Re: Problems using the comedi_config command

Looks to me that the linux src tree and the kernel you are using are not 
the same. Happened to me when I was trying to build another project, 
namely HOSTAP.

A good way to solve this is to roll a complete kernel and build that, and 
then using it install comedi. This gauranteed that your linux src tree is 
in full working order.

The other way is well described in the docs.

for example I can tell you that the module you have build was built in a 
source tree configured for a multiprocessor Pentium 4 with preemption, 
while the kernel currently running is a multiprocessor pentium or better.

Something in your kernel build tree is wrong.
