    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?

    Hi,
    did you follow the instructions from here (product datasheet)?
    https://store.codesys.com/opencv-for-ra ... re=default
    or here:
    "c:\Users\OpenCV for Raspberry Pi\3.5.11.0\Datenblatt OpenCV RaspberryPI_en.pdf"

    1.Installing OpenCV on Raspberry Pi:
    In order to use the library on the Raspberry Pi, OpenCV must already be installed on the
    Raspberry Pi. The specific version can be installed by means of the following command:
    sudo apt-get install libopencv-dev=2.4.9.1+dfsg-1+deb8u1

    1. Setting up the temporary file system
      For temporary buffering of images, a temporary file system is required in the /tmp folder.
      Commands for setting up the temporary file system:

    sudo -sAdd the following lines in the file /etc/fstab (if not already available):

    tmp /tmp tmpfs defaults 0 0
    Restart the system:
    reboot

    Installing the OpenCV component for the runtime system
    Then the OpenCV component for the runtime system still have to be installed.
    The Debian package "codesys_raspi_opencv_V3.5.11.0.deb" is located in the 'Opencv installation directory'.
    C:\Users\YourWindowsName\OpenCV for Raspberry Pi\3.5.11.0
    This could be installed by the Update Raspberry Pi command.

    The example project is here:
    "c:\Users\OpenCV for Raspberry Pi\3.5.11.0\CameraStreamOpenCVExample.project"

    yes
    This method in earlier versions of raspbian if it works.
    In the last version of raspian STRETCH are not in the repository "libopencv-dev = 2.4.9.1 + dfsg-1 + deb8u1"
    Thank you

    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,
