title: device driver missing config.h
body: <p>So I start reading the book <a href="http://lwn.net/Kernel/LDD3/" rel="nofollow">http://lwn.net/Kernel/LDD3/</a> to write device driver </p>
  
  <p>The problem is the book used 2.6.10 while I'm using 2.6.35.X (on Ubuntu) and "config.h" is missing. I googled the problem and it turned out that config.h is removed. </p>
  
  <p><a href="http://stephane.lesimple.fr/wiki/blog/kernel_2.6.18_linux_config.h_problem" rel="nofollow">http://stephane.lesimple.fr/wiki/blog/kernel_2.6.18_linux_config.h_problem</a> suggests 3 solutions and the first 2 don't work to me ( I don't have autoconf.h ). The 3rd solution is the one that is over my head. If anyone can explain the 3rd or has other solutions, I'd appreciate.</p>
  
  <p>Thanks</p>
