    Ubuntu 18.04 LTS 64 bit
 clang 6.0
I configured current dev branch with
-platform linux-clang -static -developer-build -opensource -confirm-license -nomake examples -nomake tests
Running make then ends with lots of errors like:
/usr/bin/ld.gold: error: /home/qtrob/dev/clang-6.0.0/qt-dev-static/qtbase/plugins/wayland-shell-integration/libxdg-shell.a(qwayland-xdg-shell.o): multiple definition of 'QtWayland::xdg_surface::ack_configure(unsigned int)' /usr/bin/ld.gold: /home/qtrob/dev/clang-6.0.0/qt-dev-static/qtbase/plugins/wayland-shell-integration/libxdg-shell-v5.a(qwayland-xdg-shell-unstable-v5.o): previous definition here
