Unhappy bug me out


I m a rookie in linux fc7..trying to compile a c code for building a dummy network device driver. . but whenever I try to compile the code , I get a long list of errors. firstly it says that header files not found...someone suggested to install glibc-devel package for inclusion of header files in gcc...I did download the package but it failed to install as it required dependencies...now I m in dire need of help from experts in two areas

1. tell me what dependencies shud I search for the glibc package installation and which folder I shud install it! with complete txt commands.

2. does anyone know ho to build a dummy driver for rtl8139 in linux?

btw I m running fc7...on a 32 bit intel processors......


this was the code I was trying to compile

http://linuxgazette.net/issue93/bhaskaran.html

#define MODULE
#define __KERNEL__

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

#include < linux/netdevice.h >

int rtl8139_open (struct net_device *dev)
{
printk("rtl8139_open called\n");
netif_start_queue (dev);
return 0;
}

int rtl8139_release (struct net_device *dev)
{
printk ("rtl8139_release called\n");
netif_stop_queue(dev);
return 0;
}

static int rtl8139_xmit (struct sk_buff *skb,
struct net_device *dev)
{
printk ("dummy xmit function called....\n");
dev_kfree_skb(skb);
return 0;
}

int rtl8139_init (struct net_device *dev)
{
dev->open = rtl8139_open;
dev->stop = rtl8139_release;
dev->hard_start_xmit = rtl8139_xmit;
printk ("8139 device initialized\n");
return 0;
}

struct net_device rtl8139 = {init: rtl8139_init};

int rtl8139_init_module (void)
{
int result;

strcpy (rtl8139.name, "rtl8139");
if ((result = register_netdev (&rtl8139))) {
printk ("rtl8139: Error %d initializing card rtl8139 card",result);
return result;
}
return 0;
}

void rtl8139_cleanup (void)
{
printk ("<0> Cleaning Up the Module\n");
unregister_netdev (&rtl8139);
return;
}

module_init (rtl8139_init_module);
module_exit (rtl8139_cleanup);

In order to compile a device driver you need the kernel headers, that match your kernel version. Run:
Code:
uname -r
to find your kernel version and then install the kernel source package.
You can use yum to install packages, as it can find and resolve dependencies.

If you have the installation CDs you can use rpm to install it. Else you can d/l it from here (make sure you get the correct kernel-devel that matches your installed kernel version) and use again rpm to install.
You can also use yum to d/l and install:
Code:
yum install kernel-devel
