Re: [ESPResSo-users] H5MD file in espressomd

[Pierre de Buyl]

Dear Jiaxing,

This means that you have not built espressomd with the HDF5 library. When you
configure the code with cmake, it will list features that are found and if HDF5
is not found, H5MD will not be included. A more detailed error message was added
to espressomd recently.

To solve the problem, install HDF5 (parallel version) and re-run cmake and make.

Regards,

Pierre
