I found Jesse Goerz/Kevin McKinley’s ‘Creating Custom Kernels with Debian’s Kernel-Package System’ a great help. So far the only thing I’ve needed to do was replace gcc with egcs64. The rest of the instructions worked like a charm. (I hit a small arlan.o error but removing the offending module/driver from menuconfig fixed it.)
My brick wall/challenge this time is vfc_dev.c errors (Driver for the Videopix Frame Grabber) but I cannot find the offending driver in menuconfig to remove it.
Can someone give me a helping hand?
