I'm sorry you are having problems. The above is not an Amber error, but
is the result of trying to compile a simple 3-line fortran program, just
to check if your Fortran compiler is working.
Apple does not provide a default gfortran compiler, so you have to get
it, following the instructions at ambermd.org/Installation.php. It's
not clear from your email what you have done in this regard.
If you are following the suggested instructions, "which gfortran" should
return "/usr/local/bin/gfortran". Here is the program that the system
is trying to compile:
program testf
write(6,*) 'testing a Fortran program'
end program testf
You will need to consider carefully exactly what you did to install
gfortran, and see what (if any) are the error messages you get when you
try to compile the program above. If you can't figure it out, please
provide all fortran-related information, along with the version of OSX
you are using.
...good luck....dac
