Hi everybody, I currently started learning how to write Linux drivers.I am following Linux Device Drivers Third Edition. I have everything set right but the makefile provided seem not to work.I am familiar with makefiles but the kernel build system confuses me Here is the makefile:
# If KERNELRELEASE is defined, we've been invoked from the # kernel build system and can use its language. ifneq ($(KERNELRELEASE),) obj-m := hello.o # Otherwise we were called directly from the command # line; invoke the kernel build system. else KERNELDIR ?= /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules endif It give the following output when I run make : make: Nothing to be done for `default'.
