Debian Programming :: Compiling Linux Kernel Module

Aug 27, 2014

I'm trying to compile a Linux kernel module called hello-2.c using the command "make -C /lib/modules/$(uname -r)/build M=${PWD} modules" (without the quotes) (which I found online), and the following is the (seemingly successful) output.:

Code: Select allmake: Entering directory `/usr/src/linux-headers-3.2.0-4-amd64'
  Building modules, stage 2.
  MODPOST 0 modules
make: Leaving directory `/usr/src/linux-headers-3.2.0-4-amd64'

However, I don't see a hello-2.ko (in the same folder or anywhere else for that matter). I'm Using Debian GNU/Linux 7.6.

Everything I am doing is within a folder/directory called "thefolder" (without the quotes) in the "/tmp" directory (without the quotes).

Why I can't see a hello-2.ko, and what to do to get it?

Programming :: Compiling Kernel Module Using (/asm/system.h)

Apr 3, 2011

I`m trying to compile sources of kernel module which has been written for kernel 2.6.9. There were many changes in kernel headers since then in current kernel sources. I`ve found that old /asm/system.h was moved under architecture dedicated directory /arch/*/include/asm/system.h. Anyway during sources compilation I`m having errors related to kernel sources. It looks like there is something wrong with this /asm/system.h

Code:

../asm/system.h: In function �__cmpxchg�:
../asm/system.h:248: error: expected string literal before �LOCK_PREFIX�
../asm/system.h:254: error: expected string literal before �LOCK_PREFIX�

Debian :: Compiling XIllybus Kernel Module

Sep 25, 2015

I'm having problems to compile XIllybus kernel module. As this guide explains, [URL] ..... (on the top of page 8 of 25) I unpackaged the tar.gz file and compiled the kernel module by typing the make command in the proper path. When I compile the module with make command, I get the following error:

make -C /lib/modules/3.16.0-0.bpo.4-amd64/build SUBDIRS=/home/xillybus/module modules
make: *** /lib/modules/3.16.0-0.bpo.4-amd64/build: No such file or directory. Stop.
make: *** [default] Error 2

/lib/modules/3.16.0-0.bpo.4-amd64/build path does not exist. What does it mean? Should I have to install some kernel packet? www does not work for me.

Ubuntu :: DKMS Not Compiling New Module Using New Kernel?

Mar 19, 2011

I'm trying to set it up so that I don't have to recompile the driver for my RAID card manually every time there is a kernel upgrade.I found a thread on it, here and a help page here, and it looks like it builds the module fine, but for some reason it's not being inserted into the new kernel, or something. It's like the new kernel doesn't know it exists, even tho modprobe -l shows the newly built module exists (and is in the correct place)Here's the script that I wrote up to get the drivers set up in DKMS:

Code:
#!/bin/bash
set -e

Debian Programming :: Building Kernel Module

Dec 8, 2013

I'm trying to build the kernel module for dvbhdhomerun. The problem is the linux kernel headers provided by Debian do not have the dvb header files. Trying to set up my own kernel source tree to use is not working out so well.

I'm following the instructions in the Debian section here: [URL] ....

My first try compiled, but the modules ender up under /lib/modules/3.2.51/extra instead of /lib/modules/3.2.0-4-amd64/extra. Why?

I tried to start over, but noticed this while running apt-get source linux-image-3.2.0-4-amd64:

Code: Select allReading package lists... Done
Building dependency tree       
Reading state information... Done
Picking 'linux' as source package instead of 'linux-image-3.2.0-4-amd64'
NOTICE: 'linux' packaging is maintained in the 'Svn' version control system at:
svn://svn.debian.org/svn/kernel/dists/trunk/linux/

[Code] ....

The failure to verify the signature has me concerned, but beyond that, what do I do about the different version number when compiling and installing the kernel modules?

Ubuntu :: Compiling Individual Kernel Module From Qcserial.c?

Jan 4, 2011

I am trying to figure out how to compile qcserial.c kernel module from the latest kernel source file located in the 2.6.37-rc8 kernel tree. I have installed the sources for my current kernel 2.6.35-24-generic on maverick and it seems that my includes are not in the right place to make the qcserial.c file happy.

