I am working through the Navgation Stack Tutorials on

I am using Ubuntu 16.04LTS and ROS Kinetic.

The issues occur when building the code (Step 5 from link below):

I feel the issue is happening at Steps 3 and 4, when I am broadcasting and then using a transform.

I am being told to save the text files as src/tf_broadcaster.cpp and src/tf_listener.cpp.

But you cannot save a file using /, so I am saving them in my src folder as tf_broadcaster.cpp and tf_broadcaster.cpp.

I then edit the CMake.txt file in this folder to include the below text:

add_executable(tf_broadcaster src/tf_broadcaster.cpp)

add_executable(tf_listener src/tf_listener.cpp)

target_link_libraries(tf_broadcaster ${catkin_LIBRARIES})

target_link_libraries(tf_listener ${catkin_LIBRARIES})

I already know before I build my code that there will be an error as it is calling to add executable src/....

I build the code using the commands:

cd ~/catkin_ws/


I then get the error below:

CMake Error at robot_setup_tf/CMakeLists.txt:208 (add_executable):
  Cannot find source file:

What am I doing wrong here? Am I saving the files incorrectly in steps 3&4?

Could you update with the folder struct of the folders using the command "tree" (sudo apt install tree). In the package folder (Not in the workspace, the package [catkin_ws/src/robot_setup_tf])

When I run the command [catkin_ws/src/robot_setup_tf], I get the message [bash: catkin_ws/src/robot_setup_tf: Is a directory], so I am unsure if I am now in the package?

I ran [sudo apt install tree] after the first command above and it installed with no issues. (see next comment please)

However, when I run [catkin_make] again I get some different errors

Teo Cardoso, would you have any advice on this?

jimc91 gravatar image jimc91  ( 2020-07-07 08:50:19 -0500 )edit

When I made the first comment I was aiming to see your folder struct because this error can be caused by missing files or something like this.

The command tree you generate something like this, could you post this struct of your package?

├── CMakeLists.txt

├── package.xml

├── scripts

│   ├──

│   ├── map2.png

│   ├── map3.png

│   └── map4.png

└── src

Sorry for the delay, here is the structure of the package:

jamescoady@jamescoady-Inspiron-5579:~$ cd catkin_ws/src/robot_setup_tf

jamescoady@jamescoady-Inspiron-5579:~/catkin_ws/src/robot_setup_tf $ tree
├── CMakeLists.txt
├── include
│   └── robot_setup_tf
├── package.xml
└── src
    ├── tf_broadcaster.cpp.odt
    └── tf_listener.cpp.odt

3 directories, 4 files

I edited both files to remove .odt but still get the exact same error when running catkin_make. I have not copied and pasted it as it is the same error in my messages to you on July 2nd.

Just to be sure the issue is with the current package that I am using. I removed robot_setup_tf from my scr space and have run catkin_make again with no errors.

In the files 'tf_listener.cpp.odt' and 'tf_broadcaster.cpp.odt'.

Remove the '.odt' from the name. The file name should be tf_broadcaster.cpp only. Same to the listener.

I guess this should solve your problems.

I went back and started again. When saving tf_broadcaster.cpp and tf_listener.cpp, I saved both as text files then ran catkin_make again and there was no issue.
