Jerry, can you please add the attached patch to fflas-ffpack and better yet if get it in upstream :-) I am working on linbox 1.2.2 patches, that also need -D__LINBOX_HAVE_INT64=1 in CFLAGS and CXXFLAGS (optional for 32 bit arches and sagemath), as that is not defined anywhere, and should be done either in configure.ac and autoreconf, or just set it in linbox.spec, but still trying to get all bits together to get things to compile and then check if everything works... Paulo
