Hi, A quick heads up to anybody who might run into cryptic build errors when building apps that use glibmm/gtkmm: Latest glibmm/gtkmm stack in rawhide and F23 now uses C++11 features in header files. This means when building other programs that use those headers, the C++ compiler needs to be in C++11 mode now. The fix is simple: make sure -std=c++11 is passed to the compiler. It can be done in either in upstream build scripts or hacked in downstream in spec files. I would usually always suggest to go for upstreamable fixes, but I think in this case it's fine to do it downstream as well. The reason is that the workaround is just a temporary measure until GCC switches to use C++11 by default, which is probably going to happen in F24 when GCC 6 lands. Here's an example how to do it in a spec file: http://pkgs.fedoraproject.org/cgit/inkscape.git/commit/?id=fc745c8687dd8a362235340bd3481ff18925dbaf And here's how to do it in an upstreamable way: https://git.gnome.org/browse/gnome-system-monitor/commit/?id=e5d3ac014d7acc73c5f508a937c5656ffa8f08ad or https://git.gnome.org/browse/gnome-system-monitor/commit/?id=d81fe60bc3d6a481b6bc330490fd079b5cc30acc -- Kalev -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
