合併多個檔案成一個模組

有時候檔案會分散，如果想合在同一個模組的話可以用以下方式 start.c:

/*
 *  start.c − Illustration of multi filed modules
 */
#include <linux/kernel.h>       /* We're doing kernel work */
#include <linux/module.h>       /* Specifically, a module */
int init_module(void)
{
        printk(KERN_INFO "Hello, world − this is the kernel speaking\n");
        return 0;
}

stop.c:

 /*
 *  stop.c − Illustration of multi filed modules
 */
#include <linux/kernel.h>       /* We're doing kernel work */
#include <linux/module.h>       /* Specifically, a module  */
void cleanup_module()
{
        printk(KERN_INFO "Short is the life of a kernel module\n");
}

MakeFile寫法:

obj−m += startstop.o
startstop−objs := start.o stop.o
all:
        make −C /lib/modules/$(shell uname −r)/build M=$(PWD) modules
clean:
        make −C /lib/modules/$(shell uname −r)/build M=$(PWD) clean
