I'm totally new with centos...we have a cluster in our labo with centos oscar. The gcc which was provided with the release is gcc41 and gfortran41. There are packages for gcc44 and gfortran44. I have installed them. But the gcc is not a link to gcc41 or gcc44. it is just an executable. idem for gfortran. So which is the good way on centOS to choose the gcc44 and gfortran44 per default.
Are you sure you did not update the packages instead of install...? To list the packages files : rpm -ql PACKAGENAME And check what is where...
