Hi Prasad, The running kernel version has to EXACTLY match with the kernel source tree that you are compiling your module against. This includes the EXTRA_VERSION information in the makefile. For e.g, a running "2.6.9-5.EL" (Redhat) kernel won't be able to load a module compiled against 2.6.9. Also, I think (but I'm not sure) that the compiler must be the same that was used in compiling the kernel. Can somebody please confirm this?
Yes, it has to be same.
Thanks, Rajat -----Original Message----- From: kernelnewbies-bounce@xxxxxxxxxxxx [mailto:kernelnewbies-bounce@xxxxxxxxxxxx]On Behalf Of prasad hegde Sent: Thursday, July 05, 2007 7:05 AM To: kernelnewbies Subject: problem with registering net_dev Hi, I am a newbie trying to learn working of network device. I was trying a stripped down version of snull.c example in ldd3 I am not able to load the module. dmesg says net_drive: disagrees about version of symbol alloc_netdev net_drive: Unknown symbol alloc_netdev Even though I am running 2.6.20 and my code is also compiled against 2.6.20, they both are different kernels. Is this a problem, I dont think so. My relevant code snippet is int snull_init_module(void) { int result, i, ret = -ENOMEM; /* Allocate the devices */ snull_devs[0] = alloc_netdev(sizeof(struct snull_priv), "sn%d", snull_init); snull_devs[1] = alloc_netdev(sizeof(struct snull_priv), "sn%d", snull_init); if (snull_devs[0] == NULL || snull_devs[1] == NULL) goto out; out: if (ret) return ret; } void snull_init(struct net_device *dev ) { return; } module_init(snull_init_module); Any help or pointers are appreciated.
