simple action client freezes dring client object declaration.

`#include <ros/ros.h>
#include <actionlib/client/simple_action_client.h>
#include <actionlib/client/terminal_state.h>
#include <roadmap_global_planner_msgs/DoPatrolAction.h>

int main (int argc, char **argv)
{
ros::init(argc, argv, "fakee");
std::cout<<"fakee"<<std::endl;
// create the action client
// true causes the client to spin its own thread
actionlib::SimpleActionClient<roadmap_global_planner_msgs::DoPatrolAction> ac("patrol_controller", true);
std::cout<<"fakee"<<std::endl;
while(!ac.waitForServer(ros::Duration(5.0))){
ROS_INFO("Waiting for the move_base action server to come up");
}

ROS_INFO("Action server started, sending goal.");
// send a goal to the action
roadmap_global_planner_msgs::DoPatrolGoal goal;

ac.sendGoal(goal);

//wait for the action to return
bool finished_before_timeout = ac.waitForResult(ros::Duration(1.0));

if (finished_before_timeout)
{
actionlib::SimpleClientGoalState state = ac.getState();
ROS_INFO("Action finished: %s",state.toString().c_str());
}
else
ROS_INFO("Action did not finish before the time out.");

//exit
return 0;
}`

The program freezes at actionlib::SimpleActionClient<roadmap_global_planner_msgs::DoPatrolAction> ac("patrol_controller", true);

Same case for whichever client i create.

How do i solve this problem?

sorry, that was a mistake with roadmap_global_planner_msgs's CMakeLists.txt.
I did not add actionlib_msgs to catkin_package(CATKIN_DEPENDS ).
