Showing that debugging a LKM which does not compile is impossible is left as an exercise to the reader :-) Seriously, LKMs have strict dependencies on kernel releases... some modules can span multiple releases, but most ones need some explicit support. A module for 2.4 kernels will probably work with any recent 2.4 kernel, while for 2.6 dependencies are much stricter thanks to the extremely active development happening. > I have got the executable linux and when I try to > launch it via following command > $linux > The following error comes.
