Yes - I did get through the tests in the scripted chroot build of 20160527 with a 4.6.0 kernel - but after almost 2h45, and with the same three failures. The build then continued, until I noticed it had got through perl - by that stage a segfault in /bin/sh during the automake tests showed on the screen. The times on this box will be much longer (it's AMD, and old with slow memory and only SATA-2). I've now booted the revised 4.7 config but I haven't yet tried testing perl on the host. I've got a few things to do in spreadsheets, then I'll dig out a memtest86 CD. This is the box which for years has segfaulted when compiling with -j4, even building the kernel after a cold boot. I have/had a theory that perhaps the BIOS screws up the initialisation, so at the moment I'm dropping caches before doing any builds, and -j4 has been fine. Except, the repeat of perl was using -j1, but ISTR we force -j4 for the automake tests so I might have blown that theory. ĸen -- `I shall take my mountains', said Lu-Tze. `The climate will be good for them.' -- Small Gods -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
