Installing Gnu Fortran and Eclipse on Macs

 

Installing GNU Fortran

You can either use MacPorts or use the binaries.

Installing 64 Bit Java (needed for Eclipse)

1. You need Java 1.7 or newer for Eclipse. You can download the latest version of Java from here:
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

The JRE should ideally be sufficient but Eclipse was not happy. So I installed the latest JDK from the above link.

Installing Eclipse

1. Help -> install new software ->
2. url - https://www.eclipse.org/downloads/packages/eclipse-parallel-application-developers/junosr1 ->
3. Select the appropriate version for your Mac.
4. If you get a build error "/bin/sh cannot find gfortran", you have to create a link to your fortran installation using:
   ln -s "source"/gfortran /usr/bin/gfortran
