Isn't Ubuntu likely to make the same choice that Fedora has made, at least at some point? Or is Fedora just doing this (using the C++11 libstdc++ API) because they really like C++11 and want to make the C++11 experience as good as possible? > The overarching point is that this would not depend on -std=c++11 > becoming the default, because that determines the default API, not the > ABI. > > On a different point, if gcc is to change the default API, then it seems > to me more sensible that the default should be -std=c++14. -- Murray Cumming [email protected] www.murrayc.com _______________________________________________ gtkmm-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/gtkmm-list
