I am having problem for Exercise 3.1 for interacting with a service pragmatically!
I created a package named service_client_pkg with dependency roscpp.
in src folder simple_service_client.cpp was created and the code was copied from the instructions.
I created a launch file, the Cmake list was modified as follows:
In instructions (point number 3) :
Create a launch file for launching this code. Keep in mind that, in order to be able to call the /trajectory_by_name service, you need to have it running.
I started the service as follows:
user:~/catkin_ws$ roslaunch trajectory_by_name start_service.launch
I see still red errors with the simple_service_client.cpp file
I tried compiling the package and encountered the following error:
Could you please suggest the correct way/steps for compilation of project?
Or which step i haven’t executed correctly?
Thank you very much in advance!!
First of all, welcome to the community!
You can ignore the red lines in the cpp file.
As for the compilation error, it’s because of a typo in the
CMakeLists.txt file, on line
146, as pointed out by the error message. Perhaps you mistakenly deleted some characters, included an invalid character, or missed out a brace on the line. Please check.
Thank you very much I cross checked my
But now I have another error:
Also my service is running!!
You need to include the package
trajectory_by_name_srv as dependency in your package. I apologize that this was not mentioned in the notebook. We will update the notebook ASAP.
The easiest way is to add it as a dependency when creating the package:
catkin_create_pkg service_client_pkg roscpp trajectory_by_name_srv
But since you have created the package already, just modify your
package.xml as follows:
find_package(catkin REQUIRED COMPONENTS
trajectory_by_name_srv as a dependency, just like
Please let us know how it goes.
Thank you very much for the help. It did worked.
Also I would like say that please hint out that in launch file following should be included:
<include file="$(find trajectory_by_name)/launch/start_service.launch"/>
