Many programs come in source format, often in tar.gz form. First,
you must unpack the tar.gz file; for details on doing this, see
section 10.3.1 on page [*]. Before you can compile the package,
you’ll need to have gcc, libc6-dev, and other relevant “-dev”
packages installed; most of these are listed in the devel area in
dselect.
With the appropriate packages installed, cd into the directory that
tar created for you. At this point, you’ll need to read the
installation instructions. Most programs provide an INSTALL or
README file that will tell you how to proceed.
