Does anyone have an example on how to get the SDL2 to compile using WebAssembly?

There are several SDL2 Emscripten examples for compiling to ASM.js. You would follow the same process, except just direct Emscripten to generate WebAssembly using a "vanilla" LLVM's WebAssembly backend [1]. You will probably first need to compile LLVM yourself with WebAssembly experimental target enabled, as explained in the link.

There is already SDL2 support for emscripten, and emscripten can compile to WebAssembly with the WASM flag flipped on. So basically just use emcc with

-s WASM=1 -s USE_SDL=2

for WebAssembly + SDL2.

The test_sdl2* tests in emscripten's test suite have working samples in them,

A full SDL1 testcase is in the tutorial,
