    SubjectRe: Link lib to a kernel module
    Hello Dipti,

    * Dipti Ranjan Tarai <dipti@innomedia.soft.net> [25-10-06 11:16]:

    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
