[SOLVED] Lm-sensors on Corepure64 5.x

[fodder]

I am having trouble getting lm-sensors to work on Corepure64 5.1.  Using lm-sensors on TC 4.x x86 on this same computer I am able to access the temperature sensor so I don't think it is hardware related, but am certainly not sure.

For starters, here is how I am booting into Corepure64:

• Boot LiveCD CorePlus 5.1 with Installation and create bootable USB (Frugal, Whole Disk, ext4, Core Only)
• Boot to USB and run the following commands:
  
  • wget -qO - http://tinycorelinux.net/5.x/x86_64/release/distribution_files/vmlinuz64 > /mnt/sda1/tce/boot/vmlinuz64
  • wget -qO - http://tinycorelinux.net/5.x/x86_64/release/distribution_files/rootfs64.gz > /mnt/sda1/tce/boot/rootfs64.gz
  • wget -qO - http://tinycorelinux.net/5.x/x86_64/release/distribution_files/modules64.gz > /mnt/sda1/tce/boot/modules64.gz
  • tce-load -wi nano
  • Edit /mnt/sda1/tce/boot/extlinux/extlinux.conf to be:
    DEFAULT Corepure64
    LABEL Corepure64
    KERNEL /tce/boot/vmlinuz64
    APPEND initrd=/tce/boot/rootfs64.gz,/tce/boot/modules64.gz quiet waitusb=5:UUID="000...000" tce=UUID="000...000"
    
  • wget -qO - http://mydomain.example/empty.txt > /mnt/sda1/tce/boot/onboot.lst
  • rm -rf /mnt/sda1/tce/optional/*.*
• Reboot without backup and run:
  tce-load -wi aterm fltk-1.1.10 Xlibs Xprogs flwm wbar Xorg-7.7
  startx
  

At this point everything appears to be a correctly running install of Corepure64 5.1.  For example, I can see a full 8 Gigs of memory listed as usable.

Then, I do the following to try and install lm-sensors:

• First, install all dependencies, grabbing libiconv from 4.x x86_64 repo:
• tce-load -wi compiletc squashfs-tools perl5 hwmon-3.8.10-tinycore64
• wget -O - http://ftp.vim.org/os/Linux/distr/tinycorelinux/4.x/x86_64/tcz/libiconv.tcz > /mnt/sda1/tce/optional/libiconv.tcz
• wget -O - http://ftp.vim.org/os/Linux/distr/tinycorelinux/4.x/x86_64/tcz/libiconv-dev.tcz > /mnt/sda1/tce/optional/libiconv-dev.tcz
• tce-load -i libiconv libiconv-dev
  
  
• Next, download and build lm-sensors:
• wget -O - http://dl.lm-sensors.org/lm-sensors/releases/lm_sensors-3.3.4.tar.bz2 > lm_sensors-3.3.4.tar.bz2
• tar -xvf lm_sensors-3.3.4.tar.bz2
• cd /home/tc/lm_sensors-3.3.4
• make all
  
  
• Last, create TCZ and install:
• make DESTDIR=/tmp/lm-sensors install
• mksquashfs /tmp/lm-sensors/ /mnt/sda1/tce/optional/lm-sensors.tcz
• tce-load -i lm-sensors

There do not appear to be any make errors, but when I try and run "sudo sensors-detect" I get:
sudo: unable to execute /usr/local/sbin/sensors-detect: No such file or directory

However, that file does exist and the /tmp/tcloop/ that it points to also exists.

I also tried just installing the version of lm-sensors in the 4.x x86 repo and everything installed fine, but I get the same error when trying to run sensors-detect.

There are quite a few directions I could go in - like compiling libiconv for 5.x x86_64, but I thought it would be wise to ask first in case it is something obvious with the move to 5.x x86_64 that I am unaware of.

Thanks for any help, thoughts, and/or points in the right direction,

I don't think it affects the result, but libiconv should not be needed - glibc provides the iconv functions in tc.

Code: [Select]

unable to execute /usr/local/sbin/sensors-detect: No such file or directory
This probably means that sensors-detect is a script looking for perl or python in /usr instead of /usr/local or perhaps for bash - if so, you can edit the script to correct the error.

Ah that makes sense, thanks so much Juanito.

I looked at the sensors-detect script and saw that it is looking for Perl in /usr/bin/ so I tried this as a quick fix and everything works beautifully: sudo ln -s /usr/local/bin/perl /usr/bin/perl

Thanks again for the help!

