Thiemo Seufer <ica2_ts@csv.ica.uni-stuttgart.de> is working on it; it's quite an effort to get it right so if you want to work on this you should probably team up with him. > And if binutils are broken that means kernel is 32-bit as well? Yes but that's more a feature than a bug. All intra-kernel references are now only 32-bit therefore we've got more compact, faster code as result. The boot file is a 64-bit ELF kernel, though. That's because the ARC firmware of the Origin will accept nothing else so we cheat by converting the 32-bit vmlinux into a 64-bit file using objcopy. > Anyway 32-bit applications should run pretty fine? Most of them. Now and then we find bugs in the binary compatibility code but these are usually easy to squash. Ralf
