Re: [ros-users] Weird ros::ok() actionlib::SimpleActionClien…

Can you check what version of the *common* stack you are running?

*> roscd common
> cat CMakeLists.txt*

You'll see something like *rosbuild_make_distribution(1.x.x)*

isServerConnected was added in Common 1.2.0. If you have an up-to-date
C-Turtle release, it should definitely be there.

> should I also check that isServerConnected? before the waitForServer? or
isServerConnected just similar to waitForServer but return immediately? in
this case, it is probably better to use it in place of waitForServer.

In the actual implementation, *waitForServer* actually repeatedly
calls *isServerConnected
*until the timeout is reached or the server connects. Thus, for your case,
you should probably just use *isServerConnected*.
