undefined reference using netcdf library

[Yair suari]

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
