I am interested in building only mychar.ko and no the whole kernel.
I am doing my development on Ubuntu 7.10 with kernel version 2.6.22-14-generic
Although this Makefile works and I could able to generate "mychar.ko". Also when I do "insmod mychar.ko" the module installs successfully, and I could see "mychar" in "lsmod" output.
(But could not find it in - /proc/devices)
I have added some printk in my module_init function but after doing insmod I am not able to see any output in /var/log/messages
If I put everything in single C file(only mychar.c), I could able to see all the output in /var/log/messages.
Please let me know what am I doing wrong while including the 2 C files and how should the makefile be modified.
( I have referred Documentation/kbuild makefiles.txt for creating my makefile)