I overcame this issue by passing the -I option to gcc that points to the directories that it is looking for. I am currently getting errors while compiling and I was wondering if it is impossible to compile qcserial.c on my current kernel? I am looking to get the diagnostic port and GPS port enabled for my built-in 3G card.

I havent built modules for quite some time and that was on opensuse with the fglrx module.

Fedora :: Use Rpmbuild To Compile Kernel Without Re-compiling Unchanged Module?

Apr 20, 2011

Using the rpmbuild to compile the kernel, every time the patches will be applied to the source code. So even if no changes are made to the source code and no patches are added to kernel.spec, the whole kernel will still be recompiled, wasting a lot of time

Programming :: Modifying The Elevator.c Module In Kernel?

Feb 22, 2011

There is a file called elevator.c. It is written as a module (i.e it has specific init and exit functions). However we are not able to see it in lsmod listing. We are working on a project where we need to modify this file. Compiling every time we change something will be time consuming. Is it possible to compile just this file and insert it as a normal module?

Programming :: Writing To Console From Kernel Module

Mar 2, 2011

I'm currently doing a tutorial for writing kernel modules. Right now I'm still at the very beginning, i.e. writing my helloworld stuff.

But what I like to do now is to write stuff onto the console, and I don't get it. According to my tutorials I can print stuff on the console using the printk()-function as long as the priority-level of the macro used in printk() is lower than the console_loglevel (how can I find that value out btw?).

But it doesn't work for me. Even if I use KERN_EMERG it still gets only logged, but not printed on the console and I thought KERN_EMERG get always printed...

Here's my code:

Code:

Code:

Everything works fine. But as soon as there are any blanks in mystring, e.g.

Code:

I always get

Code:

Why do I get this error and how can I insert string with blanks?

Debian :: Compiling A X86 Kernel From Amd64?

May 23, 2010

I tried to compile an x86 linux kernel from amd64 machine. It is giving errors even after installing "gcc-multilib" But I wonder, it should be simply doable becuase "gcc -m32" creates 32 bit binary . I would prefer to compile it natively on x86_64 rather than creating an exclusive x86 chroot for that. Has anyone tried this on native x86_64?

I been trying all day to compile a kernel i downloaded from http://www.kernel.org/ (2.6.32.8 )Following this help thread viewtopic.php?t=4468.When i invoke make xconfig i'm just kinda lost at that point. Not really sure what to do, so i just save it as is and then compile/install.when i try to boot the kernel, a kernel panic happens saying it can't not mount the root partition.So i am sure i am missing a step with the xconfig part but not sure what.

Programming :: Adding External Module To Kernel Source?

Apr 27, 2010

There is a module A which is compiled with the kernel. I wrote an external module B which exported a symbol using EXPORT_SYMBOL.The module A now needs to talk with that exported symbol (function call). For that i modified A so that it includes the function call from B. However i now get unidentified symbol errors during 'make' operation as symbols of B are not present during kernel compile and A now kind of depends on B.

One solution is that make B part of the kernel as well. However, it would mean that whenever now i try to compile a kernel with a different source, i have to modify the config files and everything to accommodate B.Hence i am seeking a solution which does not include modifying the kernel.

Programming :: Build Module Against Headers That Are Not From Running Kernel?

Apr 13, 2011

I'm trying to debug a module I programmed but I don't want to do it on the running host but against UML (don't want to reboot every 5 minutes).

The UML kernel I downloaded is 2.6.38.2. I have already downloaded the ubuntu kernel headers for this version (they belong to natty though I'm running maverick.... when I installed the .deb file with dpkg I had no problem at all).

Now I'd like to build said module against these headers. How can I do it?

Here's the makefile for my module code...

this is my x-th attempt to compile the kernel on debian lenny. after solving the damn LGUEST issue, now i got an --append-to-version=-foobar issue?! damn... much time wasted, again. after make menuconfig and make-kpkg clean i start compiling with

error log:
Code:

EDIT: since this is debian specific and i used make -j5 etc. for # of jobs in other distros, is there an option on make-kpkg for that? && any chance for resuming?
