Hi Stefano,

Which version of HYPRE are you trying to use?

What is the contents of the directory /usr/local/Hypre/lib ?

How have you configured your HYPRE library?

In particular, was the --enable-fortran flag enabled when you ran 
configure for HYPRE? This is necessary for FLASH to use HYPRE.

You should also have another line:

FFLAGS_HYPRE = -I ${HYPRE_PATH}/include


Hope this helps,
