install ros nodelet
Hi I try to write my own ros nodelet but now i can not start it in my launchfile because it doesn't find the nodelet. When i source the deve/setup.bash file i can start it but now i want to start it in a launch file of another ros node. So i copied the content of devel/lib and devel/share to the /opt/ros/indigo/ lib and share folder. I opend a new shell sourced the setip.bash file from ros but the nodelet is not found with "rosrun nodelet declared_nodelets". What is the missing step that i can use the nodelet in my launch file?!
best regards Harald
Edit: I used the following example to implement my nodelet "https://github.com/cryborg21/sample_nodelet". It is a cmake project and the compilation works fine but there is no install target. What is the correct setup that i dont have to copy anything. The goal is to source the /opt/ros/indigo/setup.bash file and everythink works!
Edit: I use the git repo and compile the nodelet with the following commands
source /opt/ros/indigo/setup.bash
cmake .
make
source devel/setup.bash
roslaunch launch/sample_nodelet_class.launch
This works but i want to run the nodelet without sourcing the devel/setup.bash
Just a comment:
never do this. If you've setup everything correctly in your workspace, there is also no need to do this. Ever. You run the risk of overwriting base files of ROS and breaking it.
if there is no install target then you'll have to keep working with your
develspace andsourcethedevel/setup.bashinstead of something else.You'll have to tell us exactly what your development workflow is (ie: all commands, ..
.. workspace setup and layout, what you
source, when, where your package is, what commands you use toroslaunchthings, etc). Otherwise we cannot help you.re: edit 2: please see #q252478 for the correct procedure to build a package from source.
