This means that you need a simple way to extract the arch+model string from the runtime environment so that you can use it in make(1). A build is then started by saying something like: make buildworld HOST_MACH=i386-p3 or make buildworld HOST_MACH=alpha-ev5 In this scenario, building on Pentium III (BUILD_MACH=i386-p3) for use on an i386 (HOST_MACH=i386-i386), where the install happens on the i386 itself (BUILD_MACH=i386-i386) would do the right thing. The tools built on the P3 will not be used during installation by the i386 machine itself. Consequently, we need to make sure that during install we check and optionally build the minimal set of tools we need during installation. This solution is not undoable, but needs care to implement and can easily take weeks or maybe months to do it right. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
