Re: [coLinux-users] kernel module programming

[yin s. <sun...@gm...>]

are you able to build the colinux kernel and its modules? (./configure; make)
I think this is the way to verify your build environment is properly setup.
then you can try to modify one of the modules, for example comouse.c
after these practice, you should be able to figure what is wrong for
your own module.
