Re: Link lib to a kernel module

Hello Dipti,

* Dipti Ranjan Tarai <dipti@xxxxxxxxxxxxxxxxxx> [25-10-06 11:16]:
Now in mod2 call test_export() of mod1, compile it and load the module u
can able to access test_export().

thx for that hint, but I want one module :)

I was now successfull with the following code:
hello_lib.h:
int printHello(int);

hello_lib.c
int printHello(int count)
{
int i;

for(i=0;i<=count;i++)
{
printk("Hello World\n");
}

return 0;
}

hello.c:
#include <linux/kernel.h>
#include <linux/module.h>
#include "hello_lib.h"

MODULE_LICENSE("GPL");

int init_module(void)
{
printk("call function\n");
printHello(5);
return 0;
}

void cleanup_module(void)
{
printk(KERN_INFO "remove module\n");
return;
}

Makefile:
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

obj-m += test.o
test-y := hello.o libhello_lib.a

all:
gcc -I/usr/include -c -o hello_lib.o hello_lib.c
rm -f libhello_lib.a
ar cru libhello_lib.a hello_lib.o
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules KBUILD_VERBOSE=1


Best regards,
Matthias
