Thanks.I did what you said,but it still error.

I am learning a ROS tutorial(Learning ROS for Robotics Programming). In chapter3_tutorials, i run fellow command:

roslaunch chapter3_tutorials example.launch

I got fellow results:

ERROR: cannot launch node of type [chapter3_tutorials/example6]: can't locate node [example6] in package [chapter3_tutorials]

My computer: Ubtuntu 14.04 indigo

Thanks

My code is following,just parts. pcl::PointCloud<pcl::fpfhsignature33>::Ptr fpfhs (new pcl::PointCloud<pcl::fpfhsignature33> ()); fpfh.compute (*fpfhs); pcl::visualization::CloudViewer viewer("My Viewer"); viewer.showCloud(fpfhs); while (!viewer.wasStopped()) { } when i run ,it will occur: /home/aicrobo/Documents/FPFH/fpfh.cpp:56: error: no matching function for call to 'pcl::visualization::CloudViewer::showCloud(pcl::PointCloud<pcl::fpfhsignature33>::Ptr&)' viewer.showCloud(fpfhs);

Thanks! ^

First,I have installed OpenNI < sudo apt-get install ros-indigo-openni-camera> Then,when i run: roslaunch rbx1_vision openni_node.launch It will occur: aicrobo@xty-K55VD:~$ roslaunch rbx1_vision openni_node.launch [openni_node.launch] is neither a launch file in package [rbx1_vision] nor is [rbx1_vision] a launch file name The traceback for the exception was written to the log file

Ubuntu 14.04 Why?Thanks

Thank you very much.I got it

Hi! When i run it in termial rosrun rosserial_arduino make_libraries.py . it will occur:

** Warning, failed to generate libraries for the following packages: ***

    pr2_description (missing dependency: convex_decomposition)

Why?Thanks!

When i "rosrun object_recognition_core detection -c rospack find object_recognition_linemod/conf/detection.ros.ork" in Terminal.It will occur error: "terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >' what(): boost: mutex lock failed in pthread_mutex_lock: Invalid argument Aborted (core dumped)" Thanks!
