run "rosdep install -r --from-paths ." error

[QinZiwen]

When I was run "rosdep install -r --from-paths .", some errors show me as following:

turtlebot@turtlebot-HP-ZBook-14-G2:~/catkin_ws/src/iai_kinect2$ rosdep install -r --from-paths . ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: kinect2_viewer: Cannot locate rosdep definition for [kinect2_bridge] kinect2_calibration: Cannot locate rosdep definition for [kinect2_bridge] kinect2_bridge: Cannot locate rosdep definition for [kinect2_registration] Continuing to install resolvable dependencies... All required rosdeps installed successfully

Some assistes show as following writing by author: rosdep will output errors on not being able to locate [kinect2_bridge] and [depth_registration]. That is fine because they are all part of the iai_kinect2 package and rosdep does not know these packages.

what should I do, my rosdep can just know these packages. Thank you very much!

You don't have to open one issue twice. #296 This is ok, you can ignore it.

When I run " catkin_make ", some errors show me again:

Invoking "cmake" failed

when I try to delet iai_kinect2/kinect2_registration/CMakeLists.txt:77 , "catkin_make" can pass, but iai_kinect2 could not work.

[kohrt]

Install OpenCL, pull the latest changes, remove devel and build folders and run catkin_make again.

[QinZiwen]

Yes, iai_kinect2 works nice now. Thank you very much @wiedemeyer . However I thking that OpenCL is not optional but integrant.

[kohrt]

No, it's not. You either have to have Eigen3 or OpenCL or both installed.

[QinZiwen]

o, I see, thank you again！
