I installed gcc as described below.
it installed pretty well, but when I call
gcc -v it just shows the former version
gcc4.6.3. I do not know where to find the installation so that I can make a link to call it.
tar xzf gcc-4.6.2.tar.gz cd gcc-4.6.2 ./contrib/download_prerequisites cd .. mkdir objdir cd objdir $PWD/../gcc-4.6.2/configure --prefix=$HOME/gcc-4.6.2 make make install
All were done from my home directory.
