doom-for-dos-like

This is a quick but fairly complete version of the original DOOM ported to the dos-like framework. The data included is for original DOOM shareware version.

It can be built as a Windows executable or as WebAssembly to run in a browser. I have not tried running it for Linux or Mac, but the code builds at least.

You can try the web version at https://mattiasgustavsson.com/wasm/doom

Operating

While running, you can use F11 to toggle between fullscreen and windowed mode.

To start in windowed mode, add the flag -w or --window to the commandline when launching.

Building

dos-like does not make use of any complicated build systems - a simple command line call to the compiler is all that is needed to build both the Doom code and the engine itself.

Windows

From a Visual Studio Developer Command Prompt:

  cl source\doom.c source\dos.c

Mac

  clang source/doom.c source/dos.c `sdl2-config --libs --cflags` -lGLEW -framework OpenGL -lpthread

SDL2 and GLEW are required - if you don't have them installed you can do so with Homebrew by running

  brew install sdl2 glew  

Linux

  gcc source/doom.c source/dos.c `sdl2-config --libs --cflags` -lGLEW -lGL -lm -lpthread

SDL2 and GLEW are required - if you don't have them installed you can do so on Ubuntu (or wherever apt-get is available) by running

  sudo apt-get install libsdl2-dev
  sudo apt-get install libglew-dev

WebAssembly

  wasm\node wasm\wajicup.js -embed doom1.wad doom1.wad -template template.html source\doom.c source\dos.c doom.html

A WebAssembly build environment is required. You can download it (for Windows) here: github.com/mattiasgustavsson/dos-like/releases/tag/wasm-env. Unzip it so that the wasm folder in the zip file is at your repository root.

The wasm build environment is a compact distribution of node, clang/wasm-ld, WAjic and wasm system libraries.
