[ros2] ros2 run [package] [executable] cannot find executable

asked 2018-01-17 19:12:56 -0500

I have a C++ project which consists of a number of packages that I'm migrating from ROS1 to ROS2; under ROS1 with catkin, I could build the project with catkin_make and run the executable with rosrun [package] [executable] (One of the packages is an executable, the rest are libraries or plugins).

I have installed ROS2 as per the binary install instructions https://github.com/ros2/ros2/wiki/Lin...

I have a workspace with my project cloned into it, and I believe I've finished migrating all of the package.xml and CMakeLists.txt files. The project can be built fully and the executable and libraries get put into the install directory as expected.

Unfortunately, after sourcing ./install/local_setup.bash (/opt/ros/ardent/setup.bash was sourced before building), the call ros2 run [package] [executable] returns "No executable found"

If I source the argcomplete setup in /opt/ros/ardent, I can try to tabcomplete after typing ros2 run and I can see that my package is listed as a possible completion, but if I run ros2 pkg executables, my package/executable pair is not listed.

I don't know what I have set up incorrectly.

Package.xml

<?xml version="1.0"?>
<package format="2">
  <name>sdsmt_simulator</name>
  <version>0.0.1</version>
  <description>2D simulation environment for robots running in ROS</description>

You need to install the executable to lib/<PKGNAME> in order to be found by ros2 run.

Specifically change RUNTIME DESTINATION bin/sdsmt_simulator to RUNTIME DESTINATION lib/${PROJECT_NAME}

Since the install rule also covers libraries I am not sure that will work on Windows.

That's true, it's better to install the libraries and binaries separately, so that the .dll's (considered part of RUNTIME by CMake) don't end up off the PATH. They belong in bin.

Right now i'm just trying to get the migration to work on Ubuntu; step two will be to try it all on Windows. Was there some documentation page that I missed which says this is where the executable needs to be?

I had the same problem and it happened because i didnt make the general colcon build on the main folder. I was trying to compile and run a specific project directly with colcon build --packages-up-to <name_pkg> and ros2 run <pkg_name> <node_name> without having the general files created when you use colcon build (you only have to do this once).
