[netCDF #YUG-992413]: netcdf error when compiling

> U nc_open_mem
this only means that the fortran library references
that function. To see if it is defined in libnetcdf,
you would need to do something like this
> nm libnetcdf.a | grep nc_open_mem
and you should see something like this:
> T nc_open_mem
The U means uses, the T means defines.
But I can guess the answer. You appear to be using
libnetcdf 4.1.1, correct? The nc_open_mem and
nc_inq_path were were added after this version.
You will need to use a later version of libnetcdf.
I do not recall offhand when nc_inq_path was added
but nc_open_mem was added in an even later version.
If you can use the latest release, that is best.
