LinuxQuestions.org - Finding path of GMP and MPFR for gcc upgrade

I'm attempting to update gcc to the latest build. I've downloaded and extracted the source to /tmp/gcc-4.3.0 and created a directory /tmp/gcc430 When I run /tmp/gcc-4.3.0/configure I get the following output

Code:

[root@localhost gcc430]# /tmp/gcc-4.3.0/configure

configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.

Try the --with-gmp and/or --with-mpfr options to specify their locations.

Copies of these libraries' source code can be found at their respective

hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/.

See also http://gcc.gnu.org/install/prerequisites.html for additional info.

If you obtained GMP and/or MPFR from a vendor distribution package, make

sure that you have installed both the libraries and the header files.

They may be located in separate packages.

I think I verified them as installed with rpm

Code:

[root@localhost ~]# rpm -q mpfr

mpfr-2.3.0-1.fc8

[root@localhost ~]# rpm -q gmp

gmp-4.2.2-4.fc8

But I need to know where they are installed so I can pass that to the configure command. Any suggestions are where they are or how to find out?

Thanks,
