Maybe I am lucky:-), I set MAKEFLAGS='-j 2' on my E7400 double cores CPU, no any exception appeared until I finished all the packages in Chapter 5. But, I think this should depends on the quality of the package itself. Maybe, after the next release of a package, it will refuse to do a parallel make or parallel make install just like you have experienced. -- littlebat -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
