Thinking my best hope of programming was with Python or Fortran, I eventually
decided to utilize C/C++. Thus, a C/C++ interpreter would be the best
environment in which to learn to program, using COMSPARI as my model.

> Why not Fortran, being 'English lilke'?  The Fortran folder contains many .c
files. If netCDF were from 1975, how many .c files would be in the Fortran
folder? I just need to discover what is needed to compile a C/C++ interface.
AstroROOT has done this for FITS files, there are support questions and
software available that allows HDF5 files to be used in ROOT. The netCDF4
combination with HDF5 seems a natural evolution of what I am trying to do.

the ncopts problem that is discussed in many support requests.

Using the CXX folder and copying and pasting the C folder in there, plus
config.h from the first directory, I got it to work--but only once. Using that,
originally built as a shared lib as the handmade make file explains, I could
compile, link and pass the nctst program. I am not sure why it no longer works
and working on trying to discover if it worked originally because I ran
./configure on my Linux before trying the ROOT integration.

would actually be the contents of att.c) and just need to generate a dictionary
using rootcint and the required netCDF header files, then compile those G__.cxx
and G__.h files. Then get the ANDI interface to work.

ms10io.c ms10aux.c ms10enum.c ms10.h ms10io.h CAN compile unchanged with g++.
But the ROOT interpreter declares ncopts undeclared and will not load the .so.

But why don't you just build the netCDF C++ library with the usual
configure/make commands, and let the netCDF configure script figure out which
files you need.

The fortran API is in fact implemented with C. Sounds funny, but there it is.
If you want to use fortran, it will work. If you run configure with
--disable-f77 then both the Fortran 77 and Fortran 90 APIs will be skipped in
the build.

Just build netCDF in the usual way and you will get a netCDF C++ library:

./configure && make check

Good luck,

Ed
