I was trying to give you folks new numbers now that I seem to have my scripts almost in stone ... but I fell asleep for 12 hours (happens after all these 24+ hour marathons I do... programming, or doing this LFS stuff.. I tend to do that). For me, I've taken Barry's advice (He helped write the book so it might be his advice) Where is says these tests don't matter... I don't pay much attention. When the book says "Sanity Check - Run these tests - its critical? I just do it. Maybe I'll get daring after awhile and make a way to set a variable (export RUNLFSTEST=true) or something, and make the script make a decision on how it launches the makes and "configure" scripts. For now, I'm happy I can get the OS to compile and boot. I still have things I'm working on, but I'm pretty much overall pleased with the LFS book and the community. As for my gcc taking awhile, it is the tests and I didn't mean to exaggerate if I did - I would say its at least compile + testing .. around 45 minutes (double if I run twice because of errors) but that DOES include the testing which is what seems to take the longest. --Jason -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
