The compilation fails on one of the cpp files as follows

make -f makefile.jack

By changing the cast in the various error lines I was able to effect compilation.
e.g. Line 831 of mAPreferncesWindow now reads


int dac = *(( int *) audio_output->GetClientData( selected_item ));

Rather than

int dac = ( int ) audio_output->GetClientData( selected_item );


If you apply this to all the error lines and add -lpthread to the makefile.linux in the static chuck that is part of miniaudicle, then it will compile on my system at least. The above fix to a cast will work and it will not do any harm although I do not want to claim I am an expert on Cpp casting.
Monitoring iuisng qjackctl shows the jack connection going when you start the VM.

However, I can still not make any noise with this program.
