[lfs-support] Sanity Check Failed in GCC Pass 2
In conducting the sanity check in section 5.10:
echo 'int main(){}' > dummy.c
cc dummy.c
readelf -l a.out | grep ': /tools'
cc dummy.c
got the following output
/usr/bin/ld:
/mnt/lfs/tools/bin/../lib/gcc/i686-pc-linux-gnu/6.2.0/../../../crti.o:
unrecognized relocation (0x2b) in section `.init'
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
I am following LFS 7.10 RC1. I do not understand enough of the inner workings
of linking to debug this issue. The pages on google are seemingly directed at
experienced programmers--something which I am not.
What went wrong here?

What went wrong here?
Check lfs user's bash history to be sure that you run
the book's commands correctly. Check if you used the correct
tarball versions also. You can do this with command "history|less" on
a terminal as user lfs, or open /home/lfs/.bash_history with an editor.
If you don't find something, post some info for the host
and the output of version-check.sh

You should have stopped here. You can't just continue if you get errors.
You need to determine the cause of the problem before moving on.
However, I already see the problem (or at least one problem) - you're
running this as root instead of the lfs user. Run "rm -rf /tools/*" then
go back to the beginning of Chapter 5, and do everything as the lfs user
until you're told to do otherwise.

[lfs-support] powersaving with udev
Hi,
While researching how to get my laptop to save a bit more power in
battery mode
I found a great hint at
http://www.neowin.net/forum/topic/1106745-howto-powersaving-tweaks-with-a-udev-rule/
which will fit nicely into LFS section 7.4 .
The idea is to create a udev rules file like this...
cat > /etc/udev/rules.d/60-powersave.rules << "EOF"
SUBSYSTEM=="power_supply", ENV{POWER_SUPPLY_ONLINE}=="0",
RUN+="/usr/sbin/powersave true"
SUBSYSTEM=="power_supply", ENV{POWER_SUPPLY_ONLINE}=="1",
RUN+="/usr/sbin/powersave false"
EOF
...and then a powersave script. This will be called every time the power
supply is connected or disconnected.
cat > /usr/sbin/powersave << "EOF"
#!/bin/sh
case "$1" in
true) # Enable power saving settings on battery
#
# Device Runtime-PM
for dpcontrol in /sys/bus/{pci,spi,i2c}/devices/*/power/control; do echo
auto > $dpcontrol; done
#
# Disable nmi_watchdog
# echo 0 > /proc/sys/kernel/nmi_watchdog
#
# kernel write mode
echo 5 > /proc/sys/vm/laptop_mode
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
#
# disk powersave
hdparm -B 127 /dev/sda &> /dev/null
# for i in /sys/class/scsi_host/host*/link_power_management_policy; do
echo min_power > $i; done
#
# sound card powersave
# echo 10 > /sys/module/snd_hda_intel/parameters/power_save
# echo Y > /sys/module/snd_hda_intel/parameters/power_save_controller
#
# wlan0 powersave
# iwconfig wlan0 power on &> /dev/null
#
# cpufreq powersave
echo powersave > /sys/bus/cpu/devices/cpu0/cpufreq/scaling_governor
;;
false) # Return to default on AC power
#
# Device Runtime-PM
for dpcontrol in /sys/bus/{pci,spi,i2c}/devices/*/power/control; do echo
on > $dpcontrol; done
#
# Enable nmi_watchdog
# echo 1 > /proc/sys/kernel/nmi_watchdog
#
# kernel write mode
echo 0 > /proc/sys/vm/laptop_mode
echo 500 > /proc/sys/vm/dirty_writeback_centisecs
#
# disk powersave
hdparm -B 254 /dev/sda &> /dev/null
# for i in /sys/class/scsi_host/host*/link_power_management_policy; do
echo max_performance > $i; done
#
# sound card powersave
# echo 300 > /sys/module/snd_hda_intel/parameters/power_save
# echo Y > /sys/module/snd_hda_intel/parameters/power_save_controller
#
# wlan0 powersave
# iwconfig wlan0 power off &> /dev/null
#
# cpufreq ondemand
echo ondemand > /sys/bus/cpu/devices/cpu0/cpufreq/scaling_governor
;;
esac
exit 0
EOF
I've made a few changes to the original script and commented out some
other commands
to suit my computer configuration and my preferences, other users will
want to adjust
the file to their own needs.
A more detailed explanation can be found in the link above and in this
archlinux forum topic.

But I don't think I do anything for the sound or wifi. Do these make a significant difference ? My own laptop is actually a netbook, and so short of RAM that I don't think I'll ever rebuild LFS on it. But I'll try to remember this post when I eventually get a newer laptop, so thanks for mentioning these and providing the link.

But I've been using it for years. I think that powersave works on all current governors and all recent processors, but on intel (probably core and later, certainly SandyBridge and later) the preferred governor is pstate - and that doesn't do 'ondemand' (for SandyBridge and Haswell desktops, 'performance' appears to be satisfactory in terms of power drain, although the reported CPU frequency doesn't seem to drop down the way it used to). Similarly on AMD the pstate governor has been the default for some time - unless I'm mistaken. ĸen -- `I shall take my mountains', said Lu-Tze. `The climate will be good for them.' -- Small Gods -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

So, I gave up on trying to build a multilib toolchain. There is a working instruction from Armin to quite easily get a 32-bit glibc on a 64-bit lfs system. As I only needed a glibc to get my binary 32-bit brother printer drivers working, that was enough for me. If that is all you need, I can send you the instructions. If you however need more, I'm clueless as well.

Re: [lfs-support] bzip2: error while loading shared libraries: libbz2.so.1.0:
I did figure out what I did wrong - this was a consequence of not deleting source directories after chapter 5. I had to rebuild GCC to fix the error and ended up reformatting and rebuilding due to other errors. And I was using tar xvf - I had deleted the /tools directory. My statement that I was in Chpt. 6 was erroneous.

I'm sure Armin's instructions work, but whether somebody who has not yet successfully built LFS (plus whatever parts of BLFS appeal to him) has the experience to follow them seems unlikely. Building LFS for the first time is hard. Many people have trouble. And multilib is harder still (or perhaps just "more tedious", but "harder" is probably a better starting assumption). Cross-lfs may well be using older packages than LFS - they have even fewer developers and builders than we do - but to suggest they are "a few years behind" is an overstatement. In a cross-build it is not safe to assume that new versions of packages will just drop in without problems. Even in LFS we sometimes hit problems with newer versions. My suggestion to Rob is that he should build LFS, plus whichever parts of BLFS are useful to him. Perhaps more than once. the first time, do it manually, typing in the commands. After that, he should work out what went wrong, and *how* he can automate (script) his builds in a way that suits him. Most people will then need to learn what happens when their own take on scripting fails, but I will acknowledge that maybe he is more clever than I am, and can grasp that immediately, so that only one scripted LFS build is needed (I just wish, after using LFS for perhaps 12 or 14 years, that I had developed the ability to spot my own scripting errors before they break my builds). And after that, he should be in a position to either follow Armin's instructions for whatever 32-bit binary software he wants to use, or to follow cross-lfs for a full bi-arch system. ĸen -- `I shall take my mountains', said Lu-Tze. `The climate will be good for them.' -- Small Gods -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
