Compiling DOS Wasm X from Source

You will need a Linux environment to build DOS Wasm X

• create a folder outside of this repo to install emscripten
• git clone https://github.com/emscripten-core/emsdk.git
• cd emsdk
• ./emsdk install 3.1.49
• ./emsdk activate 3.1.49
• source ./emsdk_env.sh
• replace Binaryen with special version
  • replace the file wasm-opt in emsdk/upstream/bin/wasm-opt with the one from this repo code/wasm-opt
  • navigate to the emsdk/upstream/bin/ folder and run chmod +x wasm-opt
  • this is needed because default Binaryen does not support Exceptions and Asyncify together
  • huge credit goes to @Caiiiycuk for developing this!
  • see references below if you prefer to get wasm-opt directly from his releases page
• navigate back to the code folder in the DosWasmX repo
• run make
  • you will get a build error towards the end saying EM_CACHE_IS_LOCKED
  • to get past this error simply copy the faulting emcc command from the terminal and run it manually (See screenshot below)
  • this should succeed and then run make again to finish building
  • later builds should not get this error after you do this one time fix
• this process will update the main.js and main.wasm files in your dist folder
• now serve the dist folder from a webserver and Enjoy!
