The concept of matching 'make -j X' to the number of cores isn't difficult, but I'd argue it's worth a mention as much for those who haven't had cause to wonder about 'make's various flags before, as to give people a lesson in multi-core theory: in my own case, as a Linux user for several years now, make -j was an eye-opener when I came across it only yesterday, since I had never had a SMP or multi-core system until very recently upon which to compile, and thus unwittingly filtered out from my Linux knowledge the make flags which didn't have any use to me, until now. In short: say it for those who lack 'make' knowledge, as well as those who lack 'multi-core' knowledge. -Deskin Miller -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
