Hi, finally I found the answer to my question at http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1344 . I switched module compilation of, since I already compiled them with the kernel. Your Makefile is not creating sensors.h, since it is not included in the SRCDIRS variable. After switching on kernel module compilation, the header file is created. This solution is not really nice, since it would overwrite the already created modules. kind regards, Rainer
