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?

Debian Configuration :: Building A Loadable Kernel Module?

Jul 30, 2010

I upgraded my kernel in my Debian Lenny to version 2.6.32-bpo.4-amd64 to fix a problem with a software and ALSA-related issues. The thing is that now, when I boot, eth1 is not enabled and I have to "load" (I guess) the driver each time. To do this, I go to the folder where all the files for the drivers are and I run:

modprobe lib80211
and then
insmod wl.ko

That I got from the readme file. That gets the wireless working perfectly again, but when I reboot the wireless is dead again and I have to run the commands above again. I imagine that what I should do is to build the driver again, for my new kernel. However, according to the readme file, before I need to install linux-headers-generic and build-essential. With build-essential, it says it's already the newest version, and with the linux-headers, I don't know which one should I install for my kernel! I thought it would be the linux-headers-2.6.32-bpo.4-xen-amd64, but when I tried that, this is what happened:

debian:/home/hernan/Programas/hybrid_wl# apt-get install linux-headers-2.6.32-bpo.4-xen-amd64
Reading package lists... Done
Building dependency tree

[code]....

So the warning says something about the MODULE_LICENSE being missing... how to build the driver again to make it load each time I boot?

Debian :: Error - Building The VirtualBox Guest Additions Kernel Module

Jun 16, 2010

I am running Lenny and using VirtualBox OSE 1.6.6. In order to try squeeze I installed it in a VM. I tried to install Guest Additions also, but i get this error:

Software :: Specifying GCC Version For Building Kernel Module

May 1, 2011

I'm trying to set up a netbook I purchased that has a lot of more recent hardware, and so I'm having to compile some kernel modules on my own. I've installed Debian on this particular system, and so the version of gcc that was used to compile the kernel is older than the one currently in the repos. Now, I've installed the version I need, but can't remember how to specify building the modules in question with said version.

I've done this in the past, and recall temporarily changing some variable to use the different version, but it's been a while and I just can't remember. Is there an easier way to do this on the fly for any compilation? Or is changing a variable necessary? If there is no way to explicitly specify gcc version used prior to a compilation, could someone remind me of the variable I need to change to use x.x.x version?

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�

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

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

Debian :: Recompiling Changed Code When Building Kernel Debs

Jan 15, 2016

How do I force recompilation of the kernel .deb packages. After a small change I make to the sources without having to clean the sources and recompile the whole kernel again?

Code: Select all$ fakeroot make -f debian/rules.gen setup_i386_none_686
$ fakeroot make -f debian/rules.gen binary-arch_i386_none_686 binary-indep

Calling the second command again does not recompile the modified code, just recreates the .deb packages.

If I use:

Code: Select all$ make -f debian/rules clean before the build command, then it will recompile everything which takes ages.

How can I force recompilation of the files/objects I changed (and dependencies)?

I use this guide: [URL] .... ('Building only a single kernel variant' section)

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...

Debian :: Building Kernel - Initrd Fail And Nvidia Can't Find Source

Feb 25, 2010

So I'm building a custom kernel cuz I want the fbcondecor patch in my kernel. I use the same .config that 2.6.32 debian kernel package comes with. This kernel runs perfectly. I pass --initrd to make-kpkg when building the package but no initrd is built when I install it so I have to make it using "mkinitramfs -o /boot/initrd.img-2.6.33 2.6.33" to get it to boot. Now when I try to build the nvidia drivers it complains it can't find the source. I did build kernel_headers and installed them also the source is in /usr/src/linux. I also tried to specify the path by passing --kernel-source-path= to the nvidia script but no change. What is going on? I've done this fifty times before and never had any problems. Has there been some changes to how debian kernel packages are built? EDIT: Just thought I'd add some info about the steps I took.

Code:
tar xjvf linux-2.6.33.tar.bz2
ln -s linux-2.6.33 linux
cd linux
patch -p1 < ../fbcondecor-0.9.6-2.6.33-rc7.patch
cp /boot/config-2.6.32-trunk-686 ./.config

make menuconfig Loaded .config then I removed support for maxtorfb, tile blitting and some sirrusfb thing, nothing thats relevant to my system. Changed cpu from Pentium 4 to Core 2 and added framebuffer decor
support from my patch, exited and saved. Then:

[Code]....

