix the issue in both packages.

However, this cannot be correct as mesa3d is not the only OpenGL provider. BR2_PACKAGE_HAS_LIBGL only tells you "some OpenGL provider is available" and that "libgl" depends on this OpenGL provider. But there are plenty of OpenGL providers which are not mesa3d. What is the failure that you are seeing, with which configuration?

LIBGL specifically is only provided by 3 packages, mesa3d, libglvnd and nvidia-driver. LIBGLES on the other hand. However, that doesn't matter anymore, due to below. > > What is the failure that you are seeing, with which configuration? I realize I stupidly forgot to include the error in the commit message: configure: error: Package requirements (fixesproto >= 6.0 damageproto >= 1.1 xcmiscproto >= 1.2.0 xtrans >= 1.3.5 bigreqsproto >= 1.1.0 xproto >= 7.0.31 randrproto >= 1.6.0 renderproto >= 0.11 xextproto >= 7.2.99.901 inputproto >= 2.3.99.1 kbproto >= 1.0.3 fontsproto >= 2.1.3 pixman-1 >= 0.27.2 videoproto recordproto >= 1.13.99.1 resourceproto >= 1.2.0 xf86driproto >= 2.1.0 glproto >= 1.4.17 dri >= 7.8.0 dri3proto presentproto >= 1.2 xineramaproto xkbfile pixman-1 >= 0.27.2 xfont2 >= 2.0.0 xau xshmfence >= 1.1 xdmcp) were not met: Package 'dri' not found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Adding these configurations to the x86_64_efi_defconfig: +BR2_PER_PACKAGE_DIRECTORIES=y +BR2_PACKAGE_LIBGLVND=y +BR2_PACKAGE_MESA3D=y +BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_NOUVEAU=y +BR2_PACKAGE_MESA3D_OPENGL_GLX=y +BR2_PACKAGE_XORG7=y +BR2_PACKAGE_XSERVER_XORG_SERVER=y And it took me a while to realize it's this exact config, because I overlooked how the libgl dependency actually worked since this was the first configuration I tried. LIBGLVND selected is the key. I had it de-selected testing something else in between, and couldn't for the life of me reproduce the issue and thought I had ghosts in my machine.. So this patch set is all wrong, and something is not quite right with mesa3d (the only DISPATCH_GL provider) or libglvnd. Should there be a virtual package for gl-provider perhaps to complete the dependency chain?
