Undefined reference to cv::Feature2D::compute

edit

Hi,

I am running ROS Hydro and OpenCV 2.4.7, using openFabMap and SURF. When I do catkin_make on my project, I get the following error:

undefined reference to `cv::Feature2D::compute(cv::Mat const&, std::vector<cv::KeyPoint, std::allocator<cv::KeyPoint> >&, cv::Mat&) const'

I noticed that this happens when I write the following line of code:

cv::SurfDescriptorExtractor extractor;
extractor.compute( cv_ptr->image, keypoints, descriptors_img);

UPDATE Other cv classes, such as the cv::SurfFeatureDetector detector class work normally. It even instantiates the cv::SurfDescriptorExtractor extractor with no problem. If I comment the "extractor.compute" call, I get no error.

I am including the following on the header:

#include <ros/ros.h>
#include <image_transport/image_transport.h>
#include <cv_bridge/cv_bridge.h>
#include <sensor_msgs/image_encodings.h>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/features2d/features2d.hpp>
#include <opencv2/nonfree/features2d.hpp>
#include <opencv2/nonfree/nonfree.hpp>
#include <opencv2/opencv.hpp>

UPDATE And my (complete this time) CMakeLists:

cmake_minimum_required(VERSION 2.8.3)

target_link_libraries(image_converter ${catkin_LIBRARIES})
target_link_libraries(image_converter ${OpenCV_LIBRARIES})

Am I missing some dependencies? I don't recall this error happening when building with earlier versions of OpenCV.

Thanks for your time and support.
