Please use a Linux system to build the Linux kernel on for your first attempt. Trying to get it to build on a non-Linux system is not always a trivial exercise as you are finding out. And again, the problem is in your filesystem type you are building on, it is case-insensitive. Fixing that is the problem here, it is not a Linux kernel specific thing. good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
