How do I know if I have ifort installed on my Mac (Snow leopard)?

I have a program that need to be installed with the "gfortran/ifort" compiler. I have a Mac OSX 10.6.8 (Snow Leopard). I know I have gcc installed, because I installed my self (from the gcc package inside the Xcode installer, so I did not have to install the whole xcode), also after typing in the terminal "which gcc" I get the directory.

I also installed gfortran from gnu and after typing in the terminal "which gfortran" I get the directory.

However, since I am learning in this process, I am not sure if when I installed the gfortran the "ifort" is also installed or I have to install it my self as well. How can I check if ifort is install? If it is not install, where can I get it from for Snow Leopard? Can it be installed if I installed the whole xcode and then the "command line tool"?

ifort is the usual short name for the Intel Fortran compiler. You know you have it installed if any of the following is true:

  1. When you type ifort at a terminal command line you get a response such as ifort: command line error: no files specified ...
  2. The XCode Build Settings for a Fortran project include lists for items such as Intel Fortran Compiler ... Code Generation.
  3. You can find an executable called ifort somewhere on your disks; it's usual location is in /usr/bin but you might have installed it elsewhere.

Note that it is possible that you have it installed but can't use it because you don't have a licence. Intel Fortran costs money, the way to get a copy is to buy it either directly from Intel or from your local reseller.
