The problem that I'm experiencing seems to have been reviewed in these forums quite a bit but those solutions haven't solved it for me for whatever reason. My problem is that when I call ifort I receive a "command not found" response. I successfully installed the compiler and then called compilervars.sh ia32 but still nothing. I even tried creating a "custom.sh" file in etc/profile.d/ and then putting <install dir>/ifort but that didn't work either. Does anyone have an idea as to what my problem is? Thanks so much.
