@marada: makefile after step1. There i only install some dependencies.

sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev libboost-all-dev libqt5gui5 libqt5core5 libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev libminiupnpc-dev git libdb5.1-dev

however, i can help you testing the mac app if need.

Would be great to see DGC back again!
