With the Makefile I provided, you have to execute "make", instead of
"make hello-1". Also make sure you have installed the RPM
kernel-source. The command:
rpm -qa | grep kernel-source
Please refer to a good guide on writing Makefiles, and the latest
guide of Linux Kernel Module Programming guide for more details.
