Hi,
In addition to Jason's advice, you may also want to prepend your
LD_LIBRARY_PATH variable:
export LD_LIBRARY_PATH=$GCCHOME/lib:$LD_LIBRARY_PATH
where $GCCHOME represents your GCC install directory. If you do this
you need to make sure this is set every time you run an executable
compiled this way.
