( i allready compiled the Jumbo-5, i make 2 version with MPI actived on both, 1 : macosx-X86-64 & 1 macosx-x86-sse2 ( for the speef of the MD5 ), MPI working on both ' mpirun -np 4 ./john..." ) NOTE : I don't take the risk to compiled on LION, cause to young OS & unstable for now...so i prefer make the stuff in Snow Leopard 1.6.8 I can re_compiled an news one's for sure. Ok, i take an look on the MaKefile & see : macosx-x86-64: $(LN) x86-64.h arch.h @echo "#define JOHN_BLD" '"'$@'"' > john_build_rule.h $(MAKE) $(PROJ) \ JOHN_OBJS="$(JOHN_OBJS) x86-64.o sse-intrinsics.o" \ ASFLAGS="$(ASFLAGS) -m64 -DUNDERSCORES -DBSD -DALIGN_LOG" \ CFLAGS="$(CFLAGS) -m64" \ LDFLAGS="$(LDFLAGS) -m64" May i have to "ADD" or "remove the existed value in = CFLAGS="$(CFLAGS) -m64" \ In the case i remove the existed value & add the one conform to your advices, that make that : CFLAGS="-mavx" \ = It is correct ? Concern, the fact to join the for "real" the John-users, it will be an plaisure for sure, but, i don't understand ( maybe my deffault English speacking missunderstand the sens, sorry) this is not the John-users-Mailling list ? can you give then some adivices & the way to take in this case. Thanks a lot for your help & support, Regards, Donovan
