This was reported by someone else with 6.6.0, but that bug was closed: https://bugs.gentoo.org/show_bug.cgi?id=915953 I've not tried to rebuild yet, but from reading that it smells like a race condition.

Created attachment 881792 [details] /var/tmp/portage/dev-qt/qtwebengine-6.6.1/temp/build.log xzcat it
I've seen like 3 or 4 users run into this so far (somewhat rare), does sound like a race condition but no idea. This header seems to be handled the same as the rest and ultimately should be found at: /var/tmp/portage/dev-qt/qtwebengine-6.6.1/work/qtwebengine-everywhere-src-6.6.1_build/include/QtWebEngineCore/6.6.1/QtWebEngineCore/private/qtwebenginecoreglobal_p.h (it's a placeholder to find the header even if not installed, it #include the real header) I did see one user claim they hit the error with MAKEOPTS=-j1 which could indicate something else happened, but I never seen the full build.log to confirm that. It eventually worked again when they tried again and moved on. Back in bug #915953 that you noted I thought pdfium was suspicious but other cases (here included) were not enabling it, so can rule that out. Never been able to reproduce myself so far.
There's been similar sounding bugs upstream, but didn't really go anywhere -- e.g. for a few: https://bugreports.qt.io/browse/QTBUG-101023 https://bugreports.qt.io/browse/QTBUG-107169 (duplicate of an unrelated sounding bug?) https://bugreports.qt.io/browse/QTBUG-94343 (this one apparently didn't pass the -I but should be fixed?)
Anyhow, do suspect it will work if try again. May want to changeup the -jX value to reduce odds of hitting the same pattern. Fixes welcome or asking upstream if anyone want to pursue this further.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2e0505f87184b97e3eeb1621171beda057b5ba9c commit 2e0505f87184b97e3eeb1621171beda057b5ba9c Author: Ionen Wolkens <ionen@gentoo.org> AuthorDate: 2024-01-10 08:35:38 +0000 Commit: Ionen Wolkens <ionen@gentoo.org> CommitDate: 2024-01-10 09:08:21 +0000 dev-qt/qtwebengine: tentatively work around race condition (qt6) Unknown if this really helps, depend on if the file was missing or if it was just failing to find where it is with bad include search -- but given it is generated good odds it is the former. Have not actually reproduced myself and it is possible another target also needs to be run, could potentially fail differently if that does not resolve it (forcing -j1 is of course out of the question for this package). Needs a proper investigation/fix, but given this tend to fail very late in the build it is not obvious and ccache likely makes it harder to fail. Does not help that these rules are created through several Qt cmake wrapper functions (the sync headers bits come from qtbase cmake files, not from here). May tentatively try to remove in a somewhat-distant future to see if it is still an issue, and/or when related-sounding fixes occurred in qtbase or qtwebengine.
