I am relatively new in fortran and also new in this forum. Please forgive me if my question does not make any sense to you.
My problem is,
I am trying to retrieve HWM14 model data (model output)by running fortran script (hwm14.f90) for the Horizontal Wind Model version 2014 (HWM14). I got an error at the very beginning and could not get the script running further. Could anyone please help me why I am getting this error and how I fix it. The error is saying 'undefined reference to WinMain@16'. I am not sure what the problem is. I have attached the lines of error message as below.
$ gfortran hwm14.f90
/usr/lib/gcc/i686-pc-cygwin/5.4.0/../../../libcygwin.a(libcmain.o): In function `main':
