You must be registered to see the links
Compiling on debian:
Deps:
sudo apt install qt5-qmake libonig-dev
Modify the .pro file in the top directory of the engine:
# Detect GCC
QMAKE_CXXFLAGS += -O2
QMAKE_LFLAGS += -Wl,-O1
# Detect MSVC (if needed)
win32-msvc* {
QMAKE_CXXFLAGS += /O2 /GL
}
Do the same forh the .pro file in qsp/ and gui/
qmake
make
cd build/release/bin/
LD_LIBRARY_PATH=$pwd:$PATH ./jack
