Re: Re: [Ltib] how to build a kernel module using ltib? (docu)

[Stuart Hughes]

Hi Vincent,

This seems to be a common problem, someone else was asking today.  I'll
see if I can find an example and post it.  I need to ask some other
people how to do this as I don't work on the kernel (regularly).

Regards, Stuart
