Hi all! As seen from my previous posts, its been only about a month since I started using ROS. So pardon me if I am making any newbie error here.

I am trying to run a node on ros, but I am unable to do so. Here are the details:

package name: robot_node

ros version: ROS electric

Ubuntu version: Ubuntu Oneiric 32-bit

1) I opened a terminal and said


2) I went to the folder of the package and said rosmake

roscd robot_node


This works perfectly fine. I am able to compile with 0 failures.

3) My executable is called 'robot_node.cpp' so I do the following

rosrun robot_node robot_node

And then, I get this 'error':

[rosrun] Couldn't find executable named robot_node below ~/ros_workspace/ROS/robot_node [rosrun] Found the following, but they're either not files, [rosrun] or not executable: [rosrun] ~/ros_workspace/ROS/robot_node

There are a few things you should know that I already tried. These are

1) I checked the CMakeLists.txt for the package, and it does have the add_executable line.

2)I compiled all the first dependencies of the package separately, and they all compiled perfectly with 0 failures.

3) robot_node.cpp does have a int main() routine. :P

Any kind of help is greatly appreciated. Thanks for your time!

The output of make obviously shows an error, that's why no binary file is generated. The problem probably is your call to ADD_CUSTOM_COMMAND where you depend on another library. Did you check that the file libABBInterpreter.a really exists?

My suspicion is that you are not compiling the program at all or as you think you do. So, answer the following questions:

  • What is the output when you compile with rosmake and make?
  • What is your CMakeLists.txt?
  • Is there a binary robot_node in your package (possibly in bin/)?

Hey dornhege, here are your answers: 1) This is the output when I say make

2) This is the CMakeLists.txt

cmake_minimum_required(VERSION 2.4.6)


#set the default path for built executables to the "bin" directory
#set the default path for built libraries to the "lib" directory

set(ABB_PATH ${PROJECT_SOURCE_DIR}/../../ABBInterpreter)

 OUTPUT libABBInterpreter.a
 DEPENDS ${ABB_PATH}/lib/libABBInterpreter.a

#target_link_libraries(example ${PROJECT_NAME})


rosbuild_add_executable(robot_node src/robot_node.cpp)
target_link_libraries(robot_node -lABBInterpreter)

3) I checked the bin/ folder of the robot_node package. There seems to be nothing in it.

Question: How can I comment on your answer on this forum? It would be much easier than just creating a new answer altogether. Thanks!

You can update your original post by editing it. Regarding your problem check Lorenz' answer. There is a compilation error and thus no binary.

Hey dornhege and Lorenz, So I was able to solve the problem. The primary error, as you guys pointed out, lied in this one line


It should have been

Thanks for all your inputs! Also, just to make sure, I navigated to the ABBInterpreter folder and manually typed 'make' in the terminal just to make sure I had the libABBInterpreter.a file. Thank you guys once again :)
