Which is the one in: /usr/obj/usr/src/gnu/usr.bin/binutils/strip and not the one in: /usr/obj/usr/src/i386/usr/src/gnu/usr.bin/binutils/strip Are we still talking about the same strip(1)? > > In short: Do not not build on Pentium with -march=pentiumsomething and > > then later install on non-pentiums! > > Uh, how can cross-builds _possibly_ work then????

No, that's not wrong. Just think about it for a moment. You need to build cross tools first. Those must run on the build machine. You therefore build those exactly as you build anything else: you use the libraries on that machine. After you have built your cross tools, you can start building non-native libraries, against which you link the final non-native binaries. -- Marcel Moolenaar mail: marcel@cup.hp.com / marcel@FreeBSD.org tel: (408) 447-4222 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-qa" in the body of the message
