Alright I think all the int64 issues are taken care of now.
This worked well for me on Ubuntu 12.04, gcc 4.6.3, QT 4.8.1
git clone https://github.com/Tranz5/HoboNickels
cd HoboNickels
qmake HoboNickels-qt.pro
make -f Makefile
sudo ./HoboNickels-qt
Debian 6 & qt 4.6.3
This is a bit older version of QT. I will see if I can help you along. My lowest version is 4.8.1
