Hello,

I have a problem when I use the roslaunch command to launch several executables. When I roslaunch my package, it should open 3 terminals and make the different command lines that I have put in 3 different scripts. But for one of these, the terminal opens and then closes immediately. I don't understand, because when I enter the command lines manually to launch this executable, it works.

Here is the script of my executable (its name is generation.sh) :

source catkin_ws/devel/setup.bash
rosrun rqt_mypkg generation

and the script of my launch file (test.launch) about this executable is :

<launch>
    <node name="gaitnode" pkg="rqt_mypkg" type="generation.sh" output="screen" launch-prefix="gnome-terminal --command" />
</launch>

I have made the executable executable and catkin_make my package without problem. I'm on ROS indigo and ubuntu 14.04.

So when I roslaunch it with :

roslaunch rqt_mypkg test.launch

for this executable the terminal opens, there is a message with source : not found, and then it closes. Normally the program should run and the terminal stay open. It works when I enter the commands manually.

Any explanation please ?

Thank you !
