I have some problem when I excute [roscore]. This is error message [You must specify a valid interface name]. I refer others solution like excute [pip install --upgrade netifaces], but it still has some question. When I excute [pip install --upgrade netifaces], I get this [cannot fetch index base URL. Counld not find any diwnloads that satisfy the requirement netifaces. No distribution at all found for netifaces]. Thank you for any advises.

Hello guys, I have some problems when I want to "cmake" this package "rxtools". Then, I got some errors like following messages:

CMake Error at /opt/ros/groovy/ros_catkin_ws/install_isolated/share/catkin/cmake/catkinConfig.cmake:77 (find_package): Could not find a configuration file for package wxpython_swig_interface.

Set wxpython_swig_interface_DIR to the directory containing a CMake configuration file for wxpython_swig_interface. The file will have one of the following names:

wxpython_swig_interfaceConfig.cmake
wxpython_swig_interface-config.cmake

Call Stack (most recent call first): CMakeLists.txt:4 (find_package)

-- Configuring incomplete, errors occurred!

But I already set the "wxpython_swig_interface_DIR" to the directory "/opt/ros/groovy/ros_catkin_ws/install_isolated/share/rx/wxpython_swig_interface/devel/share/wxpython_swig_interface" that contain "wxpython_swig_interfaceConfig.cmake". I have no ideas why I got this error. Thanks for any answers!

I think I find the reason why I can't rosmake "kobuki_description". Because the "kobuki_description" folder doesn't have "Makefile". On the other hand, I can't use "sudo apt-get install kobuki" to install kobuki, this is error I get "Unable to locate package kobuki"

Sorry, I don't know how to build the package which I use "git clone" from here "http://www.ros.org/wiki/kobuki"...

After download it, I export ros path to "kobuki". But i still can't find "kobuki_description" package when I use "rospack find kobuki_description"

Thank CarolineQ! I already install create_description package.Then, another error: "ResourceNotFound: kobuki_description". But I can't install this package, I download this package from here "http://www.ros.org/wiki/kobuki_description", using "git clone".

I use ubuntu on PandaBoard and follow the tutorial to install ROS: http://www.ros.org/wiki/groovy/Installation/PandaBoard/Source

In the tutorial step 3.1.1 Create a catkin Workspace, I install Robot (not ROS_Comm)

The bold type is the all message when I launch "rosluanch turtlebot_bring minimal.launch", but it doesn't seem to miss package. I follow this tutorial "http://www.ros.org/wiki/groovy/Installation/PandaBoard/Source" to install ROS.

Thank you for your response. My operating system is Ubuntu 12.04, but I don't know what you mean "Your path seems to indicate that you did .... precompiled binaries if you are using Ubuntu". Can you explain more detail? Thank you.

Thank you, CarolineQ. I have turtlebot_description package and install xacro package after your suggestion. Then, I launch "rosluanch turtlebot_bring minimal.launch" again. But still have some error when I launch. Following message is the error message::

Hello guys, I have some questions about turtlebot. I use ubuntu 12.04 and Groovy. I refer this www.ros.org/wiki/groovy/Installation/PandaBoard/Source(Installing on PandaBoard) and www.youtube.com/playlist?list=PLDC89965A56E6A8D6(youtube, tutorial1 to tutorial6).

First, I don’t know how to bringup the turtlebot. In the other tutorials, you can use "roslaunch turtlebot_bringup minimal.launch" or "sudo service turtlebot start". But it don’t have "turtlebot_bringup minimal.launch" in the pandaboard tutorial. On the other hand, when I use the command "sudo service turtlebot start, it have error message "turtlebot unrecognized service" Second, I want to move the turtlebot in real Environment with the keyboard(like as youtube tutorial), but I don't know how to do this. Does anyone have good suggestion or tutorials? Thank you very much!
