Hello! With i2c-2.8.0 and lm_sensors-2.8.0 there is a conflict on the <linux/i2c-dev.h> header. i2c (when compiled using the option 3 - patched into the kernel) installs its i2c-dev.h into the kernel includes; lm_sensors installs its i2c-dev.h into /usr/include/linux - which may be the same, depending on the symlinks configuration. I see that i2c-dev.h in the i2c package was cleaned and contains no userspace parts, and i2c-dev.h from the lm_sensors package is the userspace header. Maybe this userspace header should be installed in some other place - e.g., into $(LIBINCLUDEDIR)? -- Sergey Vlasov
