Hi :-) I'm just about to update an old x86 notebook running LxQt. The process is stuck at dev-qt/qtwayland, which refuses to even start building: ------------------------------------------------------------ Running configuration tests... Checking for Wayland client library... no Checking for Wayland EGL library... no Checking for wayland-server... no Done running configuration tests. Configure summary: Qt Wayland Client ........................ no Qt Wayland Compositor .................... no Note: No wayland-egl support detected. Cross-toolkit compatibility disabled. ERROR: Feature 'xcomposite-egl' was enabled, but the pre-condition 'features.wayland-client && features.opengl && features.egl && features.xlib && libs.xcomposite && features.egl_x11' failed. ERROR: Feature 'xcomposite-glx' was enabled, but the pre-condition 'features.wayland-client && features.opengl && !features.opengles2 && features.xlib && libs.xcomposite && libs.glx' failed. ERROR: Feature 'xcomposite-egl' was enabled, but the pre-condition 'features.wayland-server && features.egl && features.opengl && libs.xcomposite' failed. ERROR: Feature 'xcomposite-glx' was enabled, but the pre-condition 'features.wayland-server && features.opengl && !features.opengles2 && libs.xcomposite && libs.glx' failed. ------------------------------------------------------------ I didn't change any USE flag and also have none set globally. I can't figure out how to fix this ... what's missing? Apparently, I need qtwayland, as lxqt-base/lxqt-config depends on kde-plasma/libkscreen, which depends on kde-frameworks/kwayland, which then pulls dev-qt/qtwayland.
Setting USE="-X" for dev-qt/qtwayland makes this one build, but afterwards, kde-frameworks/kwayland fails to configure: CMake Error at /usr/lib/cmake/Qt5/Qt5Config.cmake:28 (find_package): Could not find a package configuration file provided by "Qt5WaylandClient" with any of the following names: Qt5WaylandClientConfig.cmake qt5waylandclient-config.cmake Add the installation prefix of "Qt5WaylandClient" to CMAKE_PREFIX_PATH or set "Qt5WaylandClient_DIR" to a directory containing one of the above files. If "Qt5WaylandClient" provides a separate development package or SDK, be sure it has been installed.

So the tests fail right at the start, where they're looking for things provided by 'dev-libs/wayland' I believe. Is that properly installed and which version do you have of it? Can't quite imagine it being missing. Maybe something going wrong with pkgconfig. The files 'config.cache' and 'config.log' might be interesting, though they might not tell us many things we already don't know. So far I've been unable to re-produce this in a VM, but that might not be much said...
Do you still have eselect-opengl on that system?
Looking at config.log was a really good idea. Apparently, distcc is the problem: > g++ -Wl,-O1 -o wayland-server main.o -lwayland-server > /usr/lib/gcc/i686-pc-linux-gnu/9.3.0/../../../../i686-pc-linux-gnu/bin/ld: i386:x86-64 architecture of input file `main.o' is incompatible with i386 output > collect2: Fehler: ld gab 1 als Ende-Status zurück > distcc[202] ERROR: compile (null) on localhost failed > make: *** [Makefile:68: wayland-server] Fehler 1 => source failed verification. test config.qtwayland_compositor.libraries.wayland-server FAILED I fixed all /usr/lib/distcc/* links to use the wrapper script and that made it compile. Apparently, some were lost due to an update ... Thanks for pointing me into the right direction, I honestly didn't think about distcc being the problem here!
Aha! Interesting. I don't remember ever seeing distcc causing trouble during configure tests like this before... but I admit I didn't even notice it was enabled there. Always learning new, and all that. Thanks! Not sure if this is a distcc or qtwayland bug now, hmmm...
I think the problem was that the configure script used the distcc g++ executable that was symlinked to distcc directly. The host is x86, and the distcc machine is amd64. Without the wrapper script changing this to i686-pc-linux-gnu-g++, the server delivered an amd64 binary (not knowing the host wanted i686) and thus the linking failed on the x86 machine. So most probably, this is neither a distcc, nor a qtwayland issue, but a Gentoo-specific one which only emerges in a cross-platform distcc environment, when i686 mixes with amd64 and the distcc wrapper is not setup correctly ...
Seems plausible, and with that, I guess this one can be closed (invalid in the sense that there doesn't seem to be a packaging issue here). Thanks!
