Well, i2cdetect, i2cdump and i2cset can be compiled when running a 2.6 kernel - so lots of people actually do. > (i) use lm_sensors i2c-dev.h instead of kernel header file > #include <linux/i2c.h> > #include "i2c-dev.h" /* lm_sensors header file */ > > causes compile errors due to <linux/i2c.h> Do not include linux/i2c.h in a user-space program. This is a kernel-space header file. If should work just fine without it, the only header file you really need is i2c-dev.h. -- Jean Delvare
