This ONLY works for particular combinations of architectures and amd64 -> i386 is one of those pairs. i386 -> amd64 is NOT the same thing. > What should I do to build for multiple architectures? For mutually incompatible architectures, e.g. if you were doing amd64 to armel or i386 to mips, you need a cross-compiler toolchain and all the cross-dependency packages installed for the foreign architecture. Emdebian provides some, other sources exist but there aren't cross-compilers available for most combinations actually within Debian yet. amd64 -> i386 does NOT need any of that hassle, just a chroot. Simpler ways of doing this for all architecture combinations are awaiting the full MultiArch implementation. Typical list for queries related to incompatible architectures is debian-embedded@lists.debian.org Feel free to add this to the Debian Wiki, somewhere under the amd64 stuff. -- Neil Williams ============= http://www.linux.codehelp.co.uk/
