To compile and install FCEUX for SDL, follow the instructions in the README-SDL.md file. Users of Microsoft Visual Studio can use the solution files within the vc directory. These solution files will compile FCEUX and some included libraries for full functionality. The SDL port build tool of choice has come full circle back to Cmake. The cmake build tool will compile the new Qt version of the SDL GUI. The scons build tool will build the older GTK based GUI which currently only builds on Linux.
