ROS Kinetic 'catkin_make' Fails because PROJECT_NAME is set to Project

I have been using ROS Kinetic for a while, and today when I went to make a new catkin workspace following the ROS tutorials page (http://wiki.ros.org/catkin/Tutorials/create_a_workspace) I get a CMake Error stating that PROJECT_NAME is set to Project, which is invalid. I have never run into this issue with any of my other work spaces I have created.

I do not want to mess with toplevel.cmake out of fear of screwing up my other work spaces.

Any ideas why this is happening?

CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkin_package.cmake:91 (message):
  catkin_package() PROJECT_NAME is set to 'Project', which is not a valid
  project name.  You must call project() before calling catkin_package().

Thank you.

Solution

  • I was able to reproduce the above error you are getting. For that what I did is opened my CMakeLists.txt and commented the second line which defines the package Name, i.e., project(package_name). After that, I tried to build my package via catkin_make, but got below error(see the error inside yellow box):

    Then, I tried to build the same package after uncommenting the above line. This time I was able to build my package(test, in my case) successfully, without any error.

    CMakeLists.txt file contains project() as well as catkin_package() and the former function should be called before catkin_package() inside the file. So, project(package_name) is either missing from your CMakeLists.txt file or is commented.

    If it is missing, then manually add it. If it is there, but commented then uncomment it.
