How to start the GNU Fortran compiler.

Posted 26 January 2013 - 03:38 PM

I just installed the GNU Fortran compiler on my MAC OS X machine. I seemed to install without any errors, with the message "The programs have been installed in /usr/local/gfortran/". How do I start this compiler? I can't find any directory named /usr/local/gfortran/!

Is GNU Fortran the best choice? I have a small legacy Fortran program that I would like to convert (and extend) to python.

Thanks, Jerry

If the installation was successful¹ you should be able to run the compiler simply by typing gfortran mycode.f (where mycode.f is your source file).

However if the installer says it installed to /usr/local/fortran and that directory does not actually exist, the installation probably wasn't successful.

gfortran --version


should confirm if it is installed. At least, it does from MSYS on Windows - assume it's the same command on OSX.

Thanks Sepp2k! It was as easy as that.
