Problem in loading Module

Problem in loading Module

[Dinesh Ahuja]

I have recently purchased book "Linux Device Drivers"
By Alessandro Rubini. I am very keen to learn the
Kernel Programming and this is my step towards Kernel
Programming.

I request you to all to guide me whenever I get stuyck
up in my learning process. 

I was facing problem in loading a module example
hello.o in my Red Hat Linux Kernel 2.4.20-6.

It gives me an error that module has been compiled for
Kernel 2.4.20 and you are trying to run it on Kernel
2.4.20-6 [which is a kernel comes with Red Hat 9.0]

Please guide me over this issue so that I can proceed
further in learning process.

Thanks & Regards
Dinesh

What kernel headers are you compiling the module against? They must match 
the actual kernel you are using. If you are using Red Hat kernel 2.4.20-6 
then you must compile against Red Hat 2.4.20-6 kernel headers.

you could also try turning off 'module versioning' in which case you
can 'force' load
a module. of course you risk your system when you do this.

I have downloaded the kernel source for 2.4.20-6 and
able to proceed and compile and load kernel.

Thanks a lot for your guidance.
