ldd3: Linux Device Drivers 3 examples updated to work with recent kernels
Linux Device Drivers 3 (http://lwn.net/Kernel/LDD3/) book is now a few years old and most of the example drivers do not compile in recent kernels.
This project aims to keep LDD3 example drivers up-to-date with recent kernels.
The original code can be found at: http://examples.oreilly.com/9780596005900/
The example drivers should compile against latest Linus Torvalds kernel tree:
- git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git
To compile the drivers against a specific tree (for example Linus tree):
$ git clone git://github.com/martinezjavier/ldd3.git
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ export KERNELDIR=/path/to/linux
$ cd ldd3
$ make

---------4 Eclipse CDT integration is provided by symlinking the correct linux source directory with the ./linux_source_cdt symlink. The .project and .cproject files were setup using instructions in this link and assuming a symlink is setup in the local project directory to point to relevant kernel headers
This can be done on a system with kernel headers installed using:
ln -s /usr/src/linux-headers-`uname -r`/ linux_source_cdt
