[netCDF #LTO-228407]: difference between "-lnetcdf" and "-lnetcdff" ?

Greetings Jatin!

The extra 'f' in the -netcdff refers to the fortran library, whereas -lnetcdf 
is the c library.

Check out

http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-f90/Compiling-and-Linking-with-the-NetCDF-Library.html

and

http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-fortran-install.html

for some more details as to why the two exist (short answer - they are shared 
libraries).

The netCDF tool nc-config will tell you what you need to use when linking to 
the libraries:

For C code:

nc-config --libs

and for FORTRAN code:

nc-config --flibs

Cheers!

Sean

> Hi,
