Edit 1: Thanks for the answer. The node that I want to start is not self written and is used to use a hardware. The node uses nodelets and a launch file to start the node. When I use the launchfile and I sourced the setup.bash before everthing works fine. But I want to avoid a launchfile. Is it possible to start a node with nodelets without a launchfile? The node must start two nodelets at the same time.

Hi I wrote a ROS node and want to run the node on another target. So my plan was to copy the executable to the target and start it there with rosrun. The project is a CMake project and when i have the whole workspace on the target and do a source command before it works. But when i only copy the executable i am not able to start the node with rosnode name /path-of-the-executable.

Is there something missing?

best regards Harald
