About how to run and use a package

edit

thanks , but when i use the 'Edit ' the output still ERROR: cannot launch node of type [rotoscan_node/rotoscan_node]: can't locate node [rotoscan_node] in package [rotoscan_node] maybe ,i can try to build it next .

You need to build it using catkin_make, there is no other way. This is C++, you cannot execute it in any other way.

I actually used the catkin_make into my catkin workspace , but it still like this error ,is there any other solutions ?

And after catkin_make, you remembered to do source /path/to/your/catkin_ws/devel/setup.bash?

of cause i have , maybe , it is not a correct package ?

Please update your original question with the exact steps (on the command line) you took to create your workspace, download the package, configure and build it.

The catkinized version of the package I linked works fine for me here locally -- after compilation and source-ing.

It seems that when i installed the rotoscan node, it can be always output catkin_make error , if i delete , it will be ok

That is why I asked you to update your question with how you created your workspace.

You most likely forgot to install all dependencies. Do you have the timeutils package in your src space as well?
