roscore blocks your current terminal... You have to use another terminal for your commands.

Hi,everybody. I have tried every method I can find on the Internet, such as changing the image and depth mode to QQVGA30HZ, and turn the colour transformer to RGB8, but things were that it didn't help.

Hi,everybody! I got problem in using rviz to display the image from kinect.I installed openni_kinect to drive kinect, but once I run rviz to display PointCloud2 data, my computer crashed. How can I record the PointCloud2 data and display it on the rviz? Is there anything I should install besides openni_kinect?

Hi,everybody! I entered "roslaunch openni_launch openni.launch" in the terminal, then I got the following response.

......

I have been solving this problem all day long but I failed.

Hi, everybody! I have installed the openni_kinect(the camera I use is kinect), then I entered "rosmake openni_kinect --rosdep-install" and "roslaunch openni_camera openni_node.launch" in the terminal, the first command got executed successfully, but the second one failed. Here is some information in the terminal.

[rospack] warning: error parsing manifest file at [/home/llq/ros_workspace/pkgs/foobar/manifest.xml]?

Calibration hasn't been done to the camera, is this the cause? If so, is their any tutorial I can follow to complete the calibration?

I'm a beginner. I entered "roscore" in the terminal, but I couln't get response when entering other command. The response I got after I entered "roscore" as follow.
