The mandatory Gnuastro dependencies are very basic and low-level tools. They all follow the same basic GNU based build system (like that shown in Quick start), so even if you don’t have them, installing them should be pretty straightforward. In this section we explain each program and any specific note that might be necessary in the installation.
The most basic choice is to build the packages from source yourself,
instead of relying on your distribution’s package management system. While
the latter choice is indeed possible, we recommend that you build these
dependencies yourself as discussed below. We will send out notifications in
info-gnuastro mailing list, see Announcements when we
find out that these requirements are updated.
