./configure --libsconfigure—libs="-lmpfr -lgmp"

./configure --prefixconfigure—prefix=/home/myname/apps

The first line includes the <code>mpfr</code> and <code>gmp</code> libraries. The second line tells [[make (software)|make]] to install the final version in <code>/home/myname/apps</code>. The <code>INSTALL</code> file contains instructions should the prescribed steps fail.
