Hi,
well I have not yet used the pythonCGNS module with cgns v3.0. So I can
only guess, that the cgns library (so file) is compiled with hdf5
support but not linked to the hdf5 library itself. Thus there are
missing symbols. So either you link the cgns library itself to the hdf5
library, or you link the pythonCGNS module library additionally against
the hdf5 library. Therefore you'll need to adapt the setup.py file. Try
to change the following item in line 48
libraries=["cgns","hdf5"]
This is not tested, so maybe the syntax or the library is different.
Please report any success or failure to the mailing list.
Thx,
Oliver
