1. Install MinGW-W64
2. Use either *Run Terminal* from Start Menu or run *mingw-w64.bat* in the installation folder
3. Navigate to the directory with ClassiCube's source code
4. Enter `gcc -O2 -fno-math-errno *.c -o ClassiCube.exe -mwindows -lwinmm -limagehlp`
4. Enter `gcc -fno-math-errno *.c -o ClassiCube.exe -mwindows -lwinmm -limagehlp`
##### Using MinGW
I am assuming you used the installer from https://osdn.net/projects/mingw/
1. Install MinGW. You need mingw32-base-bin and msys-base-bin packages.
2. Run *msys.bat* in the *C:\MinGW\msys\1.0* folder.
2. Navigate to the directory with ClassiCube's source code
4. Enter `gcc -O2 -fno-math-errno *.c -o ClassiCube.exe -mwindows -lwinmm -limagehlp`
4. Enter `gcc -fno-math-errno *.c -o ClassiCube.exe -mwindows -lwinmm -limagehlp`

Install appropriate libs as required. For ubuntu these are: libx11-dev, libxi-dev and libgl1-mesa-dev
```gcc -O2 -fno-math-errno *.c -o ClassiCube -rdynamic -lpthread -lX11 -lXi -lGL -ldl```
```gcc -fno-math-errno *.c -o ClassiCube -rdynamic -lpthread -lX11 -lXi -lGL -ldl```

##### Raspberry Pi
Although the regular linux compiliation flags will work fine, to take full advantage of the hardware:
```gcc -O2 -fno-math-errno *.c -o ClassiCube -DCC_BUILD_RPI -rdynamic -lpthread -lX11 -lXi -lEGL -lGLESv2 -ldl```
