gcc-4.3.0 fails to find mpfr.h on centos-4.5 (using gcc3 and gcc4)

Identical experience to my previous attempt on osx-10.5.2:

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.

BTW, I tried gcc4:
gcc version 4.1.1 20070105 (Red Hat 4.1.1-53)

To compile gmp and mpfr with gcc4 and then try again, same thing.

Re: gcc-4.3.0 fails to find mpfr.h on (centos and osx)

[Bill Broadley]

Sorry, false alarm on the centos, I had a typo, using -with-mpft instead of
-with-mpfr.

On OSX I found the config.log which has additional information:

configure:4542: checking for correct version of mpfr.h
configure:4573: gcc -o conftest -g -O2 -I/opt/pkg/gmp-4.2.2//include -I/opt/pkg/

So somehow the default architecture of gmp and mpfr aren't the same as what
gcc uses?
