To compile Octave, you will need a recent version of GNU Make. You
will also need GCC 4.3 or later, although GCC 4.4 or later is
recommended.
<p><strong>You must have GNU Make to compile octave</strong>. Octave's Makefiles
use features of GNU Make that are not present in other versions of make.
GNU Make is very portable and easy to install.
