linux/videodev.h : no such file or directory - OpenCV on ubuntu 11.04

Question

I tried to install OpenCV2.2 on Ubuntu 11.04. But OpenCV compilation fails stating an error related to linux/videodev.h file. File available in /user/includes/linux is name

Answer 1

The current answer is incomplete. Installing libv4l-dev creates a /usr/include/linux/videodev2.h but doesn't solve the stated problem of not being able to find linux/videodev.h. The library does ship header files for compatibility, but fails to put them where applications will look for them.

sudo apt-get install libv4l-dev
cd /usr/include/linux
sudo ln -s ../libv4l1-videodev.h videodev.h

This provides a linux/videodev.h, and of the right version (1).
