Проблема компиляции модуля под Linux

[Zlodei]

Я первый раз с этим сталкиваюсь. Просто возникла необходимость написания драйвера для диплома.

Когда я пробую собрать модулю по примерам то че то у меня не получается!

Пожайлуста направте на путь истинный.

___________________________

Файл mydrv.c

#include <linux/module.h>

#include <linux/init.h>

MODULE_LICENSE("GPL");

static int __init my_init(void)

{

printk("<1>Da\n");

return 0;

};

static void __exit my_cleanup(void)

{

printk("<1>Net\n");

return;

};

module_init(my_init);

module_exit(my_cleanup);

Файл makefile

obj-m += mydrv.c

Команда для компиляции:

make -C /lib/modules/`uname -r` SUBDIRS=$PWD makefile

После чего не выдается ни каких ошибок и сообщений вообще. И получается какбудто команда выполнена. Хотя объектного файла mydrv.o я не нахожу ни где.

makefile и mydrv.c расположены в одной папке /home/Nikolai. Компилирую тоже из этой папки.

ОС ASP Linux 2.6.9-1.667

________________________

Немного сдвинулось. Изменил makefile на:

obj-m := mydrv.c

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

PWD := $#(shell pwd)

default:

$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

Командная строка (из директории с makefile):

make -f makefile

Теперь выдает следующее:

[root@localhost Nikolai]# make -f makefile

make -C /lib/modules/2.6.9-1.667asp/build SUBDIRS= modules

make[1]: Entering directory `/lib/modules/2.6.9-1.667asp/build'

В чем проблема?

Имхо - в ядре. Попробуйте другое (лучше всего торвальдовское с kernel.org)

[Zlodei]

После компиляции модуля образовался файл mydrv.ko

Но при его инсталяции появляется ошибка:

[root@localhost Nikolai]# insmod ./mydrv.ko

insmod: error inserting './mydrv.ko': -1 Invalid module format

Что это значит?

В принципе, tainted не должно мешать загрузке модуля... буду думать
