Dear Team, in fact, I did not make -f Makefile.p4b but only make in the root of your package. But if I change to proc/hotplug, where the Makefile.p4b resides and execute, I get the following Errors: LX1:/home/supervisor/linux_packete/lm_sensors-2.7.0/lm_sensors-2.7.0/pro g/hotplug # make -f Makefile.p4b grep: /lib/modules/2.4.19-4GB/build/Makefile: No such file or directory grep: /lib/modules/2.4.19-4GB/build/include/linux/autoconf.h: No such file or directory cc -D__KERNEL__ -DMODULE -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -I/lib/modules/2.4.19-4GB/build/include -c -o p4b_smbus.o p4b_smbus.c p4b_smbus.c:60:2: #error ERROR - You must have 'Support for hot-pluggable devices' enabled in your kernel (under 'general setup')!!
