Building on Linux

These instructions are for Debian-based distros and were tested with Ubuntu 24.04 LTS and Arch.

Note: this is experimental. None of the main 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
  • Ubuntu: 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
  • Arch: mono (and msbuild which is also required) is in the extra/ repo, which is enabled by default. sudo pacman -S mono mono-msbuild
• Install additional required packages
  • Ubuntu: sudo apt install make g++ git libx11-dev libxfixes-dev mesa-common-dev
  • Arch: sudo pacman -S base-devel
    • If you're using X11 display manager you may need to install these packages: libx11 libxfixes
    • If you are not using the proprietary nvidia driver you may need to install mesa
• 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/UltimateDoomBuilder/UltimateDoomBuilder.git
• Compile UDB: cd UltimateDoomBuilder && make
• Run UDB: cd Build && ./builder
• Alternatively, to compile UDB in debug mode:
  • Run make BUILDTYPE=Debug in the root project directory
  • This includes a debug output terminal in the bottom panel
