Never happen before but If I create a directory mkdir -p catkin_ws/src and then enter catkin build I have the following error:

emeric@emeric-desktop:~/catkin_plan_ws$ catkin build

catkin_pkg.package.InvalidPackage: The manifest must contain a single "package" root tag

Besides the build and devel folders are created in my home directory not in the catkin one.

I guess I messed up something but I do not what and thus how to fix it.

Thank you for your help

The error message is saying there is more than one package tag in the package.xml file of one of your packages. Have you looked into this?

@PeteBlakerThe3rd - thank you for your answer. How is it possible because the catkin ws is empty, and I want to initialize it, so there is no package.xml at all. And I do not understand why the devel and build folders are not created under the catkin workspace...

The output shows:

Source Space:       [exists] /home/emeric/src
Log Space:         [missing] /home/emeric/logs
Build Space:        [exists] /home/emeric/build
Devel Space:        [exists] /home/emeric/devel

which suggests there is a .catkin_tools dir in $HOME.

It's likely that you forgot to cd catkin_ws after having run mkdir -p catkin_ws/src.

@gvdhoorn Yes that's right, I mean There was a .catkin_tools i my home directory and this is why catkin build issued an error because in the home_dir/src I have some standard c++ files. I removed the .catkin_tools and everything is working fine Thank you very much for your help
