Hi! I'm new to ROS and I've been having some trouble getting started with the actionlib tutorial under Fuerte and Xubuntu 12.04.

I'm following the steps to create a Simple Action Server. In step 1.1, I used the following command to define the Fibonacci action, and then used the following command to generate the message files:

$ rosrun actionlib_msgs genaction.py . Fibonacci.action

This didn't work at first, and I needed to follow the guidance in another ROS answers topic to continue. The code that worked was as follows:

$ rosrun actionlib_msgs genaction.py -o msg/ action/Fibonacci.action

I followed the steps to edit CMakeLists.txt, created fibonacci_server.cpp, and copied the code given by the tutorial. If I make the project (with rosmake), though, the build fails with the follow error.

  Scanning dependencies of target fibonacci_server

Any assistance would be greatly appreciated. Thanks!

You need this in your CMakeLists.txt:

rosbuild_add_boost_directories()
rosbuild_add_executable(fibonacci_server src/fibonacci_server.cpp)
rosbuild_link_boost(fibonacci_server thread)

This changed in Fuerte. The tutorial explains it correctly, but you need to click on the fuerte button at the top of the page to see the new CMakeLists.txt update.
