I haven't built binutils pass 1 *from* 7.1 yet (just got to the end of chapter 6). Earlier this week I did a build of LFS svn 2017-05-01 from the same version, without tests, using -j8 except for binutils pass 1 (trying one of the symlinks that DJ has now added to LFS), so a really minimal build. That took 19m04 for my chapter 5 script (now 20m00), and 23m22 for chroot (now a net time of 24m02.
More details might follow if it builds enough of BLFS to try booting (but this time I'll definitely go back to chroot for most of BLFS, and I'm in no rush - this has to fit in when I'm not *using* the current system -- I live in a city. I know sparrows from starlings. After that everything is a duck as far as I'm concerned. -- Monstrous Regiment -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
