I build the cross-compilers as part of a host make world during which they never get executed. To build a cross-world, I just set MACHINE and MACHINE_ARCH and let sys.mk (more pollution 8-) check to see if these differ from what the kernel knows. If they differ, sys.mk sets CC etc to my cross-compiler and HOST_CC to cc. Then the make world uses NOTOOLS and DESTDIR. The few places in our tree where we build host tools in the obj tree during make world and execute them from there need simple makefile changes to use HOST_CC instead of CC. I don't think that cross-compilation helps solve the bootstrap/upgrade problem caused by the signal changes. -- John Birrell - jb@cimlogic.com.au; jb@freebsd.org http://www.cimlogic.com.au/ john.birrell@opendirectory.com.au To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
