Created attachment 193512 [details] qt5-qmake porting failure Seems like it needs porting patch from `g++` calling to `c++` or direct `g++6` for e.g. Work arounded for now via `ln -s /usr/local/bin/g++6 /usr/local/bin/g++` ports tree , kernel & world latest. Thank you for development.
Are you using portmaster? There was a problem with it that has been fixed in ports r470312.
(In reply to Tijl Coosemans from comment #1) Yes, v. 3.19_9 Updated to v. 3.19_10 - will see later.
See, e.g. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204923 and https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=208811 . Qt's tools are defined by the mkspecs, not by environment variables.
