cannot found linux-header for 3.2.27

[joe2act]

Hi,

I tried to compile simple device driver (hello.c) in RasPi. I already installed tool and some linux-headers in Raspbian. The current version is 3.2.27. But, I cannot find the 3.2.27's linux-header. How can I compile device driver with the right version of linux-header in Raspbian?

By the way, I can compile and run the same simple driver hello.c in Ubuntu Desktop.

pi@raspberrypi ~ $ sudo apt-cache search linux-header*

You could download the kernel src and do a make_headers

[ivanohé]

up, please

[shig]

So, as the standard debian kernel packaging system isn't used (the kernel and module are all in the raspberrypi-bootloader package), and the headers aren't distributed, you will need to download the source tree from the github at https://github.com/raspberrypi/linux/. You won't have to recompile it however.

Here a quick guide. I'm assuming that you already have build-essential/compiler/everything else you need in place anyhow, and just need the kernel specific headers and symbols.

Download the kernel source and unpack it with:

Code: Select all

sudo bash
cd /usr/src
wget  https://github.com/raspberrypi/linux/tarball/rpi-3.2.27
mv rpi-3.2.27
tar xzf rpi-3.2.27

Then we'll grab the config from the raspberry pi's running kernel, and get the source tree to prepare itself for module builds:

Code: Select all

cd raspberrypi-linux-*
zcat /proc/config.gz > .config
make oldconfig
make modules_prepare

What you will also need to build modules that will actually go into the new kernel is Modules.symvers. Luckily, someone has nicely put it in the raspberrypi/firmware github along with the pre-compiled kernel and firmware binaries, so we can just download the latest one from there:

Code: Select all

wget https://github.com/raspberrypi/firmware/raw/master/extra/Module.symvers

Then just make symlinks available in /lib/modules/[kernelversion]/ for the stuff you're compiling. Might as well put a symlink in for /usr/src/linux etc as well

Code: Select all

KSRC=`pwd`
pushd /lib/modules/`uname -r`
ln -s ${KSRC} source
ln -s ${KSRC} build
popd

pushd /usr/src
ln -s ${KSRC} linux-`uname -r`
ln -s ${KSRC} linux
popd

Apart from the time downloading, the rest should take about 10 minutes or so hopefully, depending on how fast the storage you've got available is. This will also take up about 630MB of space under /usr/src until you clean it up

Hope this helps

[ivanohé]

Yes it does. I needed such a clear tutorial. I'm bookmarking this page, thank you.

Hello,

I'm following these instructions and from the get go I'm having trouble. Anyone else having trouble with:

wget https://github.com/raspberrypi/linux/tarball/rpi-3.2.27

I'm getting an "ERROR 500: Internal Server Error".

Thanks.

Hi, I have a problem to make simlinks and so usb director won't to install (./installer.sh install-server => error E : Unable to locate package linux-headers-3.2.27)
Can you help me ?

Thanks

Thank you very much for your quick guide. It is a very clear and very helpful quick guide.

I'm getting an "ERROR 500: Internal Server Error".

Thanks.

Just try download RasPi kernel source code again. I can download it. The "ERROR 500: Internal Server Error" error is not your problem. It maybe a github server's temporary problem.

[geronymo80]

Ok it's done for me.

I don't know why the first time it doesn't work.
Now it's working

Thanks for the tutorial

I'm having the same problem as the one stated in the start of this topic but I must admit that I am a complete novice when it comes to linux. I've been trying to install drivers for my Iburst Usb pppoe modem and I need the full 3.2.27+ headers to get it done and I've had no luck following this tutorial to get things working.
I've listed the exact commands that I've tried using. I would really appreciate any help on a step I may have missed or that was assumed I should know.

I boot up my raspberry pi with the latest Raspbian image released 18-09-2012 which has also gone through the process of apt-get update and apt-get upgrade.

I log in with my username and password and then from the command prompt I have entered the following

sudo bash
cd /usr/src
wget https://github.com/raspberrypi/linux/tarball/rpi-3.2.27

The file then proceeds to download and completes without errors. (Should there not be a .tar or .gz extension?)

mv rpi-3.2.27
The mv rpi-3.2.27 command fails with an error about further parameters expected, which makes sense since it is a move command and a destination is required. But I don't know what that destination should be.

