roscpp ServiceClient to standalone nodelet

edit

Hi there, I hope my question is easy to answer. I'm trying to software trigger my ifm3d sensor using its service "Trigger" I have built this sample test code but the client always returns FALSE.

#include "ros/ros.h"
#include <cstdlib>
#include </include/ifm3d/camera_nodelet.h>

int main(int argc, char **argv)
{
    ros::init(argc, argv, "trigger_ifm3d");
    if (argc != 1)
    {
         ROS_INFO("usage: one args required, got %d", argc);
         return 1;
    }

    ros::NodeHandle n;
    ros::ServiceClient client = n.serviceClient<ifm3d::Trigger>("Trigger");
    ifm3d::Trigger srv;

    int res = client.call(srv);
    if (res)
    {
        ROS_INFO("Status: %ld", (long int)srv.response.status);
    }
    else
    {
        ROS_ERROR("Failed to call service ifm3d::Trigger");
        return 1;
    }

    return 0;
}

Note: my ifm3d include path is wrong, if I specify the full path from root it compiles, so there is something not quite right with my cmake file. I don't believe this is related to my service problem.

I can trigger camera using "rosservice call /ifm3d/camera/Trigger" command line command. So I know the camera is working and accepting triggers.

I think something is wrong with namespace or nodelet standalone thing. The source code for ifm3d is here on github ifm3d_ros

The code in camera_nodelet.h is way above my head and doesn't match the example shown here

any help appreciated, thanks.
