Well, it *can* be halved. My setup: 486/66, 32 MB, EISA/VLB, SCSI disks on a BT747 controller (Quantum Empire 2100 for the srcs, Fujitsu 500MB whatnot for obj), cflags -O2 -m486 -pipe, not building profiled libraries. It takes less than 7 hours for a make world with virgin source and obj trees, maybe 20 min more if there was a make world before. Now I've noticed that subsequent 'make all install's will relink all the programs. I suppose this is due to the libraries being newer than the existing objects. However, this wouldn't be necessary unless the shared lib version has gone up. How hard would it be to get rid of this behaviour? I don't want to go and dig myself up to the armpits into the make stuff if it's impossible :-) Michael-- Michael Elbel, Digital-PCS GmbH, Muenchen, Germany - me@FreeBSD.org Fermentation fault (coors dumped)
