[netCDF #PKX-997551]: Build NetCDF using Intel ifort in Linux

Hi,

> I am trying to build NETCDF 4.1.3, then linking to it from a Fortran

> 
> ifort -o gswp2data_my gswp2data_my.F90 -I/usr/local/netcdf/include 
> -L/usr/local/netcdf/lib -lnetcdf
> 
> Fortunately, the data in the nc file can be obtained correctly.
> 
> Then I transplant the code into another fortran program. This program

The statement above looks wrong.  Maybe it should instead be:

  LDFLAGS     =   -lm -L$(NETCDFLIB) -lnetcdf

I don't know, but make sure the Fortran units that call netCDF functions each 
have a

  use netcdf

statement in the declarations.  Also, you must be using the same Fortran 
compiler as
was used in building the netCDF library, because the Fortran-90 module files are
different for different Fortran compilers.
