Replacing "-custom" in my New Kernel development configuration

Replacing "-custom" in my New Kernel development configuration

[s.rawat]

Hello,
I recently built the 3.18.5 kernel according to instruction on the
linuxkernel newbie page .I used /sbin/installkernel script to install the
modules and updated the grub.cnf.
On a reboot i get option 3.18.5[b]-custom[/b] and booted in.But now since I
am modifying the kernel and needed headers in /user/src for the same kernel
name i am using i.e 3.18.5 , but uname-r gives 3.18.5[b]-custom[/b].I can
still install headers with the name 3.18.5 and rename it to
3.18.5-custombut how is there any other way out to fix this.If I could
replace "-custom" in all the places or do I have to do it manually - in
grub, all all other places?I dont know how many places it has been
reference as "-custom".
I might have taken a wrong route i guess :S ! Have I??
Rgds,S

Take a look at CONFIG_LOCALVERSION option.

Your headers for ?-custom? kernel will be under the folder where you have downloaded 3.18.5 kernel.

Yes the headers are there in the sources of 3.18.5 kernel.But then I have
to change all the references to linux/<header_files.h> in my modules to the
path of <kernel_source>/include/linux/<header_files.h>.This could be
corrective action.I am looking for preventive action .
CONFIG_LOCALVERSION appends whatever name we want to append after the
kernel version.
I was looking for downloading the kernel headers for the custom kernel I
built whose name has been changed to 3.18.5-custom.
uname -r give => 3.18.5-custom. :( (cant use it sudo apt-get install
linux-header-$(uname-r) :(

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.

And _please_ don't top post in your answer. That makes it even harder to
determine what it is you actually want to do.

>> 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.

That is: in the way I called "certainly the wrong thing to do"?

I guess section "6.3 Symbols From Another External Module" from
Documentation/kbuild/modules.txt contains possible solutions to that
problem.

To get good answers it helps to quote the command you used and the
output (stderr and stdout) that this command generated.

Greg K-H wrote a booklet that explains most of the problems you've run
into in, I think, great detail: "Linux Kernel in a Nutshell". Perhaps it
is available for free on the interwebs (as its license allows that).

Anyhow, I'm running out of time here. I'll be glad to try to talk you
through setting up things properly (especially /usr/src/[...]
or /lib/modules/[...]/build), if still needed, next Monday.

Hope this helps,

You have to Modify your Makefile (-C) to point to your source.

make -C $(kennel source) SUBDIRS=$(Your source code folder) modules
