Hi,

Sorry it has taken so long to respond to your question.

These missing class methods, NcFile::get_dim() and NcDim::size(), are defined in
the netCDF C++ library, but the options to the g++ compiler don't specify where
that library is installed.  For example, if it was installed in 
/usr/local/lib/libnetcdf_c++.a, 
then there should have been "-L/usr/local/lib -lnetcdf_c++" on the g++ command
line.  Perhaps the netCDF C++ library is not installed on your computer.  If it 
has been
installed, you'll have to specify where it is in the Makefile for rnnlib or to 
it's configure
script.