EDIT2: I have now tried to build 2.6.32.8 in the same way with the same strange results, anyone have any thoughts as to what I'm doing wrong just throw it at me, I'm getting desperate and running out of ideas. I've checked all the kernel source symlinks and everything looks good.

Programming :: Assign IP Address / Renew DHCP From Kernel Module?

May 14, 2010

I'm currently working with wireless network kernel module.

This device initialiy gets its IP address by using DHCP,
but the problem is sometimes the new IP assigned for internal reason.

So what I want to do is assigning new(changed)IP address into exsiting
interface, or occuring DHCP renew event to cause update IP from kernel
level. This shold be done without user's intervention, so whenever the
kernel module detects IP changed(via underlying wireless
communication), it automatically correct update its IP address.

Q1) any functions or api to cause DHCP renew event from kernel level?
Q2) or any functions or api to assign IP address to specific interface?

Debian Configuration :: Add New AMD PCI-IDs To Kernel Module

Jul 9, 2015

I recently bought an AMD R7 360 videocard and I'd like to use the free Radeon driver.

Problem is, PCI-ID 0x665f is not present in Jessie's 3.16 kernel sources. The hardware however is supported, it's just not recognized. So I'll have to get the Debain sources and patch include/drm/drm_pciids.h

From the 4.1rc1 kernel I know what to patch and where.

Debian Programming :: GCC Freezes When Building Package On Raspberry Pi

Apr 27, 2014

I'm trying to compile a project on my raspberry pi with little success. I typed export DH_VERBOSE=1 and added -v to the gcc options in the Makefile to see what was going on and this is the output. I'm trying to compile hda-jack-retask to get the raspberry pi headphone jack set to be a microphone jack. I want to be able to use the microphone jack as the input to xoscope, an oscilloscope program.

Code: Select allpi@raspberrypi ~/~diwic/+junk/hda-jack-retask $ dpkg-buildpackage
dpkg-buildpackage: source package hda-jack-retask
dpkg-buildpackage: source version 0.20120113
dpkg-buildpackage: source changed by David Henningsson <david.henningsson@canonical.com>
dpkg-buildpackage: host architecture armhf
 dpkg-source --before-build hda-jack-retask

[Code] ....

And it sits here for at least 24 hours. Alternatively, It looks like this program is part of the alsa-tools package in Ubuntu, but not in Debian. Need to figure out this freezing issue, should I pull down the Ubuntu source and build a debian package from that?

Debian Programming :: Building Gtk-sharp2 Binaries On Testing

Nov 20, 2014

I am trying to build architecture specific binaries of gtk-sharp2. So far I have been unable to get gtk-sharp2 to build even without specifying a specific architecture. I got the source with apt-get source gtk-sharp2 and attempted ./configure, make, but it fails to build with the error message:

Code: Select allNo rule to make target 'thread.c', needed by 'thread.lo'.

I've also tried downloading the source directly from the mono project [URL] ...., but when building it fails with

Code: Select all#error "Only <glib.h> can be included directly."

This site [URL] .... provides a patch to fix the error, but when I applied it I got the same error.

I think the Debian version applied the patch correctly, but for some reason I still get that other error message.

These message outputted by configure may point to the problem:

"checking if gcc supports -fno-rtti -fno-exceptions... no"
"./configure: line 12920: enable_msi: command not found"

Always the same error when booting. After a period of time, (Graphical User Interface) the mouse click no longer operates, also text input isn't possible.

I had no access to the system at all, even crt alt F1 stopped working, also text input was no't possible. so reinstall was the only option. Maybe there is a connection with this two errors.

I've reinstalled Debian 8 several times. Still, both errors stay.

The same happend again (in the GUI) is nothing possible, no txt input, no mouse click), but now I have access to the system, ctr/alt F1 is working.
