Is the method not implemented or am I missing something in the linking?

ros fuerte on ubuntu 12.04

Could you include the version of ROS you are using, your Ubuntu version, your manifest.xml file and your CMakeLists.txt ?

It appears that this may actually be a bug, as I was able to reproduce it on my Fuerte/12.04 install as well.

It seems that while it is documented in the API, and there is a declaration in the header file, but it does not seem that the method is actually implemented anywhere. This explains why you would see a linker error.

I filed a ticket on code.ros.org so that this can get resolved.
