add_subdirectory: Cmake Error

Error Message: 

-- +++ processing catkin package: 'ir_bx_lab'
-- ==> add_subdirectory(ir_bx_lab)
CMake Error at /opt/ros/noetic/share/catkin/cmake/catkin_workspace.cmake:121 (add_subdirectory):
  The source directory

    /home/isharm2/catkin_ws/src/ir_bx_lab

  does not contain a CMakeLists.txt file.

Call Stack (most recent call first):
  CMakeLists.txt:69 (catkin_workspace)

When I searched, I found this on Google, But not sure, How to use that? 

add_subdirectory(source_dir [binary_dir] [EXCLUDE_FROM_ALL])

I haven't had to do something like this for any other packages, for the packages I have worked with. Can you help me with the same?

Thanks in Advance.

Edit: After fixing the CMakeLists.txt absent error, I still get the same error.

Here is My CMakeLists.txt

Here is My CMakeLists.txt

this is not your CMakeLists.txt, but the one in the src space of your workspace. That's a default file, and you should not touch it, nor change it.

@gvdhoorn So, What will you suggest to solve this particular issue?

Asked by ishaniis on 2021-10-21 11:48:43 UTC

Is ir_bx_lab a ROS package? Does it have a package.xml? If it does, but the ir_bx_lab directory does not contain a CMakeLists.txt, you'll likely see this error. ROS 1 packages can not not have a CMakeLists.txt.

In any case: the problem is with your package, not with /home/isharm2/catkin_ws/src/CMakeLists.txt (as that's very unlikely to be broken).

Got it. Thanks for always helping out. It's the ROS package manufacturer gave us. I believe, my journey to learn ROS (and many of us like me) is incomplete without your prompt support here. Thank you!

Well it's something to check, so please verify what I wrote is correct.

If it isn't, something else might be wrong and that would need to be further diagnosed.

Asked by gvdhoorn on 2021-10-21 12:19:21 UTC

I guess during the transfer the package might be corrupted. I'll remove the current package from the workspace and will try again with it.

But ROS1 packages cant have their CMakeLists.txt ??

I don't understand what you mean by this.

Perhaps my use of a double negative confused you. I wrote:

ROS 1 packages can not not have a CMakeLists.txt.

by which I meant: you cannot have a ROS 1 package without a CMakeLists.txt. catkin_make would not know how to deal with it.

Asked by gvdhoorn on 2021-10-21 12:36:11 UTC

Ah! Got it!

The error occurs because there is no Create CMakeLists.txt in /home/isharm2/catkin_ws/src/ir_bx_lab and you should be able to proceed.

Usually, when you create a ROS package, you use catkin_create_pkg to create the base of CMakeLists.txt as follows.

catkin_create_pkg ir_bx_lab std_msgs rospy roscpp

See : http://wiki.ros.org/ROS/Tutorials/CreatingPackage

@miura I fixed the CMakeLists.txt error. But for this add_subdirectory error, I am unable to solve.
