In order to build successfully, I installed the rpm mentioned below, and also the 32 bit version of gmp. up2date --get gmp-4.1.4-3.i386.rpm rpm -i /var/spool/up2date/gmp-4.1.4-3.i386.rpm Then I compiled both 64- and 32-bit versions of mpfr. I had some difficulty because I chose to install mpfr in /usr/local/lib and /usr/local/lib64. When instructing 'configure' where to find the mpfr library, you don't get to specify BOTH directories; I fooled it with the following configure command: ../gcc/configure --prefix=/usr/local/encap/gcc-4.2.0.0 --program-suffix=v42 --enable-languages=c,c++,fortran --with-mpfr-lib="/usr/local/lib -L/usr/local/lib64" --with-mpfr-include=/usr/local/include This seems inelegant, is there a proper way to do this that I failed to understand from the installation instructions?
