[ros-users] [Discourse.ros.org] [Packaging and Release Management] OpenCV 3.3

[Zac Witte]

Is anyone else having a problem with the switch from opencv3.2 to 3.3 in kinetic? Unfortunately many of the packages in kinetic were compiled against 3.2, but its no longer available in the ROS ubuntu PPA. So currently I'm stuck unless I recompile all ROS packages that link against opencv myself. 

For example:

    zac at zac-prodesk:~/mbot$ rosrun rqt_image_view rqt_image_view 
    [ERROR] [1513885925.962331324]: Failed to load nodelet [rqt_image_view/ImageView_0] of type [rqt_image_view/ImageView]: Failed to load library /home/zac/mbot/devel/lib//librqt_image_view.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = libopencv_core3.so.3.2: cannot open shared object file: No such file or directory)
