The Hitch Hiker Linux source code is available as an xz compressed tarball from the hitchhiker-linux.org website, or can alternatively be cloned from the main git repository.
The current stable source tarball can be fetched using wget:
wget -c https://hitchhiker-linux.org/pub/stable/src/src.tar.xz tar -xJf src.tar.xz
Alternatively, should one wish to build the most recent development version of HitchHiker, the source can be checked out via git over https.
git clone https://git.hitchhiker-linux.org/hitchhiker/src.git
Currently, the build tree expects to be located in the top level directory /src, and it is therefore necessary to either
cd /prior to running the previous commands, or else to bind mount the actual source directory onto /src prior to building. This requirement may be changed in the future in order to increase flexibility.
