LinuxDoom+ is a source port based on LinuxDoom v1.10, it is aimed at vanilla compatibility while adding new features

Fork of idSoftware/DOOM (linuxdoom-1.10), uses modified code from SDLDoom to work on SDL2.

You need to have sdl2, sdl2_mixer, and sdl2_net, you can install these in whatever Linux distro you have, if you are using Windows, there soon will be instructions on setting up a compiling environment,

Example: on Arch Linux

sudo pacman -S sdl2 sdl2_mixer sdl2_net

Then, clone the repository, and type

make

The output will be in the linux/ folder
