Thank you

Try install or put libudev and libudev-dev before to have include file in your include path.

And if nothing else works, I would delete the udev build directory and do it again. Untar both tarballs again as described. Then copy and paste the commands; especially that large block of commands (copy and paste it all-at-once). That particular page in the book is sort of a busy one; easy to botch. I just finished a new 7.1 system and, unlike the 7.0 book which had a few errata, this one was smooth sailing straight through including that udev page you're stuck on. I had to do nothing special to get past that.

I suggest use "ldconfig" command after installation complete.
This command updates library cache to have proper file in your lib directory.
