This depends on how you've installed the roboearth package. If it's been installed as a binary (via, say, apt-get install ...), then editing it won't do anything.

To build it from source, you'll need to download the source using rosinstall (see the docs for rosinstall, and the "source" line in the list at the very top of the roboearth wiki page). Then, build it using rosmake. Because you're building it from source, any changes you make will take effect as soon as you recompile.

Modifying the roboearth package is definitely legal, because it is an open source project.

@Mac explains that you will need to download the source and build it. Test that version first, before making your changes (to make sure the build was successful). Then modify the header, rebuild and test.

You may want to contribute your changes back to the roboearth developers. If they apply them to their source repository, then future versions will work for you without additional effort. Contact the developers directly so they can tell you the preferred way to request enhancements and submit patches.

Did you recompile it after saving it? Did you change something that actually alters the behavior of the program? Are you calling roboearth stuff directly, or are you using it as a library for a different package? If the latter, you need to call rosmake _each time_.

@Mac an @joq......i think i have made a foolish mistake....there is no such thing to edit header file in roboerath..coz first i thought to change value for kinect video speed in roboearth file but actuaaly there is no such thing related to kinect video speed in any roboearth file...im such a fool..

That's OK. We all make mistakes. Good luck!
