I get the following errors when trying to install the OpenCV to the raspberry pi 3 with the Raspian Jessie.
I run the command sudo apt-get install libopencv-dev=2.4.9.1+dfsg-1+deb8u1 and get the following errors.
The raspberry has the internet connection and can ping 93.93.128.193.
I plan to use a standart web cam. So do I need to install anything else?

Thanks,

hia

The opencv librarian - 1.0.0.0, when adding it in a codesys 3.5 sp11 project generates 479 errors without being resolved.
Has anyone tried it with another version of codesys?
