[netCDF #XEI-893423]: Problems while linking

Hello,

This is an interesting issue.  What are you trying to build, when the linking 
fails? You mention that the linking to netcdf_c++4 is failing, but libnetcdf is 
the core C library, not the C++ interface.  If the issue is at runtime, you 
might need to update your LD_LIBRARY_PATH to reflect the location of the 
libraries; this is used by the runtime to load the library at, well, runtime.  

So, if I understand correctly, the issue occurs when you run the program, and 
it is  runtime load error for the C library.  Try setting the LD_LIBRARY_PATH 
environmental variable when running, and let us know what happens.

Thanks!
