Dear Liping,
I believe the following error message that you got:
> fatal:syntax error: possibly an undefined procedure
is the key to why this isn't working. The
"at_t_test_time_spatial_bylev" apparently is not defined anywhere,
and thus it doesn't know how to call it.
I can tell from the syntax of this line that you are trying to load a
shared object. With this in mind, there
could be a few things wrong:
1. You haven't created the appropriate shared object.
2. You've created the shared object, but you are not loading it with
the NCL "load" command.
3. The subroutine "at_t_test_time_spatial_bylev" is not in the *.f
or *.f90 file used to create the
shared object (check your spellings).
4. You are using "g77" to compile the shared object, and because of
the underscores in your
subroutine name, "g77" is appending an extra underscore in your
*.so file, and thus causing
NCL not to see your subroutine. If this is the case, try
compiling the Fortran routine with the
-fno-second-underscore option (this may not be the exact option
name, I'm naming it from
memory).
Please email me separately if you have any questions.
