Module compilation needs kernel header files or kernel sources?

i linked my build folder to /usr/src/linux-2.6.35-headerfiles instead of kernel source file.

Code:

still i able compile the modules...
Although i have question that,
should i link to kernel header folder? or kernel source directory?

In general, header files are sufficient for compiling kernel modules. The entire kernel source is needed if you want to compile a custom kernel.

thank you so much brother.i love you.because its indeed important knowledge for me.
by the way...
did you see the source folder in the listing of files? i linked to the actual source folder.
will it be useful in future or any application would access it?
