Using source files at https://svn.code.sf.net/p/qmc2/code/trunk.
In order to build in Ubuntu 17.10 the config file needs to be as follows (Ubuntu_17.10.cfg or Debian.cfg),
QMAKE = /usr/bin/qmake
LUPDATE = /usr/bin/lupdate
LRELEASE = /usr/bin/lrelease
This will allow QMC2 Arcade to build and install.
QMC2 (non arcade version) does not build with the latest version of QT5.
Good to see you back, Rene.
