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.

this is not your
CMakeLists.txt
, but the one in thesrc
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?
Is
ir_bx_lab
a ROS package? Does it have apackage.xml
? If it does, but their_bx_lab
directory does not contain aCMakeLists.txt
, you'll likely see this error. ROS 1 packages can not not have aCMakeLists.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.
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:
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.Ah! Got it!
