### Cross compile apple2sdl.exe for Windows in Ubuntu
Install the mingw cross compile tools and the [SDL2 Windows libs for mingw](https://www.libsdl.org/download-2.0.php).
```
$ sudo apt install mingw-w64
$ wget https://www.libsdl.org/release/SDL2-devel-2.0.9-mingw.tar.gz
$ tar -xzf SDL2-devel-2.0.9-mingw.tar.gz
$ sudo cp -r SDL2-2.0.9/x86_64-w64-mingw32/* /usr/x86_64-w64-mingw32
```
Compile:
```
$ env CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc GOOS=windows CGO_LDFLAGS="-L/usr/x86_64-w64-mingw32/lib -lSDL2 --verbose" CGO_FLAGS="-I/usr/x86_64-w64-mingw32/include -D_REENTRANT" go build -o apple2sdl.exe -x *.go
```
To run the executable in Windows, copy the file `SDL2.dll` on the same folder. The latest `SDL2.dll` can be found in the [Runtime binary for Windows 64-bit](https://www.libsdl.org/download-2.0.php)
