i dont think its finding the library but when i look at the netcdf.a
(using nm command) i can see the functions which could not be found.
during my googling i found two things related to such problems one has
something to do with added underscore to function names during
compilation and the other with the -i switch but i could stil not
solve the problem.
thanks alot for your help

'-L/usr/local/lib -lnetcdf' when linking.
