How to compile applications made in SDL2 for Windows, from a Linux machine.

My setup: Ubuntu 20.4, gcc version 9.3.0, SDL version 2.0.10

mingw64

Install mingw64, by running the following command:

sudo apt install mingw-w64

SDL2

Clone SDL2 source:

git clone http://hg.libsdl.org/SDL
cd SDL/

Make build/ directory:

mkdir build
cd build

Configure for Windows64bit:

../configure --prefix=/tmp/sdl2-win64 --host=x86_64-w64-mingw32

or

Configure for Windows32bit:

../configure --prefix=/tmp/sdl2-win64 --host=x86_64-w64-mingw32

Make:

make
make install

Now we should get SDL2.dll and other files at /tmp/.

Build app

For 64bit Windows:

x86_64-w64-mingw32-g++ test.cpp -I/tmp/sdl2-win64/include/ -L/tmp/sdl2-win64/lib -lmingw32 -lSDL2main -lSDL2 -mwindows -o test.exe

or

For 32bit Windows:

i686-w64-mingw32-g++ test.cpp -I/tmp/sdl2-win32/include/ -L/tmp/sdl2-win32/lib -lmingw32 -lSDL2main -lSDL2 -mwindows -o test.exe

You may also need to include headers located in the folder with SDL source code you downloaded earlier: -I/some/path/SDL/include/ (This is assuming you have #include <SDL2/SDL.h> in your files)

Ship app

To ship it, you will need the executable and a few .dll files. If you run your exec it should tell what dlls does it need.

For me (and most basic Windows 64bit SDL applications) it was:

(path to git cloned SDL)/SDL/build/build/.libs/SDL2.dll
/usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/libgcc_s_seh-1.dll
/usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/libstdc++-6.dll

For 32 bit:

(path to git cloned SDL)/SDL/build/build/.libs/SDL2.dll
/usr/lib/gcc/i686-w64-mingw32/9.3-win32/libgcc_s_sjlj-1.dll
/usr/lib/gcc/i686-w64-mingw32/9.3-win32/libstdc++-6.dll (very likely)
/usr/i686-w64-mingw32/lib/libwinpthread-1.dll