So even though my first question was answered (thanks again, Juanito) I never got lm-sensors working on Pure64 5.x, but I had to set the project aside for a while.  I have finally gotten back to it for the last week or so but am still stuck.

The easiest way to explain is, this compile process works:

• Boot Core 4.7.7 (x86)
• tce-load -wi compiletc squashfs-tools-4.x perl5 hwmon-3.0.21-tinycore
• cd /home/tc/
• wget -O - http://dl.lm-sensors.org/lm-sensors/releases/lm_sensors-3.3.5.tar.bz2 > /home/tc/lm_sensors-3.3.5.tar.bz2
• tar -xvf lm_sensors-3.3.5.tar.bz2
• cd /home/tc/lm_sensors-3.3.5
• make all
• make DESTDIR=/tmp/lm-sensors install
• mksquashfs /tmp/lm-sensors/ /mnt/sda1/tce/optional/lm-sensors.tcz
• tce-load -i lm-sensors

At that point I can run "sudo sensors-detect" and it both detects the coretemp sensor and finds the coretemp module.

However, this compile process does not work (on the same hardware):

• Boot Pure64 5.2
• tce-load -wi compiletc squashfs-tools perl5 hwmon-3.8.10-tinycore64
• ...the rest of the process in identical...

I have to run sensors-detect like this: sudo /usr/local/bin/perl /usr/local/sbin/sensors-detect
The script finds the coretemp sensor, but gives the following error, indicating that it cannot find the coretemp module:

Code: [Select]

Warning: the required module coretemp is not currently installed on your system.
I am confused by that error because hwmon-3.8.10-tinycore64 has "coretemp.ko.gz" listed just like hwmon-3.0.21-tinycore. (http://ftp.vim.org/os/Linux/distr/tinycorelinux/4.x/x86/tcz/hwmon-3.0.3-tinycore.tcz.list)

Any help is always greatly appreciated.

does "lsmod" show if the coretemp module is loaded?

No sir, here are the modules that are listed after loading all the needed TCZs (compiletc squashfs-tools perl5 hwmon-3.8.10-tinycore64):

Code: [Select]

cpufreq_userspace
cpufreq_stats
cpufreq_powersave
cpufreq_conservative
squashfs
loop
hid_logitech_d j
mperf
microcode
r8169
serio_raw
pcspkr
lpc_ich
xhci_hcd
mfd_core


[Juanito]

Does "sudo modprobe coretemp" load it?

Does "sudo modprobe coretemp" load it?

Nope, I get:

Code: [Select]

modprobe: module coretemp not found in modules.dep

[Juanito]

Boot Pure64 5.2
tce-load -wi compiletc squashfs-tools perl5 hwmon-3.8.10-tinycore64
...the rest of the process in identical...

You should be using hwmon-3.8.13-tinycore64 with corepure64-5.2 - it's maybe better to use "tce-load -i hwmon-KERNEL"

Brilliant!!! I didn't realize that the "-KERNEL" option gave you the most current hwmon for the booted core.

Everything works as expected now, thanks a ton Juanito!

In summary, here is my full working process to get coretemp sensor readings:

• COMPILE AND INSTALL:
• Boot Pure64 5.2
• tce-load -wi compiletc squashfs-tools perl5 hwmon-KERNEL
• cd /home/tc/
• wget -O - http://dl.lm-sensors.org/lm-sensors/releases/lm_sensors-3.3.5.tar.bz2 > /home/tc/lm_sensors-3.3.5.tar.bz2
• tar -xvf lm_sensors-3.3.5.tar.bz2
• cd /home/tc/lm_sensors-3.3.5
• make all
• make DESTDIR=/tmp/lm-sensors install
• mksquashfs /tmp/lm-sensors/ /mnt/sda1/tce/optional/lm-sensors.tcz
• tce-load -i lm-sensors
   
• RUN DETECTION SCRIPT:
• sudo /usr/local/bin/perl /usr/local/sbin/sensors-detect
   
• BOOT PERSISTENCE:
• echo etc/sysconfig/lm_sensors >> /opt/.filetool.lst
• echo /sbin/modprobe coretemp >> /opt/bootlocal.sh
   
• REBOOT WITH BACKUP:
• filetool.sh -b
• sudo reboot

Once I get this project complete I will properly package up all the tczs that I have compiled for 5.x x86_64 and submit them for inclusion in the repo.  I have actually had to compile quite a few that will hopefully be be helpful to other users (ncursesw, nano, lsof, ntpclient, unclutter, xdotool, imake, GraphicsMagick, etc.) but I need to make sure everything is working correctly first.
