Hi, I am trying to install force-fortran complier (http://sourceforge.net/projects/osxforce/files/)on my macbook (Macbook air, 2011, OSX Yosemite, version 10.10.4). When I tried to install it, it said "quit unexpectedly" and I failed to install it. This compiler has been tested on OSX leopard so I am not sure if it also works for yosemite. I really need help to get this compiler installed. Also, does anybody know what's the difference between gfortran and force-fortran compiler? (I have installed gfortran but it seems that it cannot fully open code that is already built on PC). Any help will be greatly appreciated!!
