I have a component that uses QToolButton. When I build it in my run script, the build works well.
When I want to build my src package I get the following error message:
button.o:(.data.rel.ro._ZTIN14Launcher_slice6ButtonE[_ZTIN14Launcher_slice6ButtonE]+0x10): undefined reference to `typeinfo for QToolButton'
I have an other component that uses QPushButton where I can build the src archive. If I replace QPusButton with QToolButton in this component, I get the same error.
The following command reveals the reason of this error: a missing entry for the QToolButton typeinfo symbols in https://github.com/cproc/genode-symbols.
c++filt < $(./tool/ports/current qt5)/lib/symbols/qt5_widgets | grep 'typeinfo.*Q[A-z]*Button'
So please add the missing symbol to the qt5_widgets file above and rebuild your depot. It would be nice if you'd report your fixes in the issue tracker.
BTW I doubt that your note about those errors comming and going without any changes is correct, Ben. Maybe you just missed an update of the abovementioned repository.
