Changing those preprocessor include lines is certainly the wrong thing
to do.

What exactly are you trying to achieve? Looking at your original
question it seems this is about the headers in /usr/src/kernels/$(uname
-r). (That is the location used in Fedora.)
But why do you need those headers? See, these headers in that directory
are for building external modules. Ie, modules not already installed
in /lib/modules/$(uname -r). But that would be easier to do from within
the directory in your home directory where you downloaded the kernel's
source code.
>> Yes I am building the external modules .The headers(linux/<header_files>) I have included the way I have said above. The reason i asked this is becuase my driver modules compiles without any error except it gave warning that certain symbols (function_names_) are undefined in the .ko driver module .These function_names_symbols are declared in the header files I included in my driver code like i said above..
I compiled did like this :
make -C <path to kernel sources (compiled kernel - does it matter compile or not compiled?)> SUBDIRS=<path to my driver code placed in my home directory (not inside the kernel sources) modules
> Compiled successfully except the warnings I stated above.That is the reason i asked to way to install the headers of my compiled kernel.
And _please_ don't top post in your answer. That makes it even harder to
determine what it is you actually want to do.
