Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations. Source code for these libraries 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, MPFR and/or MPC 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.

how to install gcc & compiler on CentOS6.2!?

Postby pschaff » 2012/01/24 19:01:22

Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.

Please read about Installing Software and Repositories, and note the warnings and advice about installing and configuring the yum priorities plugin. Non-core repos should have a higher numeric value, which is a lower priority. Lower is "better" as in golf scores.

Please pay particular attention to the evils of Source Installs. Source installs as root are particularly dangerous.

See also FAQ#20. Where can I get the latest version of XyZ.rpm for CentOS? I cannot find it anywhere.

If you need later packages for such fundamental things as gcc then either use Fedora, possibly via virtualization, live with what is available, find an earlier version that does work, or fix the software for compatibility with EL6. If you need help building something then please post details of that in a new topic.

I do note that Fedora 14 has gcc-4.5.1-4.fc14.src.rpm. One could attempt to rebuild the Source RPM, but I can't say that is really recommended, and would certainly recommend not going too far down that road if replacing other core packages/libraries is required to make it work.

Why do you need a later GCC?
