We will rely on the open-source gnu compiler for several of the computer languages that we will work with. The gnu C compiler is called gcc and the Fortran compiler is called gfortran. These tools should be installed on Aurora, so one way to use them is to work there. (You can either develop your files on Aurora using a text editor such as Emacs, or you can write them elsewhere and use a secure file transfer to move them.)
If you wish to work on your own machine, you will probably need to install the compiler there yourself. The steps are fairly straightforward for the Mac. Once you have completed them, the programs should be available from the command line Terminal.
On Windows the installation takes a bit more effort. You will install a package called Cygwin, which includes a number of Unix-like tools, plus a bash shell that provides a command line alternative to the standard Windows command prompt. You can download the setup file for Cygwin to start. Accepting the default options will take you through a number of screens until you get to the package selection page:
Here you want to make sure that the View is set to Full, and enter gcc in the search box. You should see lines for gcc-core and gcc-fortran in the listing; click on these and make sure that they are set to install. You should also install ocaml and possibly clisp. If you feel like it, you can also browse through the other options available and select any that you would like to add. There are some excellent and useful utility programs to perform file conversion, for example. When you are done select Next to continue the installation. It may take some time to complete. When it is finished, you should find the Cygwin 64 Terminal in your start menu. Run this to get the command prompt. The command cd /cygdrive/c/Users will take you to the Users directory. From there you should be able to navigate to the location where your program files are stored.
