[Trilinos-Users] HDF5 - segmentation fault

[Antonio Cervone]

hi Andrea,
i tested your example and it is working for me, so the problem is in
the configuration/installation of your trilinos and hdf5 libraries.
you can try turning on epetraext examples and tests to see if they are working.
i used trilinos 10.12.2 and hdf5 1.8.9.
ciao

antonio
