Hi Namu
For the record, I am not a C++ programmer.
This is all I can do to help.
On CentOS 7.5, with the same libraries as you,
I get the same errors.
It looks like libnetcdf_c++ is the legacy/obsolete version.
'yum info' shows this:
Description : Legacy netCDF C++ library. This library is provided
for backward
: compatibility only. New C++ development should
be done with the netCDF
: CXX4 C++ library.

But unfortunately that is the one available in Red Hat/CentOS 7.
The new interface is libnetcdf_c++4.
You point to it in your compilation command, but you don't have that
library installed.
Unfortunately I couldn't find the libnetcdf_c++4 for RedHat/CentOS 7
on epel, which is too bad.
However, on Fedora Core 26, with libnetcdf.so.11.0.4 and
libnetcdf_c++4.so.1.0.3 the program compiles fine.
So, I guess this problem is really a matter of having only
the obsolete libnetcdf_c++ library.
I hope this helps,
Gus Correa

On RedHat 7, using yum, I installed netCDF4 C and C++ libraries:
$ ls /usr/lib64/*netcdf*
/usr/lib64/libnetcdf_c++.so /usr/lib64/libnetcdf.so
/usr/lib64/libnetcdf_c++.so.4 /usr/lib64/libnetcdf.so.7
/usr/lib64/libnetcdf_c++.so.4.2.0 /usr/lib64/libnetcdf.so.7.2.0
$ ls /usr/include/*netcdf*
/usr/include/netcdfcpp.h /usr/include/netcdf.hh
/usr/include/netcdf.h /usr/include/netcdf_meta.h
I am trying to compile the code:
#include <iostream>
#include <netcdf>
using namespace std;
using namespace netCDF;
int main()
{
return 0;
}
using:
g++ -o test test.cpp -I/usr/include -L/usr/lib64 -lnetcdf_c++4
-lnetcdf -lm
but get the error:
fatal error: netcdf: No such file or directory
#include <netcdf>
^
compilation terminated.
I tried using netcdf.h and netcdfcpp.h. This gives me the error:
error: ‘netCDF’ is not a namespace-name
using namespace netCDF;
error: expected namespace-name before ‘;’ token
using namespace netCDF;
I'll appreciate any help in trying to get this working.
Thanks,
Namu
