@luntik2012 It seems like you're building version 5.12.0 (...qtquickcontrols2-everywhere-src-5.12.0
...) but headers from 5.11.2 are included (.../usr/i686-w64-mingw32/include/qt/QtQml/5.11.2/QtQml/private/qv4qmlcontext_p.h
). That is not going to work. Please uninstall the previous version first or preferably build in a clean chroot.
This is also a known issue. Please read the pinned comment under https://aur.archlinux.org/packages/mingw-w64-qt5-base.
