I compile for a non-installed (cross compiled) kernel with:

     NDPI_PATH=/usr/src/nDPI KERNEL_DIR=/usr/src/linux make

If you need MODULES_DIR (not sure why?) then I guess just add that

You can install the kernel module easily enough, either by adding 
"modules_install" to the end of the above (lib location should be picked 
up automatically) or manually with something as simple as:

     mkdir /lib/modules/your_kernel/extra
     cp src/xt_ndpi.ko /lib/modules/your_kernel/extra
     depmod -a

Incidentally, not sure why use that /extra directory?  Anyone got a 
better suggestion on location?

Obviously *also* install the netfilter module (ipt/libxt_ndpi.so) into 
your netfilter modules location

Does that get you going?
