How to add header file

Hey,

I wanted to do some linux kernel modifications to learn it for myself.

I edited file /usr/src/linux/drivers/block/ide.c and added there function call, I also added header myLib.h to ide.c file. It looks like that:

ide.c

Code:

...
#include "myLib.c"
...
doTest1();
...

myLib.h

Code:

void doTest1(void);

myLib.c

Code:

void doTest1()
{
 printk(KERN_INFO "DONE ITS WORKING");
}

myLib.h and myLib.c are both blaced in /usr/src/linux/drivers/block/

While compiling kernel i get some kind of info of missing reference for doTest1() function.

So far I have found that i should modify /usr/src/linux/drivers/block/Makefile Is it right way or something else is wrong ? Is modifying Makefile is right then how to modify it ?

Thanks!

you need to include .h files, therefore #include "myLib.c" is definitely not ok.
