'Unkown symbol in module' error while insmodding - but it should be fine!?

[Cormac_Redmond]

Hi,

I have compiled my kernel module, after a lot of debugging.

So heres what I do:

bounce latest1 # insmod nf_lb.ko
insmod: error inserting 'nf_lb.ko': -1 Unknown symbol in module
bounce latest1 #

So then I do a 'dmesg' and get:

nf_lb: Unknown symbol queue_delayed_work
nf_lb: Unknown symbol flush_workqueue
nf_lb: Unknown symbol destroy_workqueue
nf_lb: Unknown symbol __create_workqueue

These are functions used by the workqueue(linux/workqueue.h) I am using, and are standard in 2.6 and probably older kernels? Plus it compiled fine, so why am I getting this?

Also, I did a:

cat /proc/kallsyms | grep 'work'

and see that these symbols ARE in the kernel.

Any ideas? Any help much appreciated!


Thanks,

Cormac Redmond

Ah....

I had to change

MODULE_LICENSE("$LICENSE$");

to

MODULE_LICENSE("GPL");

Feck sake!
