Compiling device drivers with Ubuntu 10.04LTS

Asked by Michel Halde on 2011-01-16

Hi,

I'm writing a custom device driver, and i would like to know how to build my modularized driver into Ubuntu 10.04LTS Kernel (2.6.32-27).

I've already installed the following directories: /usr/src/linux-headers-2.6.32-27, and /usr/src/linux-headers-2.6.32-27-generic. But no header .h files are there, just Kbuild, Makefile, Kconfig, etc.

Do we have build something to get .h files and objects from the Ubuntu's Kernel ? I need those files (.h and .o) for building my .ko file.

Thanks for your help.

Did you install the build-essential package, that usually gives what is needed.

I added the build-essential package, but i had no new .h files.

According to this documentation (https://help.ubuntu.com/community/Kernel/Compile), at the section "Reasons for NOT compiling a custom kernel", the first bullet describes exactly my case.

But i don't know which "linux-headers packages" to install...

The packages are already there into a stock ubuntu 10.04LTS desktop ? I have to "make" something under the /usr/src directories ?

You do need to install one of the linux-headers packages, if you don't already have that installed. You should install the one that corresponds to the linux package you have installed.

Open a Terminal window (Applications > Accessories > Terminal), type in the command "uname -r" (without the quotes), and press enter to run it. You should see something like:

2.6.35-25-generic

The part after the numbers indicates which kernel "flavor" you have installed, and that's the linux-headers "flavor" you should install as well. For example, if yours says "generic" like mine does, then you should install linux-headers-generic. If you want to do this from the command-line (i.e. within the Terminal), you can do so with the command:

sudo apt-get install linux-headers-generic

If you installed the package whose name is linux-headers-(version), where (version) is your kernel version, then that's just a virtual package that tells Ubuntu that you have chosen to install and maintain the linux kernel headers manually. You probably don't want that.

Thanks Eliah Kagan, that solved my question.
