MAKE 文件


# Makefile2.6
ifneq ($(KERNELRELEASE),)
#kbuild syntax. dependency relationshsip of files and target modules are listed here.
mymodule-objs := net.o
obj-m := net.o
else
PWD := $(shell pwd)
KVER ?= $(shell uname -r)
KDIR := /lib/modules/$(KVER)/build
all:
$(MAKE) -C $(KDIR) M=$(PWD)
clean:
rm -rf .*.cmd *.o *.mod.c *.ko .tmp_versions
endif



编译结果：
make -C /lib/modules/2.6.22-14-generic/build M=/media/DATA__/test－netfilter/code filter3/test
make[1]: Entering directory `/usr/src/linux-headers-2.6.22-14-generic'
make[1]: *** No rule to make target `filter3/test'. Stop.
make[1]: Leaving directory `/usr/src/linux-headers-2.6.22-14-generic'
make: *** [all] Error 2


什么问题呀？ 怎样解决呀 ？？？？

你可以尝试在makefile文件的这些行之前加入一个tab键：$(MAKE) -C $(KDIR) M=$(PWD)
