Mohamed,These are missing library symbol errors. I suspect that you need to add this to the top of each program unit that has Netcdf calls:
use netcdfThis is because the Netcdf Fortran 90 interface uses modules. You can't properly link to the Netcdf F90 library without this declaration.
For diagnosis, your program is trying to link to this: __netcdf__nf90_openBut with a correct "use" statement it should be seeking a symbol named something like this (the name change may vary by compiler and platform):
___netcdf_MOD_nf90_openI might be wrong about all of this if you are on a platform or compiler that uses Fortran 90 linking conventions much different than what I am familiar with. If "use" doesn't fix it, then please provide identification and version info for your platform, compiler, and netcdf version.
