编写makefile以后 make不通过

lantian0811

我的makefile是这么写的：
内核的源码在/home/juer/src/linux-2.6.25.16里面
PWD=$(shell pwd)
KERNEL_SRC=/home/juer/src/linux-2.6.25.16
obj-m :=ip46natForTest.o
module-objs :=ip46natForTest.o
all:
        $(MAKE) -C $(KERNEL_SRC) M=$(PWD) modules
clean:
        rm *.ko
        rm *.o



报错：

root@juer:/home/juer/ip46natForTest# make
make: Warning: File `Makefile' has modification time 5.3e+04 s in the future
make -C /lib/modules/2.6.25.16juer/build M=/home/juer/ip46natForTest modules

希望高手来指点下

PCliangtao

obj-m :=ip46natForTest.o
module-objs :=ip46natForTest.o

修改为
obj-m :=ip46natForTest.o
ip46natForTest-objs :=ip46natForTest.o

如果模块的依赖目标文件只有一个... 第二句话完全可以不要...

你的内核源码是编译过的吗？

    需要是编译过的吗？貌似我的没编译过的也可以

如果你只有一个.c 文件，则把这一句去掉：
module-objs :=ip46natForTest.o

如果你有两个以上的文件(假设分别是 a.c, b.c)，则需要：
obj-m :=ip46natForTest.o
ip46natForTest-objs := a.o b.o
