opencv cmake command error: fatal error: linux/videodev.h: No such file or directory

Question

I follow jevois/INSTALL instruction for installing OpenCV 3.3.0.

My cmake command failed with Fatal error: linux/videodev.h: No such file or directory. What possible missing component?

The file does not exist in /usr/include/linux directory, but there is /usr/include/libv4l1-videadev.h. Here is the console output for cmake:

-- Detected version of GNU GCC: 54 (504)
-- Looking for ccache - not found

Answer 1

looks like maybe you are missing libv4l2-dev or similar.

Our recommendation to compile everything from source is 1) do you really need it? That would be only if you are going to change the Linux kernel of JeVois or its operating system, and 2) start by installing the Ubuntu packages from jevois.usc.edu, which will pull all the required dependencies (hopefully). Then proceed as explained in INSTALL. As part of installing the DEB packages from jevois.usc.edu, you will already get the pre-compiled and pre-installed OpenCV 3.3 for JeVois. On host, it is in /usr/share/jevois-opencv-3.3.0 and on platform it is in buildroot and will be flashed to microSD automatically by jevois-flash-card
