2021-07-07 02:27:36 -0500	marked best answer	colcon build moveit2 failure because of moveit_ros_warehouse collect2 error I'm building moveit2 from this tutorial: moveit2_tutorials.picknik.ai/doc/getting_started/getting_started.html I'm on Ubuntu 20.04 and my ros2 version is foxy, which was built from debian. Rosdep returns all rosdeps installed successfully and moveit2's repos have been successfully cloned. I'm getting this when building: --- stderr: moveit_ros_warehouse /usr/bin/ld: libmoveit_warehouse.so.: undefined reference to `MD5' collect2: error: ld returned 1 exit status Here is the code from colcon build: :~/robotics/moveo_ws/ws$ colcon build --event-handlers desktop_notification- status- >--cmake-args -DCMAKE_BUILD_TYPE=Release Starting >>> geometric_shapes [Processing: geometric_shapes] [Processing: geometric_shapes] [Processing: geometric_shapes] [Processing: geometric_shapes] Finished <<< geometric_shapes [2min 1s] Starting >>> moveit_msgs Finished <<< moveit_msgs [7.18s] Starting >>> srdfdom Finished <<< srdfdom [0.52s] Starting >>> moveit_common Finished <<< moveit_common [0.27s] Starting >>> controller_manager_msgs Finished <<< controller_manager_msgs [2.03s] Starting >>> ros2_control_test_assets Finished <<< ros2_control_test_assets [0.25s] Starting >>> hardware_interface Finished <<< hardware_interface [0.98s] Starting >>> controller_interface Finished <<< controller_interface [0.66s] Starting >>> controller_manager Finished <<< controller_manager [1.18s] Starting >>> warehouse_ros Finished <<< warehouse_ros [0.45s] Starting >>> moveit_resources_panda_description Finished <<< moveit_resources_panda_description [0.26s] Starting >>> moveit_resources_panda_moveit_config Finished <<< moveit_resources_panda_moveit_config [0.28s] Starting >>> moveit_resources_fanuc_description Finished <<< moveit_resources_fanuc_description [0.26s] Starting >>> moveit_resources_fanuc_moveit_config Finished <<< moveit_resources_fanuc_moveit_config [0.27s] Starting >>> forward_command_controller Finished <<< forward_command_controller [0.63s] Starting >>> moveit_resources_pr2_description Finished <<< moveit_resources_pr2_description [0.30s] Starting >>> moveit_core Finished <<< moveit_core [4.59s] Starting >>> moveit_ros_occupancy_map_monitor Finished <<< moveit_ros_occupancy_map_monitor [0.48s] Starting >>> moveit_ros_planning Finished <<< moveit_ros_planning [2.06s] Starting >>> moveit_kinematics Finished <<< moveit_kinematics [0.98s] Starting >>> moveit_ros_warehouse --- stderr: moveit_ros_warehouse /usr/bin/ld: libmoveit_warehouse.so.: undefined reference to `MD5' collect2: error: ld returned 1 exit status make[2]: * [warehouse/CMakeFiles/moveit_warehouse_broadcast.dir/build.make:346: warehouse/moveit_warehouse_broadcast] Error 1 make[1]: [CMakeFiles/Makefile2:189: warehouse/CMakeFiles/moveit_warehouse_broadcast.dir/all] Error 2 make: ** [Makefile:141: all] Error 2 Failed <<< moveit_ros_warehouse [1.37s, exited with code 2] Summary: 20 packages finished [2min 27s] 1 package failed: moveit_ros_warehouse 1 package had stderr output: moveit_ros_warehouse 33 packages not processed I see this and look closer at ws/build/moveit_ros_warehouse/CMakeFiles and cat CMakeError.log.

2021-06-24 02:08:51 -0500	commented answer	Rosdep install not locating definitions [rostime] [catkin] [rospy] Noted. Thank you.
2021-06-24 02:06:23 -0500	marked best answer	Rosdep install not locating definitions [rostime] [catkin] [rospy] I'm following this tutorial: https://docs.ros.org/en/foxy/Tutorial... When I run rosdep install -i --from-path src --rosdistro foxy -y, I get the following output: `ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: rospy_tutorials: Cannot locate rosdep definition for [rospy] roscpp_tutorials: Cannot locate rosdep definition for [rostime] ros_tutorials: Cannot locate rosdep definition for [catkin] turtlesim: Cannot locate rosdep definition for [rostime]` My understanding is that rosdep looks for package names and keys. If I apt search rostime, for example, I get librostime0d as output. I have tried modifying package.xml with the search results. I have tried looking through rosdep's base.yaml as this question suggests: https://answers.ros.org/question/3501... but my rosdep isn't located at ros/foxy/rosdep, it's located inside /usr/lib/python3/dist-packages/rosdep2 and that folder doesn't contain a base.yaml file. When searching for the packages using dpkg -S I am able to find them. Where can I modify rosdep's definitions if not ros/foxy/rosdep/base.yaml or how can I otherwise instruct rosdep to locate the definitions?
