Undefined Reference when OpenCV libraries cross compiled in Eclipse for Raspberry Pi - c++

Question

I am cross-compiling OpenCV libraries (2.4.9) and Raspicam (0.1.3) in Eclipse CDT IDE for Raspberry Pi. I am trying to compile a basic application that looks as the following:
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/opencv.hpp>
#include <raspicam.h>
#include <raspicam_cv.h>
using namespace std;
using namespace cv;
int main()
{
....
namedWindow(output_window_name, CV_WINDOW_AUTOSIZE);
namedWindow(grayscale_window_name, 100);
namedWindow(thresholded_window_name, 100);
namedWindow(contours_window_name, 100);
moveWindow(grayscale_window_name, 20,20);
moveWindow(thresholded_window_name, 20, 250);
moveWindow(contours_window_name, 20, 600);
vector<int> compression_params;
compression_params.push_back(CV_IMWRITE_JPEG_QUALITY);
compression_params.push_back(100);
raspicam::RaspiCam_Cv Camera;
....
}
To compile I made sure that libopencv_*.so files are in the cross compilation sysroot and linked in Eclipse using -l flags such as -lopencv_core -lopencv_highgui etc. I also included every include/ folder in sources using -I flag in Eclipse Build Settings.
Inclusion using #include and namespace declarations do not result in any errors.
Target building looks like this in the console:
arm-linux-gnueabihf-g++
-L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\lib"
-L"C:/SysGCC/Raspberry/arm-linux-gnueabihf/sysroot/usr/lib/arm-linux-gnueabihf"
-L"C:\rpi-eclipse\workspace\RaspberryTest\libbluetooth"
-L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\lib"
-Wl,-rpath-link,"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\lib\arm-linux-gnueabihf"
-o "RaspberryTest" ./src/<ALL OBJS>
-lwiringPi
-lopencv_calib3d
-lopencv_core
-lopencv_features2d
-lopencv_flann
-lopencv_highgui
-lopencv_imgproc
-lopencv_ml
-lopencv_objdetect
-lopencv_video
-lbluetooth
-lpthread
-lwiringPiDev
However, the following errors are there:

This indicates that I have two type of errors.
1-) undefined reference (for functions)
2-) undefined reference to vtable` (Related to virtual functions I believe)
In order to overcome this problem, I feel like I have to change STL/C standards, but do not know what to do exactly. Also, the fact that libraries are compiled and included correctly but there are still undefined references is really weird to me.
Any guidance regarding how to solve this problem is greately appreciated.
Thanks in advance.
