Both currently available version of chromium in portage tree have: REQUIRED_USE="qt6? ( qt5 )" in place. Qt5 and Qt6 are afaik completely independend of each other so I don't understand why enabling qt6 also requires qt5 to be enabled. The build ends up building a shim file for each but I don't see a dependency. Looking in the src and also asking google didn't reveal any hints wether this is really necessary. Could you please check wether the REQUIRED_USE is really required? Reproducible: Always
I'll look into it, this isn't something that I've looked into since inheriting the package. A brief look at the appropriate `build.gn` suggests that qt6 still extends the qt5 build steps: https://github.com/chromium/chromium/blob/main/ui/qt/BUILD.gn#L110 If you're willing to fiddle with GN scripts and submit some changes upstream it's likely possible to tidy up the logic, but it doesn't look like Chromium currently supports what you want. If you want to test further I recommend enabling ccache and trying a few chromium builds while hacking at the ebuild.
I'm happy to help. I've also reported upstream
I'm happy to help. I've reported it upstream and have linked the issue here for reference. I have never used ccache before. Can you maybe give a short instruction how to enable it just for chromium? It's a good idea as building chromium takes over 7 hours each time.
I managed to setup ccache just for chromium. I have created to patches: one for the ebuild and one for the affected GN scripts. I'll get back to you if the build will succeed *and* chromium is usable :-)

Created attachment 887674 [details, diff] Adjust ebuild an GN files to make gtk, glib/gio and atk optional
I have attached two patches which I use since a couple of days. The first patch adds a use_qt5 to Chromiums GN files so that Qt5 and Qt6 are seperate options. The second patch came up when I studied the GN files. Chromium doesn not hard depend on GTK, it is deactivateable with use_gtk=false. The same applies to use_glib/use_gio. To disable accessiblity support, I had to make a small change so that use_atk can be supplied as build argument to gn. The ebuild changes reflect some dependencies: - enabling screencast leads to a define of WEBRTC_USE_GIO which is used as a guard fo include gio/gio.h which will not be found if use_gio=false, maybe upstream should check that in detail - support for atk/atspi requires glib - it seems that cairo, pango and gdk-pixbuf are not required for a pure Qt[5,6] build so I made that DEPEND conditional on use gtk/gtk4

Created attachment 889507 [details, diff] Adjust ebuild an GN files to make gtk, glib/gio and atk optional
I have attached updated patches which are in use for several weeks now and I haven't found any issues. I have additionally also disabled use_pangocairo if gtk is not in use. Did you have thhe chance to test yourself? It would be great if these changes could make it into the ebuild.
