How to 'catkin_make clean' just one package?

edit

Thanks Dirk. Unfortunately, running 'make clean' in any directory under ~/catkin_ws (including the root) results in the following error:make: * No rule to make target `clean'. Stop.

Either call catkin_make clean in the root of the workspace or plain make clean in the subfolder build.

D'oh! I missed trying it in the build directory. OK thanks. But my original problem remains. So there is really no way to completely remove a catkin package without having to rebuild other packages? This seems mildly tedious...

No, there is no alternative. But rebuilding your workspace is only a matter of a couple of seconds. If your are not yet using ccache you should give that a try.

Thanks for the ccache tip. Unfortunately it doesn't appear to provide any noticeable speedup even though it is now symlinked to cc and gcc. Rebuilding my workspace can take many many minutes if it includes some packages like ecto.

ccache is only faster after the first build. If you use catkin_make_isolated you can remove a package by deleting the build/pkg_name and devel/pkg_name folders. But for catkin_make everything is in a shared build and devel space so you can't do that.

Thanks for the pointer to catkin_make_isolated which I did not know about. Looks promising!

Another option to clean up could be:

$ cd ~/catkin_ws
$ rm -r build devel install
