Hi Wei Hou, 

did you enable parallel execution of hdf5 with --enable-parallel? Under <3.2.2 Compile> on https://gitlab.psi.ch/OPAL/src/wikis/For%20Developers/Compile-OPAL you find scripts that compile all necessary libraries with the correct configuration. 

Cheers 

Christof

Hi Wei Hou I forward this to Achim, he is the master mind

w.r.t. H5hut. I understand correctly that you compiled  successfully

hdf5, now question is always does the H5hut build find your compiled version.

@ Achim please have a look at his output. Any idea?

Please send such questions always to opal AT lists.psi.ch, then many more

colleagues are confronted with the problem.

Cheers A

Hi,

Guten tag.

I am having some troubles in compiling H5hut.

I followed the guide in OPAL wiki to compile parallel version of hdf5-1.10.3.

However, configuring H5hut always result in the following message

checking checking whether hdf5 lib supports parallel IO... no

checking for lustre API ... 

checking looking in /usr ... ... no

checking looking in /usr/local ... ... no

checking looking in /usr/local/lustre ... ... no

checking looking in /opt/lustre ... ... no

configure: WARNING: Couldn't locate the lustre API... building without support for lustre striping!

checking if C interface enabled... yes

checking if fortran interface enabled... no

checking if python interface is enabled... no

checking if large indices are enabled... no

checking if parallel interface enabled... yes

configure: error: hdf5 does not support parallel IO!

Have you or some of the OPAL users encounter similar situations before ?

I include Philippe in this email so that he is aware of the situation.

Danke gut.

Regards

Wei Hou
