libQGLViewer (http://www.libqglviewer.com/) is a library that can be build with either Qt4 or Qt5, with recent versions. I am considering providing packages build with both Qt4 and Qt5. I personally need both versions for my daily job (to test compatibility). I do not think we already have such libraries in Fedora. Do we have relevant packaging guidelines for such a case? https://admin.fedoraproject.org/pkgdb/acls/name/libQGLViewer -- Laurent Rineau http://fedoraproject.org/wiki/LaurentRineau -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
