Dear Dimitrios, from the FreeFem++ mailing list: http://ljll.math.upmc.fr/pipermail/freefempp/2013-July/002839.html we know now that Hypre was disabled by the developers for some reason. Now, from v. 3.25 it is possible to configure with the option "--enable-hypre" which correctly builds the hypre_FreeFem.so file. It worked for me. Kind regards. Giuseppe
