Hi Russ,
thanks a lot. I did as you suggested. I buid ncdump/nccopy.c after
installing netCDF 4.1.1 but I have the following error. Probably
something is missing?
Thank you for the attention
Emanuele Cordano
You need to link libcurl (-lcurl).

Hi Emanuele,
I'm working in C with netCDF 4 and I'm searching a way of copying the
dimensions and the global attributes from a netCDF file to another one.
I was looking at the example program:
http://www.unidata.ucar.edu/software/netcdf/examples/programs/nccopy4.c
then I compiled the program and I linked the netcdf, hdf5_hl, hdf and z
libraries as I have usually done, but I received the following linkage
error related to the function nc_inq_typeid whose definition and content
are not found.
Oops, the function nc_inq_typeid() used by that example was not added
until after version 4.0.1 was released. If you try building with the
current release (4.1.1) or any subsequent release, that function is
included.
If you're going to use 4.1.1 or later, you could also just use the
ncdump/nccopy.c source for the nccopy utility included with that
release.
