For a reason FreeBSD doesn’t support Qt5 build tools out of box. There are a few problems that have to be solved before you can run qmake && make to build a project. Firstly, my default setup didn’t have QMAKESPEC specified, add this line to your .bashrc/.zshrc:
export QMAKESPEC=freebsd-g++ |
Also add this line to specify Qt5 theme:
export QT_QPA_PLATFORMTHEME=qt5ct |
