Hi,
I tried today to link a lib (.a) to my kernel module but I could not
found howto do it.
I prepared a little example:
hello.c:
#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/io.h>
#include <linux/version.h>
#include "hello_lib.h"
MODULE_LICENSE("GPL");
int init_module(void)
{
printHello();
return 0;
}
void cleanup_module(void)
{
printk("remove module\n");
return;
}
hello_lib.c:
int helloWorld(void)
{
printk("Hello World\n");
return 0;
}
hello_lib.h:
int helloWorld(void);
Makefile:
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
EXTRA_CFLAGS+=-I/usr/home/idefix/programming/kernel_hello_world_lib/
obj-m := hello.o
hello-obj := hello.o libarinc653.a
all:
gcc -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
Can please someone help me here?
Thx a lot,
Matthias
