i have wriiten a makefile which compliles two different modules and create one main object file.
1> if i do make i should get hello1.ko,hello2.ko and combine.ko
2> then i can insmod combine.ko instead of doing insmod hello1.ko and insmod hello2.ko................
hello1.c
----------------------------------------------------------------------------------------------
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/init.h>
static int __init hello_test1_init(void)
{
printk(KERN_INFO "I am in init hello1 \n");
return 0;
}
static void __exit hello_test1_exit(void)
{
printk(KERN_INFO "I am in cleanup hello1 \n");
}
module_init(hello_test1_init);
module_exit(hello_test1_exit);
-----------------------------------------------------------------------------------------------------------------
hello2.c
-----------------------------------------------------------------------------------------------------------------
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/init.h>
static int __init hello_test2_init(void)
{
printk(KERN_INFO "I am in init hello2 \n");
return 0;
}
static void __exit hello_test2_exit(void)
{
printk(KERN_INFO "I am in cleanup hello2 \n");
}
module_init(hello_test2_init);
module_exit(hello_test2_exit);
------------------------------------------------------------------------------------------------------------------
Makefile is
---------------------------------------------------------------------------------------------------------------
obj-m :=combine.o
module-objs :=hello1.o hello2.o
obj-m :=hello1.o hello2.o
all:
make -C /lib/modules/$(shell uname -r)/build SUBDIRS=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build SUBDIRS=$(PWD) clean
--------------------------------------------------------------------------------------------------------------
i dont get error,i will get output hello1.ko and hello.ko but not combine.ko
