I had some trouble compiling the Linux QT version.
I was getting odd errors in the file "statisticspage.cpp". But after some research, I believe that I solved the problem.
Just change line 95 in statisticspage.cpp:
from this
QString qVolume = QLocale(QLocale::English).toString(volume);
to this
QString qVolume = QLocale(QLocale::English).toString(int(volume));
and compile with QT5.
