| Code: | root@tower kevin # sensors-detect
No i2c device files found. Use prog/mkdev/mkdev.sh to create them.

And do you use 2.4.x kernel ? Because in 2.6.x you haven't to run sensors-detect. You only need to have kernel modules for i2c.

And did you

?
I think that you should write a little bit more about your problem.

Sorry about that, okay, this is what I'm doing, I'm following this setup to get my sensors to work on my systems and getting the problem I'm posting about at this point in the setup.
Point I'm at in the setup
| Quote: | if you're running kde you can use ksensors instead of gkrellm.
| Code: | Code:
# emerge ksensors |
Then run:
| Code: | Code:
# sensors-detect |
|
This is what I'm getting back:
| Code: | root@tower kevin # prog/mkdev/mkdev.sh
bash: prog/mkdev/mkdev.sh: No such file or directory
root@tower kevin #

Is this file really missing ?
try
| Code: |
find /* -name "mkdev.sh" |
I have lm-sensors 2.8.5 and when I emerged it this text appeared :
| Quote: | echo
einfo "*****************************************************************"
einfo
einfo "This ebuild assumes your /usr/src/linux kernel is the one you"
einfo "used to build i2c-2.8.2."
einfo
einfo "For 2.5+ series kernels, use the support already in the kernel"
einfo "under 'Character devices' -> 'I2C support' and then merge this"
einfo "ebuild."
einfo
einfo "To cross-compile, 'export LINUX=\"/lib/modules/<version>/build\"'"
einfo "or symlink /usr/src/linux to another kernel."
einfo
einfo "*****************************************************************"
echo
|
and
| Quote: | einfo
einfo "The lm_sensors hardware sensors package has been installed."
einfo
einfo "It is recommended that you read the lm_sensors documentation."
einfo "To enable lm_sensors you will need to compile i2c support in"
einfo "your kernel as a module and run /usr/sbin/sensors-detect to"
einfo "detect the hardware in your system."
einfo
einfo "Be warned, the probing of hardware in your system performed by"
einfo "sensors-detect could freeze your system. Also do not use"
einfo "lm_sensors on certain laptop models from IBM. See the lm_sensors"
einfo "documentation and website for more information."
einfo
einfo "IMPORTANT: When you merge this package it installs kernel modules"
einfo "that can only be used with the specific kernel version whose"
einfo "source is located in /usr/src/linux. If you upgrade to a new"
einfo "kernel, you will need to remerge the lm_sensors package to build" einfo "new kernel modules."
einfo
echo
|
look to ebuild of your version for more information.
You can also look to the i2c ebulid.

Emerging lm-sensors isn't enough. I went and manually downloaded the lm-sensors package. Extract it and you will find the mkdev.sh file in there. To save you some time this is the entire contents of that script from the 2.8.6 version.
| Code: |
#!/bin/bash
# Here you can set several defaults.
# The number of devices to create (max: 256)
NUMBER=32
# The owner and group of the devices
OUSER=root
OGROUP=root
# The mode of the devices
MODE=600
i=0;
while [ $i -lt $NUMBER ] ; do
echo /dev/i2c-$i
mknod -m 000 /dev/i2c-$i c 89 $i
chown "$OUSER:$OGROUP" /dev/i2c-$i
chmod $MODE /dev/i2c-$i
i=$[$i + 1]
done
|
Save it to a script file and run it as root... |

thanks a lot Drunkula, your script save my day.
iv'e got this problem not in my gentoo box, but in a debian box that i'm installing.
the funny thing is the only place where i found my solution is here.
Debian is a great distro, but their docs sucks and their community is a bit selfish.
GENTOO FORUMS RULEZZZZ! |

In that case, what do you have to do to get rid of the "No sensors found!" response?
I've got another problem, that may or may not be related. This is on an IBM Intellistation. The sensors-detect command has blacklisted all IBM systems because of Thinkpad problems. But this isn't a Thinkpad, and I don't see any override switch.
