Since your makefile has no all target, it thinks that there is nothing to be done. Your makefile needs some more stuff in it. What the kernel build system wants to see is just the obj-m += mydriver.o line. So you need to use some make conditionals: ifneq ($(KERNELRELEASE),) obj-m += mydriver.o else all : modules modules : make -C ..kerndev/linux-2.6/ M=$(PWD) modules clean : make -C ../kerndev/linux-2.6/ M=$(PWD) clean endif -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
