Looks like an interesting and fun tool. I had to add this library: apt-get install libclam-qtmonitors-dev - I built the code but when I run I get a segfault: $ make /usr/lib/x86_64-linux-gnu/qt5/bin/uic ../mainwindow.ui -o ui_mainwindow.h /usr/lib/x86_64-linux-gnu/qt5/bin/uic ../SynthBase.ui -o ui_SynthBase.h g++ -c -m64 -pipe -O2 -Wall -W -D_REENTRANT -fPIE -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++-64 -I../../GuitarSynth -isystem /usr/include/x86_64-linux-gnu/qt5 -isystem /usr/include/x86_64-linux-gnu/qt5/QtWidgets -isystem /usr/include/x86_64-linux-gnu/qt5/QtGui -isystem /usr/include/x86_64-linux-gnu/qt5/QtCore -I. -I. -I. -o main.o ../main.cpp g++ -c -m64 -pipe -O2 -Wall -W -D_REENTRANT -fPIE -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++-64 -I../../GuitarSynth -isystem /usr/include/x86_64-linux-gnu/qt5 -isystem /usr/include/x86_64-linux-gnu/qt5/QtWidgets -isystem /usr/include/x86_64-linux-gnu/qt5/QtGui -isystem /usr/include/x86_64-linux-gnu/qt5/QtCore -I. -I. -I. -o mainwindow.o ../mainwindow.cpp In file included from /usr/include/c++/4.9/backward/strstream:51:0, from ../mainwindow.cpp:23: /usr/include/c++/4.9/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.
