yes, I just don't know what other files I need in the SOURCES argument to get the BCD display to work. It do compile and link but the display is dead. Is there a way to get genie to check for unsatisfied requirements or is this hidden by the late bindings?

Also for the record, I got a valuable tip from QMC2 regarding the lack of debugger keyboard short cuts in MAME-169 with Qt5 on Linux. Remove the appmenu-qt5 package and it works again:
Code:
sudo apt-get remove appmenu-qt5
