Dear Tiziano
I thank you a lot for your help. I was able to compile the code although new issues have turned up.
I did the two available tests: the former related to the graphene transmission and the latter related to transport in a lithium chain.
The transmission calculation runs fine but it needs the same time both in serial and in parallel with 2 mpi procs. It is, instead, much slower with 4 mpi processors.
With the other test, the Lithium chain, I get a segmentation fault. The last lines printed are :
--------------------------------------------------------------------------------
KPOINTS| Number of kpoint groups 2
KPOINTS| Size of each kpoint group 1
KPOINTS| Number of kpoints per group 32
===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= PID 29677 RUNNING AT node165
= EXIT CODE: 11
= CLEANING UP REMAINING PROCESSES
= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault (signal 11)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

Could you please give me other hints?
