Note: If using **i386** architecture, you can replace `libdsl1.2debian` with `libsdl1.2debian:i386` in the list above. On Debian, use `libjpeg8-dev` if `libjpeg-turbo8-dev` isn’t available in the package repositories. To be able to download maps from game servers when using Xonotic for online gaming, you will also need `curl` installed on your system.
