Hello,

I'm trying to follow a tutorial on how to write a driver in Linux (a Hello World driver) however I get errors when I'm compiling it.

Under the /usr/src/ folder I have 2 folders:

Both of them say linux-headers-2.6.... but one of them says 'generic' at the end.

I guess that's the Kernel Source. However when I compile the driver errors come up saying that the can't open the <linux/module.h> and <linux/init.h> files.

How can I fix this issue? I've read some other websites saying that I should have a 'linux' folder under /usr/src, however I don't... could that be the problem???

What distro are you running?

Ubuntu 9.04

You need the source for the kernel you're running. Open Synaptic to look for it and install it. Look for module-init tools (think that's the name) as well.

I'm sorry, I figured it out.. I did have the Kernel Source installed.. the stupid mistake was that my driver source files were in a Folder that had a space in the name (Linux Docs/Drivers) something like that.. So when I typed the 'make' command it didn't work.
Stupid mistake, but now everything is OK.. thank you!!!

Glad you've got it sorted out.
