That sounds great! What about message generated header files ? Are they GPL as well ?

Hey there,

I installed properly ROS Hydro, and I've been using it for quite a while. However, after coming to office the next day. I get the following error

zsh: command not found: roscore

This is weird because I am sourcing setup files for both ROS installation and catkin/rosbuild workspaces. Rosbuild is overlayed with catkin/devel. Also rosdep is working, and I have all enviromental variables except ROS_ROOT after launching new terminal. Thought exporting manually ROS_ROOT doesnt help, and when I source manually /opt/ros/hydro/setup.zsh and after rosbuild/setup.zsh or catkin/devel/setup.zsh, I lose all again.

I tried reinstalling ROS, but that didn't fix the problem.

Anyway had a similar problem?, because this sounds really weird to me.

Ok I have roscore in /opt/ros/hydro/bin, and if I source /opt/ros/hydro/setup.zsh then it works, or if I manually add /opt/ros/hydro/bin to my $PATH, then it crashes because $PYTHONPATH is not setup correctly.

However, the problem is that sourcing either catkin_ws/devel/setup.zsh or rosbuild/setup.zsh breaks my general ROS enviromental variables, it overwrites them. For example I lose from $PYTHONPATH dist-packages, /opt/ros/hydro/bin from the $PATH, and so on.

Does anyone have similar issue ?

UPDATE:

I just don't want to edit all enviromental variables by hand after sourcing catkin_ws/rosbuild setup files, so there has to be one solution to it.

Thanks for fast response,

which roscore cannot find roscore, and ros-hydro-roslaunch is installed and up to date, also I have working python at /usr/bin/python.

Problem solved itself too, I don't know why but launch script was not reading properly ip address from NAO_IP env variable, and was crashing for this, now everything works

I have the same problem on Hydro and NaoQI 1.12.5 , nao_tactile is dying when launching nao_driver with this error

Exception TypeError: "in method 'module_getName', argument 1 of type 'AL::module *'" in <bound method NaoTactile.__del__ of <__main__.NaoTactile;  >> ignored

nao_speech is available though, and I can publish to /speech topic. However, nao_camera is not working, I can't launch the process, because it's dying after throwing exception

Traceback (most recent call last):
File "/opt/ros/hydro/lib/nao_driver/nao_camera.py", line 162, in <module>
    rospy.logerr('Something went wrong: %s' % (e.strerrror) )

I have managed to find the place, and it's throwing it on:

    self.nameId = self.camProxy.subscribe("rospy_gvm", self.resolution, self.colorSpace, self.fps)

Any ideas why that could happen, I am launching it with

PYTHONPATH=/opt/ros/hydro/lib/python2.7/dist-packages:/home/asiron/software/naoqi/lib:/home/asiron/software/naoqi/python
LD_LIBRARY_PATH=/opt/ros/hydro/lib:/home/asiron/software/naoqi/lib

I have similar issue, I can't launch the process because it's dying in the middle of the launch, I have managed to get to know, and it's dying at the same line camProxy.subscribe("rospy_gvm", self.resolution, self.colorSpace, self.fps)

Could you please tell me what was your problem, I have been having the same problem for 2 weeks, and I have yet to solve it, my env variables seem ok to me