I then follow the rest of the commands which work but I think that by messing up the previous step, I have messed everything else up.

tar xzf rpi-3.2.27
cd raspberrypi-linux-*
zcat /proc/config.gz > .config
make oldconfig
make modules_prepare
wget https://github.com/raspberrypi/firmware ... le.symvers

KSRC=`pwd`
(what does the 'pwd' do and should I be placing it there or should it be something else?)
pushd /lib/modules/`uname -r`
(I'm not sure but I guess that by 'uname -r' it is meant that I should use 3.2.27+ as the value inside the ' ' since that is what is returned when I use the uname -r command seperately.)
ln -s ${KSRC} source
ln -s ${KSRC} build
popd

pushd /usr/src
ln -s ${KSRC} linux-`uname -r` (again, should this be 3.2.27+ instead of 'uname -r' ?)
ln -s ${KSRC} linux
popd

All the commands above are typed exactly in the sequence shown and I have not moved to different folders or run other commands in between.

To be honest, I'm stumped. I would really appreciate some help with this.

[aaa801]

You should be checking out the kernel from github using git
and not wget,
git clone https://github.com/raspberrypi/linux.git

Kernels and zips dont get on well

[neldlbk]

I'll give it a go and see how it turns out. Thanks

[girishadurrel]

Hey

For $KSRC='pwd'

very simply you could just type $pwd and copy paste the output $KSRC='output of pwd'.

Yes. For ln -s ${KSRC} linux-`uname -r` just replace uname -r with 3.2.27+

I use wget and there is no problem with that as well

Hope you will get it working.

[girishadurrel]

It really did help. Thanks a lot for the nice tutorial

Thank again

Following the step-by-step as shig posted, with the sole exception of the incomplete mv command, I managed to compile a wireless driver module.

However, when I try to modprobe the driver into the running kernel, I get the following error:

Code: Select all

Nov 21 21:54:47 raspberrypi kernel: [14319.160912] rt5370sta: disagrees about version of symbol wake_up_process
Nov 21 21:54:47 raspberrypi kernel: [14319.160950] rt5370sta: Unknown symbol wake_up_process (err -22)

Is there any chance something in the step by step needs to be changed for the most recent version of raspbian wheezy 2012-10-28?

For what it is worth, installing rpi-update and then running rpi-update eliminated the error and allowed the module to load.

hi there,

i was using this howto to compile a new driver module for my rtl8192cus based wlan dongle. however, i am unable to get the built module to work:

Code: Select all

# insmod 8192cu.ko 
Error: could not insert module 8192cu.ko: Invalid module format

dmesg tells me:

Code: Select all

# dmesg | tail -n1
[47934.353217] 8192cu: disagrees about version of symbol module_layout

Code: Select all

# modinfo ./8192cu.ko | grep vermagic
vermagic:       3.2.27+ preempt mod_unload modversions ARMv6 

i have already edited the main kernel Makefile to include

Code: Select all

EXTRAVERSION = +

- what else do i have to do to make this module work?

[eddieAng]

Hi,

I have a silly question. How do you create symbolic links?

KSRC=`pwd`: this is not a linux command. Is it a file that you alter? If so, where is it located?

Thanks in advance.
Ed

[bgirardot]

sym links:

Code: Select all

ln -s /path/to/file /path/to/symlink

for example:

Code: Select all

ln -s /etc/network/interfaces /boot/network-interfaces

Code: Select all

KSRC=`pwd`

is a bash shell command and assigns the output of the pwd command to the variable KSRC (which I think is a common variable to hold the path to the Kernel SouRCe)

Note the "back ticks" around the pwd command, those are not single quote marks, they cause the shell to execute the command and put its output in place of the command.

Hi,

I've followed the guide described above to get the linux-header but I seem to be getting an error whenever I try to compile a kernel module (dvbhdhomerun) for the raspberry pi (3.2.27+). I get the following error message:

Hi!
I'm trying to make trivial driver module, like this:

Code: Select all

#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
//#include <linux/fs.h>

MODULE_LICENSE("Dual BSD/GPL");
MODULE_AUTHOR("iiiiiiii");
MODULE_DESCRIPTION("ghjkhsgdkfhgksdjg");
MODULE_VERSION("0.1");

unsigned char ss[8];    // <-------------- change this size to 4 or to 0 will crash the kernel by "insmod"

//---------------------------------------------
static int __init led_init(void)
{
  printk( KERN_ALERT "Load module\n");
  return 0;
}
//---------------------------------------------
static void __exit led_exit(void)
{
  printk( KERN_ALERT "Unload module\n" );
}
//---------------------------------------------
module_init(led_init);
module_exit(led_exit);

This successfully compiled and loaded, but failed by "rmmod" with error:

libkmod: ERROR ../libkmod/libkmod-module.c:753 kmod_module_remove_module: could not remove 'test': Device or resource busy
Error: could not remove module test.ko: Device or resource busy

Also, if change of ss array to zero, insmod will make kernel "Oops" and kick to kernel debugger (kdb).
What i doing wrong?
