On my current LFS-svn system (end of April), a true SBU is 209 seconds (i.e. remeasured after booting it, using make -j1). The book's llvm was recently extended to optionally include clang-3.0, I still build llvm without that and the way we used to, so I suppose your build might have decided to use clang instead of gcc for the C compiler ? Anyway, on my current system (Phonon x86_64, cpufreq ondemand controller running variously at 800,2200,2700,3400 MHz, recent 7200rpm SATA drive) using make -j1 and with all the gallium drivers, configure takes 5 seconds, make takes 7 minutes 16, DESTDIR install takes 8 seconds (all rounded to the nearest second). So for me, this time, that is 2.1 SBU (and 183MB). In passing, I notice that my current test build on my i3 (host LFS-7.1, make -j3 with the original SBU also using -j3 and not recalculated, with a multiplicity of cpu frequencies up to 3300) the recorded SBU was 3.9. Strange, but not worth me worrying. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
