You need to install the kernel headers, then run "make scripts" in the headers directory: root@beaglebone:/# apt-get install linux-headers-`uname -r` root@beaglebone:/# cd /lib/modules/`uname -r`/build root@beaglebone:/# make scripts Once competed, your make of the out of source kernel module should get past that initial error. frank -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
