Created attachment 539632 [details] log of emerge -q1v =dev-cpp/gtkmm-3.22.2 The compiler error states: cannot convert ‘GPrivate’ {aka ‘_GPrivate’} to ‘GPrivate*’ {aka ‘_GPrivate*’} in return wayland is a globally set USE flag in this scenario.
When did you last build glibmm? I think there was a fix in there, that might not have propagated out to you due to no revbump. Though yesterday I bumped glibmm, so if you upgrade that, you should get the fix and then retry gtkmm. If you built glibmm recently, then this is something else. Please check and let us know
~leio it helped! Thanks :)
ok, marking duplicate of the glibmm bug. There's been a revbump by now, in the form of glibmm version bump *** This bug has been marked as a duplicate of bug 654776 ***
