[SOLVED] How to compile linux device driver in Red Hat Linux-2.6.18/Fedora10

sujeet_net29 · 12-03-2010, 09:22 PM

Hi I am sujeet singh, i am doing device driver programming, I wrote a program as:

#include<linux/kernel.h>
#include<linux/module.h>

static int init_module(void)
{
printk(KERN_INFO "Hello world\n");
return 0;
}
static void cleanup_module(void)
{
printk(KERN_INFO "Goodbye world\n");
}

Now:question is how to compile this in fedora10 and RHEL 5.1

Hi

take a look here http://www.linfo.org/create_c1.html. If you are missing compiler try

Code:

yum install gcc

.

hello.c

Code:

#include<linux/kernel.h>
#include<linux/module.h>

int init_module(void)
{
printk(KERN_INFO "Hello world\n");
return 0;
}
void cleanup_module(void)
{
printk(KERN_INFO "Goodbye world\n");
}

Makefile :

Code:

 
obj-m    := hello.o

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

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

The command 'make' will create 'hello.ko'.

yum install gcc

might not work on the EOL fedora 10 if too many of the mirrors have remover that unsupported and dead repo
fedora is currently at fedora 14

for red hat
use the compiler in the RHN
IF THIS is a paid for rhel5
RHEL must have a paid license to install software

Code:

yum groupinstall "Development Tools" "Development Librarys"

will work on RHEL 5 ( with a license)

Thanks for reply

But still I get problem as: module.h is not found/kernel.h is not found

# yum install kernel-devel

Fedora and EL 5 ( + CentOS 5.5 + Scientific SL55 ) :
No errors, using the files shown in post # 3.
'make' is creating hello.ko

Solution : Install or update 'kernel-devel'.
Must be the same version as your kernel.
