u should go to the repo ros2_intel_realsense, and see the README, to install the dependencies, such as

sudo apt-get install ros-dashing-cv-bridge ros-dashing-librealsense2 ros-dashing-message-filters ros-dashing-image-transport

Check that! Good Luck!

Yeah those dependencies were installed previously and tried again also but no effect. pls see the screenshot.

sudo apt remove ros-dashing-librealsense2, give it a shot! (I am not sure if this will work!)

then I will use rm install log build -rf and colcon build --symlink-install to reproduce the error under ros2 workspace.

since your error caused by boost, check whether installed correctly!

see the error information: needed by 'src/libcv_bridge.so'. Stop. there is nolibcv_bridge.so in my ros2_overlay_ws/src , so if you can show me where the libcv_bridge.so file

[arun0303]

libcv_bridge.so file is not available in my ros2_overlay_ws/src directory and its available inside /opt/ros/dashing/lib directory.

more information about the ros2_overlay_ws/src/vision_opencv:

• git branch

[portgasray]

yeah, you should check the CMakeLists under cv_bridge, you'll find the valid information:

      # This is a bit of a hack to suppress a warning
      #   No header defined for python3; skipping header check
      # Which should only affect Boost versions < 1.67
      # Resolution for newer versions:
      #  https://gitlab.kitware.com/cmake/cmake/issues/16391

the sub-links in the issuse are very useful, especially the last one,

you should view it carefully and according to my experience, try the following: update line30 in ros2_overlay_ws/src/vision_opencv/cv_bridge
