This section is basically a longer explanation to the sequence of commands given in Quick start. If you didn’t have any problems during the Quick start steps, you want to have all the programs of Gnuastro installed in your system, you don’t want to change the executable names during or after installation, you have root access to install the programs in the default system wide directory, the Letter paper size of the print book is fine for you or as a summary you don’t feel like going into the details when everything is working, you can safely skip this section.
If you have any of the above problems or you want to understand the details for a better control over your build and install, read along. The dependencies which you will need prior to configuring, building and installing Gnuastro are explained in Dependencies. The first three steps in Quick start need no extra explanation, so we will skip them and start with an explanation of Gnuastro specific configuration options and a discussion on the installation directory in Configuring, followed by some smaller subsections: Tests, A4 print book, and Known issues which explains the solutions to known problems you might encounter in the installation steps and ways you can solve them.
