I want to change the version of opencv I am using to fix a problem I am having, or to at least rule out the version update as the problem cause. The problem is described here.

Downgrading the package using apt-get does not work because the package source is not available. I used the following commands to download an archived version(current version 3.3.1):

wget -O opencv_contrib.zip https://github.com/opencv/opencv_cont... unzip opencv_contrib.zip

The unzipped file is 'opencv-3.3.0'. Initially moved the unzipped file to the src directory of my catkin workspace and executed catkin_make from the top of the work space. The build exited with errors.

Next, I moved the file to the /opt/src/kinetic/include directory where opencv-3.3.1 was located. Then I changed the files cv_bridge-extras.cmake and cv_bridgeConfig.cmake in the directory /opt/ros/kinetic/share/cv_bridge/cmake/ to reflect the version information and location that I wanted. I executed catkin_make again. There were no errors but does not finish. It gets hung up at:

[ 93%] Building CXX object apriltags_ros/apriltags_ros/CMakeFiles/apriltag_detector_nodelet.dir/src/apriltag_detector_nodelet.cpp.o

After about 15 minutes I interrupt the build and the following output is produced:

^CTraceback (most recent call last):

If you want to use a different version of opencv you will have to build and compile it and install it into the right place. You should not be building anything inside /opt/ros That is designated as read only without super user privleges for a reason. If you are mucking around in there manually installing things.

Please review how to build and compile targets we have instructions for overlay workspaces at: http://wiki.ros.org/catkin/Tutorials/... and you should be installing opencv into the install space as well. ANd making sure that you've setup the appropriate environment variables so that your custom version of opencv is on the path.
