[netcdfgroup] Hello ???

[Roy Mendelssohn]

When you build netcdf, it puts certain options on the Fortran based  
on the compiler and platform.  From a terminal  (assuming your  
libraries are in /usr/local/lib) do:

nm -a /usr/local/lib/libnetcdff.a   | more      (this assumes that  
both libnetcdff.a and libnetcdf.a were created rather than just the  
one library)

then look to see how one of the undefined references in defined in  
the library - it probably has some combination of leading or trailing  
underscore, and when you compile anything that calls it it must have  
the same options set.
