二 Makefile文件有两种写法:
一种是:
# Add your debugging flag (or not) to CFLAGS
ifneq ($(KERNELRELEASE),)
obj-m := boot.o
else
KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif
另外一种是:
# Add your debugging flag (or not) to CFLAGS
ifneq ($(KERNELRELEASE),)
obj-m := boot.o
else
KERNELDIR ?= /usr/src/linux-headers-2.6.38-8-generic
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif
比较两者可以发现,该两个Makefi二 Makefile文件有两种写法:

比较两者可以发现,该两个Makefile的唯一差别是KERNELDIR的不同
