Re: /usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/libQxtWidgets-qt5.so: undefined reference to `vtable for QxtApplication'

At a guess, and not having looked at the code or logs, I would say it’s either a virtual destructor defined in a header file (that can cause problems with the vtable not being generated by any compilation unit) or it has been built with -fvisibility=hidden and the class is not marked with visibility(“default”) and so members are not exported from the library> Michael On Tue, 28 Nov 2017, at 09:17 PM, Martin Gansser wrote: > Maybe someone can tell me which forum I can contact to fix this > error?> > _______________________________________________ > devel mailing list -- devel(a)lists.fedoraproject.org > To unsubscribe send an email to devel-leave(a)lists.fedoraproject.org>
