Compiling GCC 4.6.3 on Fedora 18
This guide assumes a 64 bit architecture First get gcc 4.6.3
Extract the tar
tar -xvf gcc-4.6.3.tar.gz
Install wget (required by prequesites command), development tools and 32 bit glibc headers
yum install wget glibc-devel.i686
yum groupinstall "Development Tools"
Enter the directory, download prerequisites and run configure with prefix to set the install directory, change this to your liking
cd gcc-4.6.3/
./contrib/download_prerequisites
./configure --prefix=/usr/local/gcc/4.6.3
A compilation error will result when you run make so either apply the following patch or change the lines modified by the patch
patch -p1 < {/path/to/patch/file}
OR
nano gcc/config/i386/linux-unwind.h

Next if we want this version to be the default we put the following in out .bashrc file
export PATH=/usr/local/gcc/4.6.3/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/gcc/4.6.3/lib64:$LD_LIBRARY_PATH
