F2c

While not really a compiler, f2c is based on the UNIX FORTRAN compiler, but as it used the same backend as the C compiler, f2c emits C, which in turn can be compiled by the native compiler.

F2C can be downloaded from http://www.netlib.org/f2c/

installing

F2c is easy to install, you can download the source here: http://vpsland.superglobalmegacorp.com/install/f2c/f2c.tar.gz

Simply extract and run:

make -f makefile.u

Then run:

cp f2c /usr/local/bin
cp f2c.h /usr/local/include

If all went well you should have a f2c command.

Next you'll need to download and build the IO library http://vpsland.superglobalmegacorp.com/install/f2c/libf2c.zip

Simply extract and run:

make -f makefile.u

Then run:

cp libf2c.a /usr/local/lib

Now you should be able to build a simple FORTRAN program like this:

hello.f

      program hello 
      print *, 'Hello!' 
      end

Then run:

bash-2.01$ f2c hello.f 
hello.f: 
   MAIN hello: 
bash-2.01$ cc hello.c -lf2c -o hello 
bash-2.01$ file hello 
hello:  Mach-O executable (for architecture m68k) not stripped 
bash-2.01$ ./hello 
Hello!
