I installed the compiler version of gcc-4.6.2 from sources,

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 --enable languages=c,c++,fortran,go make make install

however, when checking the version of gcc -version, version 4.7.2 is installed, which was installed earlier. How to switch between these versions?

    Probably you need to run gcc from $ HOME / gcc-4.6.2 - Vladimir Martyanov

specify in PATH the first path to your compiler

 PATH=$HOME/gcc-4.6.2/bin-наверное:$PATH;export $PATH
