Raspberry Pi V4L2 Compile Error How to Fix

I am using opencv with python on raspberry pi so according to tutorials on the internet I need the V4L2 driver. I'm following this tutorial to install the driver https://www.ics.com/blog/raspberry-pi-camera-module#.VAaCHqM0_YQ

However when I compile I get this error. I don't know what's the problem and have never ran into this problem before. How do I fix this. Thanks.

make[3]: Entering directory '/home/pi/v4l-utils/utils/v4l2-compliance'

The line numbers have changed somewhat in the 2+ years since this question was posted. It could have easily had more bugs back then with Raspbian 7 Wheezy on a Raspberry Pi 2 or classic Pi.

One correction to the webpage would be that it's better to run ./bootstrap.sh rather than autoreconf. I also write libjpeg-dev to avoid dependency problems with the too-specific libjpeg62-dev. Then the build and installation works fine today on Raspbian 9 Stretch (gcc 6.3):

sudo apt-get install autoconf gettext libtool libjpeg-dev
git clone git://git.linuxtv.org/v4l-utils.git
cd v4l-utils
./bootstrap.sh
./configure
make
sudo make install
