What is wrong With make?

C

#include <linux/module.h>
#include <linux/kernel.h>
int init_module(void)
{
    printk(KERN_INFO "Hello world 1.\n");
    return 0;
}
void cleanup_module(void)
{
    printk(KE开发者_如何转开发RN_INFO "Goodbye world 1.\n");
}

Guesswork: You did not set the M environment variable in your custom Makefile. See http://tldp.org/LDP/lkmpg/2.6/html/x181.html

And the next time, please do indeed ask a more specific question than 'What is wrong?'

I dispute that anything is wrong with make. I am very certain, though, that something is wrong with your Makefile. According to some random internet searching, try something like this:

make -C /lib/modules/2.6.32-5-686/build SUBDIRS=/home/mgh/Documents modules

This is assuming that your Makefile resides in /home/mgh/Documents.
