A slightly longer explanation of what I was thinking: - There's a new round of 'make -j' problems lurking in there. We are missing chunks of the ordering glue that cause libraries to be built in the right order when they depend on each other. - It's a waste of cpu time for the usual case, particularly for the 11.x cycle for the next 1-2 years. - We don't build them properly - we invent cpu flags etc. The usual use case for 32 bit binaries seems to be: - running a 32 bit chroot or jail - this is unaffected. - running old binaries, usually from 4.x or 6.x when the 64 bit port was really green - WITH_LIB32 doesn't actually help much with this because most of the libraries are missing. It seems more likely we can do a better job with packages. With some massaging, we should be able to use the compat-6.x/i386 libraries as-is, and solve the "old 4.x/6.x binary" issue in one go. However, ld-elf32.so.1 does require special handling. I have something in mind that might make this moot though. I suspect I've made the powerpc folks angry though... -- Peter Wemm - pe...@wemm.org; pe...@freebsd.org; pe...@yahoo-inc.com; KI6FJV UTF-8: for when a ' just won\342\200\231t do. <brueffer> ZFS must be the bacon of file systems. <brueffer> "everything's better with ZFS"
