There is also same decision to make regarding libraries that have not been re-packaged to support both qt4 and qt5. One good example is https://admin.fedoraproject.org/pkgdb/package/qjson/ -> there is no separate binary package libqjson-qt5 and libqjson-qt4. The library from source works all right with both but if the library is built and linked against qt4, it can also be used to build application that links against qt5 and everything goes all right. Only downside is immediate SIGSEGV when you invoke methods from the library :) -- Antti -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
