f2c

[Chris Jones]

Hi,

I think you might be going about trying to install this the wrong way. ratfor appears to only need f2c, if it cannot find a working fortran compiler, so you just need to give it one. By default it searches for 'f77', but you can change this by setting the environment variable F77. S0..

1. Install a MacPorts fortran compiler. For instance 'gcc46'. 

 > sudo port install gcc46

This provides the compiler 'gfortran-mp-4.6', so then all you need is

Chris-Jones-Macbook-Pro ~/Downloads/ratfor-1.01 > export F77=gfortran-mp-4.6 
Chris-Jones-Macbook-Pro ~/Downloads/ratfor-1.01 > ./configure
