Why cannot I rosmake the image_pipeline package?

edit

Hi, I want to use the opencv in my ros, following the tutorials: http: // www .ros.org/wiki/openni_launch, I git cloned the image_view package(actually I use the command: git clone https :// github.com/ros-perception/image_pipeline.git, because image_pipeline includes image_view), however, I can not rosmake the package, it always shows like:

[ rosmake ] rosmake starting...
