I'm subscribing to R-devel, where may be the proper place to post this query. Sorry. I have a reason to create R from the source code. I have a MacBook Pro running OS X 10.8.2. I've downloaded 'gfortran-4.2.3.pkg' and installed Fortran. I downloaded R-2.15.3 and tried to do a "./configure". The configure fails and the error messages I'm seeing are: checking for dummy main to link with Fortran 77 libraries... none checking for Fortran 77 name-mangling scheme... unknown configure: WARNING: unknown Fortran name-mangling scheme checking whether gfortran appends underscores to external names... unknown configure: error: cannot use Fortran I've read the admin manual. My Mac system is vanilla, so I had been hoping that I'd have no difficulty generating R but unfortunately I was wrong. Can someone suggest something for me to try?
I suspect you forgot to set -arch and the architecture of your fortran and gcc doesn't match. Please see the Mac FAQ and use the proper flags or update your Fortran (so you have a 64-bit driver as well). Cheers, Simon
