Hi thank you for your reply.

You're right, i had only ar_pose in my workspace. Now my workspace looks like src/ar_tools/ar_pose, artoolkit, artools and rosdep.yaml. Wenn i try to creat ar_tools, i still get the same error. Have tried all day.

This is what i get: Linking CXX executable /home/benjamin/workspace_ck/devel/lib/ar_pose/ar_single

Hi there, i try to compile ar_pose on ros indigo. I get always the same problem:

CMakeFiles/ar_single.dir/src/ar_single.cpp.o: In Funktion ar_pose::ARSinglePublisher::getTransformationCallback(boost::shared_ptr<sensor_msgs::Image_<std::allocator<void> > const> const&)': /home/benjamin/workspace_ck/src/ar_pose/src/ar_single.cpp:215: Nicht definierter Verweis auf_IplImage::_IplImage(cv::Mat const&)' collect2: error: ld returned 1 exit status

ar_single.cpp:

void ARSinglePublisher::arInit () 
{  
    ...
    cv_bridge::CvImagePtr capture_;
    ...
}
  void ARSinglePublisher::getTransformationCallback (const sensor_msgs::ImageConstPtr & image_msg)
  {
    ARUint8 *dataPtr;
    ARMarkerInfo *marker_info;
    int marker_num;
    int i, k;

    /* Get the image from ROSTOPIC
     * NOTE: the dataPtr format is BGR because the ARToolKit library was
     * build with V4L, dataPtr format change according to the 
     * ARToolKit configure option (see config.h).*/
#if ROS_VERSION_MINIMUM(1, 9, 0)
    try
    {
      capture_ = cv_bridge::toCvCopy (image_msg, sensor_msgs::image_encodings::BGR8);
    }
    catch (cv_bridge::Exception& e)
    {
      ROS_ERROR("cv_bridge exception: %s", e.what());
    }

    //cvNamedWindow("MyWindow", CV_WINDOW_AUTOSIZE); // does opencv works? - yes


    //dataPtr = (ARUint8 *) ((IplImage) capture_->image).imageData;

    dataPtr = (ARUint8 *) ((IplImage) capture_->image).imageData;
...

Can someone help me ?

When I try to built ar_pose i get always the same error, also in the ar_multi.cpp.
