2022-09-19 17:54:15 -0500 | marked best answer | Error when including .h from another package in the same workspace? Hello I have created a package GA_palnner for a custom global planner based on Genetic Algorithm. Under src of GA_palnner: CrossPoint.cpp , GA_global_planner_ros.cpp , GenericPathPlanner.cpp , Map.cpp , OccupancyGridMap.cpp , Path.cpp , Population.cpp Under include of GA_palnner: CrossPoint.h , GA_global_planner_ros.h , GenericPathPlanner.h , Map.h , OccupancyGridMap.h , Path.h , Population.h The GA_planner works successfully as global planner plugin and I am able to move my robot in Gazeo using this planner. Now, I created a package ros_global_planners_experiment to compare the performance of navfn and GA_planner ( gives the path length and running time for each). In ros_global_planners_experiment_node.cpp Gives me error: fatal error: GA_global_planner_ros.h: No such file or directory #include "GA_global_planner_ros.h" This is the package .xml and cMakeLists.txt for both GA_planner and ros_global_planners_experiment GA_planner package.xml GA_planner cMakeLists.txt ros_global_planners_experiment package.xml (more) |

2021-11-14 23:16:24 -0500 | marked best answer | Buffer error in ROS melodic Hi This code fragment is perfectly working in ROS kinetic: However, in ROS melodic, it gives error, I searched for it and tried to solve it by changing to: But, this gives error: Do not call canTransform or lookupTransform with a timeout unless you are using another thread for populating data. Without a dedicated thread it will always timeout. If you have a seperate thread servicing tf messages, call setUsingDedicatedThread(true) on your Buffer instance. I think it is an issue with Buffer constructor, but I don't know how to fix it? Help highly appreciated. |
