-X, +X, doesn't matter. libdrm installed or not, doesn't matter. Fails same way. Oh and just to be sure it's not binpkg-related, I've done emerge -e qtwayland --usepkg=n, which didn't help.
If I emerge it using plasma profile, it works. Could there be some automagic on libdrm?
After comparing installed packages when using profiles default/linux/amd64/17.1 default/linux/amd64/17.1/desktop/plasma and trying out few combinations, it seems to boil down to this: qtwayland needs dev-qt/qtgui[jpeg] in addition to its current list. This fixes emerging qtwayland with -X +X. I can commit without revbumping if you ack.

Reverting this was the right thing to do. - dev-qt/ is not up for random commits - RDEPEND changes require revbumps
(In reply to Andreas Sturmlechner from comment #11) > Reverting this was the right thing to do. > > - dev-qt/ is not up for random commits I saw you were active during the time between comments 6-7, so I thought you had seen them. But yeah I'll wait for a clear ack next time. > - RDEPEND changes require revbumps It seems this pretty much only appears on tinderboxes, and the build error is rather clear. So I made a judgement call to not revbump (and seeing it got reverted, I'm somewhat glad about that!) I'm still going to get to this since it looks like I've discovered something. I've googled a bit and found some patches that I'm gonna try, too. But I'll make a PR and wait for an ack next time and try to _really_ understand why this is happening.
(In reply to Joonas Niilola from comment #12) > I saw you were active during the time between comments 6-7, ... Don't go that route. 1) If you want to make substantial changes to Qt ebuilds, file a PR and assign pesa 2) I won't react to outlandish theories while on holidays, which I actually was during that time, so don't take an arbitrary measurement of 'activity' as an excuse to skip due diligence.
Here's how I can reproduce and fix the issue every time it seems: # emerge -1av qtwayland --usepkg-exclude dev-qt/qtgui --usepkg-exclude dev-qt/qtwayland -> >>> Failed to emerge dev-qt/qtwayland-5.15.5-r1 Project ERROR: Test config.qtwayland_client.tests.dmabuf-server-buffer tries to use undeclared library 'drm' * ERROR: dev-qt/qtwayland-5.15.5-r1::gentoo failed (configure phase): # emerge -1av mesa # emerge -1av qtwayland --usepkg-exclude dev-qt/qtgui --usepkg-exclude dev-qt/qtwayland -> >>> Failed to emerge dev-qt/qtwayland-5.15.5-r1 Project ERROR: Test config.qtwayland_client.tests.dmabuf-server-buffer tries to use undeclared library 'drm' * ERROR: dev-qt/qtwayland-5.15.5-r1::gentoo failed (configure phase): # emerge -1av qtgui qtwayland --usepkg-exclude dev-qt/qtgui --usepkg-exclude dev-qt/qtwayland -> >>> Installing (1 of 2) dev-qt/qtgui-5.15.5-r2::gentoo -> >>> Installing (2 of 2) dev-qt/qtwayland-5.15.5-r1::gentoo So my conclusion: when compiling qtgui with mesa around it does some magic that later makes qtwayland successful. There's no difference in vdb's NEEDED file unfortunately. Sorry nothing concrete but a step ahead?
Saw this issue in the wild from some setting up a new install. Rebuilding dev-qt/qtgui worked as the workaround, but its not media-liba/mesa + dev-qt/qtgui automagic that is exactly the issue. dev-qt/qtgui does several test in which it includes x11-libs/libdrm in the results of these tests which are saved in a private header. So if drm isnt present when qtgui is merged then values like QMAKE_LIBS_DRM are unset. The issue arises from qtwayland relying on qtguis private headers for these values. So I tested this in chroot and got like four results. x11-libs/libdrm unmerged and dev-qt/qtgui built when x11-libs/libdrm was unmerged leads to the issue. * x11-libs/libdrm unmerged and dev-qt/qtgui built when x11-libs/libdrm was merged succeeds. * x11-libs/libdrm merged and dev-qt/qtgui built when x11-libs/libdrm was unmerged leads to the issue. * x11-libs/libdrm merged and dev-qt/qtgui built when x11-libs/libdrm was merged succceeds. So take aways are that x11-libs/libdrm being merged does not affect dev-qt/qtwayland BUT x11-libs/libdrm being merged or unmerged when dev-qt/qtgui was built does affect dev-qt/qtwayland. So I dont think touching or revdumping dev-qt/qtgui makes sense. dev-qt/qtwayland src/compositor/configure.json needs to be patched for the optimal user experience so that unlucky merge order doesnt lead to issues. Ill have a look at that, but posting this first.
Created attachment 859272 [details, diff] Patch: Do not rely on qtgui private header for libdrm and egl Looking further I notice that this may be also affected by a kde patch applied which partly undoes https://github.com/qt/qtwayland/commit/1344ca6b5a8fbc1b28727feea6d856af8bf3bc93 https://invent.kde.org/qt/qt/qtwayland/-/commit/20af00d0fb9da337d16b6d464ade52de39d39bf0 The bugs mentioned in the commits. https://bugreports.qt.io/browse/QTBUG-83303 https://bugreports.qt.io/browse/QTBUG-100475 This patch should address both of the above by adding checks drm and egl (unlike drm, egl atleast didnt cause a configure error). I did not take static libs into account so they may be adversely affected, but I dont think they matter for Gentoo.
Wow, that's thorough. Thanks for your efforts! I suspect this is a tinderbox-only bug to begin with, but patching it (upstream) obviously doesn't hurt.
ci has reproduced this issue with version 5.15.10-r4 - Updating summary.
Just FYI, this bug is also reproduced when using a custom profile combining standard plasma and no-multilib profiles
