Re: mpfr issues when Installing gcc 3.4 on fedora core

I am wondering if my all my troubles stem from mpfr not being
installed properly ..
When I configure mpfr I get the following warning. Cud this be an issue ?

checking if gmp.h version and libgmp version are the same... (4.2.1/4.1.4) no
configure: WARNING: 'gmp.h' and 'libgmp' seems to have different versions or
configure: WARNING: we cannot run a program linked with GMP (if you cannot
configure: WARNING: see the version numbers above).
configure: WARNING: However since we can't use 'libtool' inside the configure,
configure: WARNING: we can't be sure. See 'config.log' for details.

And as matt suggested if mpfr is not needed by 3.4, how can I configure it that way. --disable -mpfr did not help.

thanks for all the hints so far

I don't think MPFR install libs in .../lib64 (everytime I tried on an
x86_64 machine, it didn't, but I was using another prefix directory,
in my $HOME). Anyway, MPFR is based on the autotools. So, it would be
a problem with the autotools. But you can change that with the --libdir
configure option:

--libdir=DIR object code libraries [EPREFIX/lib]
