[SOLVED] Examples of Linux Device Drivers Book

[rajainnov]

I am trying to compile the sources of examples of the book, Oreilly Linux Device Drivers on ubuntu
which has the kernel version 2.6.24-24-rt installed on it.

In particular, when trying to compile snull (Network Device Drivers Examples), lots of errors prevent from the driver to get built.

/home/ubuntu/sample-c/examples/snull/snull.c: In function ‘snull_poll’:
/home/ubuntu/sample-c/examples/snull/snull.c:289: error: ‘struct net_device’ has no member named ‘quota’

make[1]: Leaving directory `/usr/src/linux-headers-2.6.24-24-rt'
make: *** [default] Error 2

Can someone help me fix the problem.

The problem is because of the change in Kernel API, to the extent that even struct net_device has changed.

So please do share with me if there is some kind of a patch to the examples code of the book, which will make the build successful.

Or another solution is also welcome.

Thanks in advance.

I fixed this problem, the modified sources are available on cs.fsu.edu /2.6.25/ldd-examples/ website.

Thanks
