Re: errors when using WRAPIT

Hi Sha,

The error:

   Symbol not found: _write_littler_onelvl_

might indicate that you have a spelling error in your Fortran function.

What does:

  nm write_littler_onelvl.so

report?

Also, can you try the small test mentioned in the "Troubleshooting" section of:

http://www.ncl.ucar.edu/Document/Tools/WRAPIT.shtml#TroubleShooting

The issue might also be with your version of NCL, and the version of the compiler you have now.
