Hi Lawrence and Matt,

Thank you so much for your email. Thanks Matt, what can I do? I was wondering that the problem might be related to have installed most of the packages with both anaconda and directly on my computer. This is the output:

simone@simone:~$ ldd /home/simone/firedrake/src/h5py/h5py/defs.cpython-36m-x86_64-linux-gnu.so

Thanks, have a wonderful day.

Best regards,

Dear Lawrence,

Thank you for your email. Yes, of course.
Attached there is the "firedrake-install.log" while the output:

Hi Simone,

I think this can happen if you have 2 copies of HDF5 floating around, where one is compiled with MPI turned on and one isn't.

Ah. I wonder if you have a system install. We ask petsc to build hdf5 for us and then try and link against that.

Can you provide the output of

ldd /home/simone/firedrake/src/h5py/h5py/defs.cpython-36m-x86_64-linux-gnu.so

Thanks,

Lawrence
