After searching the internet I found a description for Raspi.
Here is the file > dl.lm-sensors.org/i2c-tools/releases/i2c-tools-3.1.0.tar.bz2
download and tar -xjf i2c-tools-3.1.0.tar.bz2
cd i2c-tools-3.1.0.tar.bz2
edit file setup.py and after url= ..lm-sensors.. insert:
include_dirs=["../include, "/usr/include"],
finally: python setup.py install
and all was working in Slackware (must try with SZ)
this is opensource and inside are more modules like eeprom
very nice
maybe this could be installed in next release by default
