Building on Linux:

These instructions are for Debian-based distros and were tested with Ubuntu 24.04 LTS. For others it should be similar.

Note: this is experimental. None of the developers are using Linux as a desktop OS, so you're pretty much on your own if you encounter any problems with running the application.

  • Install Mono. The mono-complete package from the Debian repo doesn't include msbuild, so you have to install mono-complete by following the instructions on the Mono project's website: https://www.mono-project.com/download/stable/#download-lin
  • Install additional required packages: sudo apt install make g++ git libx11-dev libxfixes-dev mesa-common-dev
  • Go to a directory of your choice and clone the repository (it'll automatically create an UltimateDoomBuilder directory in the current directory): git clone https://github.com/jewalky/UltimateDoomBuilder.git
  • Compile UDB: cd UltimateDoomBuilder && make
  • Run UDB: cd Build && ./builder
