[LITMUS^RT] CreateAPluginTutorial - Step4 : error when compiling

[Schorr Stefan]

Hi all,

I'm trying to follow the Create A Plugin Tutorial from the webpage.
The first steps work like a charm, step 4 however doesn't compile :(

I copied the code from the website and I created a new local git
branch, so I'm absolutely sure that the only file I changed - apart
from the Makefile - is sched_demo.c (so I don't understand why
the error messages below point to .h files).

Please give me some hint what goes wrong here...

Best Regards
Stefan


Here's the error I get, when doing make bzImage
