gfortran linking errors on OS X 10.9

gfortran linking errors on OS X 10.9

(OP)
Greetings All,

I am new to the forums here and hoping to find some assistance from folks that have experience with compiling older FORTRAN code on OS X.

I am using the gfortran compiler on Mac OS X 10.9.5 with Xcode version 6.2 and the Xcode command line tools installed. I am performing the compilation and linking from the command line/Terminal (i.e. not using an Xcode project).

Here's what I've got:

RE: gfortran linking errors on OS X 10.9

It would've been nice to see you put some minimal effort, research towards solving this problem.

You really need to look at date() and timer() and see how you can replace them with what may be available now (date_and_time()?).
