[NetCDF] - Error encountered when creating a "NcFile" object

Without seeing the command line(s) used to compile and link your code,
I'd have to guess that you're missing one or more of the options:
-L/your/netcdf/lib -lnetcdf_c++ -lnetcdf
in the link step, where you should replace /your/netcdf/lib with the
directory containing the libnetcdf_c++.a and libnetcdf.a libraries. This
certainly applies to builds using GNU gcc (in this case, g++ for
compiling), and probably also applies to other compilers too.

If that doesn't help, I suggest you pass along the compile and link
command lines you're using.

Ok, this is what my code snippet looks like:



-------------------------------------------------------------------------
-------------------------------------------------------------------------
---- 
This shows the details of one of my constructors. It is located in
DatatSet.cc, 
it has a corresponding headerfile in DataSet.h and my executable is
called 'datatest'. 


/** Constructor #1 */
DataSet::DataSet( const char* fileName )   {
    NcFile coreData(filename, NcFile::Replace); 
    .
    . 
    .
    // end of constructor 
}

-------------------------------------------------------------------------
-------------------------------------------------------------------------
---- 



Now, the problem is that when I get to the 3rd line of code [ NcFile
coreData(filename, NcFile::Replace); ] the compiler goes nuts and gives
me the following error: 


-------------------------------------------------------------------------
-------------------------------------------------------------------------

DataGrid.o: In function
`DataGrid':/home/jstoup/WORK/trunk/DataGrid.cc:37: undefined reference
to `NcFile::NcFile(char const*, NcFile::FileMode, unsigned int*,
unsigned int, NcFile::FileFormat)'

int, NcFile::FileFormat)'

`NcFile::~NcFile()'
collect2: ld returned 1 exit status
make: *** [dataset_test] Error 1

-------------------------------------------------------------------------

Anyone have an idea as to why I am getting this linker error? 


help would be cool,

thanks
