Re: wrapit and cygwin updates?

Hi Joseph,

Unfortunately I haven't done anything with this. I keep meaning to see if there's some kind of documentation on creating shared objects with Cygwin.

You don't *have* to use WRAPIT to created shared objects. WRAPIT just removes all the intermediate steps of creating the *.so.

In general, the intermediate steps are:

 1. Create the wrapper C file:

      wrapit77 < your_fortran_file.f > WRAPIT.c

 2. Compile the Fortran file:

    gfortran -fPIC -v -c -fno-second-underscore your_fortran_file.f

 3. Compile the wrapper C file:

    gcc -c -fno-common -I$NCARG_ROOT/include WRAPIT.c

4. Create the *.so file:

    gcc -bundle -flat_namespace -undefined suppress WRAPIT.o your_fortran_file.o -o whatever.so -lgfortran

The #4 step is the one that's the problem. The above step is for a MacOSX system. For Cygwin system, maybe this will help:

Good luck,
