Hi,
I am trying to install NetCDF on my Ubuntu 18.04. for C++ to use 
.nc-files in my code for further calculations. Until now, I have 
installed curl, zlib, hdf 5 and the actual version of NetCDF-C 
(netcdf-c-4.6.2).
I have tested NetCDF-C on an example file (simple_xy_wr.c from 
https://www.unidata.ucar.edu/software/netcdf/examples/programs/) which 
compiles and runs without any problems.
After that, I wanted to install NetCDF for C++. Therefore, I downloaded 
the actual library (netcdf-cxx4-4.3.0.) and tried to configure the 
unpacked library by following command:
./configure --prefix=$fld_install --enable-cxx-4 ($fld_install is my 
directory where I want to install NetCDF-C++)
Unfortunately, I receive following warning after configuring the library:
configure: WARNING: unrecognized options: --enable-cxx-4
The same error occurs by trying –enable-netcdf-4.
After installing the library with the make & make install procedure, I 
can not compile any C++ code which contains some NetCDF-C++ -Data 
Structures.
I am not able to find any error in my approach and are pretty sure that 
my paths of NetCDF-C are set correctly. Maybe I got a wrig version 
combination of NetCDF-C and NetCDF-C++ or forgot something by 
configuring the libraries.
I would be very thankful for any help or hint of you where I have made a 
mistake by installing NetCDF-C or NetCDF-C++. Thank you for your help in 
advance.
With best regards
Markus
