Hi I tried to launch the Djikstra demo, however the package cannot be located. I tried to run catkin_make to build it after clone from repository.
And tried to source /opt/ros/latest/setup.bash
However the pkg cannot be found. What should I do
It seems that catkin_make command is not building the package?
Strange it seems that this package is not built, but there is a hidden folder built in RIA OS that has this package, then I could launch it through the command:
roslaunch unit1_pp dijkstra_demo.launch
I mean there is a package built named unit1_pp, however the package dowloaded from git is called just unit1 without underscore pp. Well Nevermind, it worked
Hello @marcusvini178 ,
The package cannot be found nor built because it’s not in the src folder of the catkin_ws. ROS packages that are not inside the src folder can’t be found by the ROS system.
Maybe we can find a way to tell RIA guys so they can fix it in the instructions? I just stumbled upon this issue myself and through some fancy use of the tab key found the same as marcusvini178’s solution.
I think @albertoezquerro is right, but maybe they could add that in the instructions and tell us to run: source ~/catkin_ws/devel/setup.bash – it is basic ROS stuff, but it is confusing when you are going by the instructions and it isn’t working. --edit I didn’t realize that I was talking to one of the big guys. Would it be okay to contact you if there is anything problems on RIA?
Hello @matrhint ,
Yes, you are right. This kind of basic stuff (like sourcing the workspace) is covered basically in the ROS Basics Course, which we consider as the base and a requirement for more advanced courses. That’s why in some courses we are omitting some of these things. However, I agree that in some cases this can be confusing and it should be added nevertheless.
