Hi,
With the current master, I am able build a Qt 5 version of Mixxx using
Ubuntu Saucy
scons -j4 qt5=1
But after starting Mixxx it defaults immediately. When I try to debug it
with GDB, GDB itself defaults as well.
Has one a working QT5/Linux build? Any ideas to fix, investigate the
problem?
This is the gdb output with backtrace:
