Justin Hibbits <jhibbits at FreeBSD.org> has reassigned Bugzilla Automation
<bugzilla at FreeBSD.org>'s request for maintainer-feedback to gnome at FreeBSD.org:
Bug 222014: x11-toolkits/gtkmm30 fails to build with gcc5
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222014



--- Description ---
x11-toolkits/gtkmm30 uses the function std::stod(), which is not available on
FreeBSD in gcc5 (guarded by c++11 and _GLIBCXX_USE_C99).  This has changed for
gcc6.
