Running openCV 2.4.11 on eclipse (Ubuntu) - c++

Question

I'm a student from germany and for my bachelor thesis I am required to run a programm and later do something with the output it gives me. However, the programm is written by using openCV and I have a lot of trouble configuring openCV on my PC. I already followed a lot of tutorials and I have openCV 2.4.11 installed on my PC correctly (I think).
Now I tried to test my setup using the following code from one of the tutorials:
#include <cv.h>
#include <highgui.h>
using namespace cv;
int main( int argc, char** argv ) {
Mat image;
image = imread( argv[1], 1 );
if( argc != 2 || !image.data ) {
printf( "No image data \n" );
return -1;
}
namedWindow( "Display Image", CV_WINDOW_AUTOSIZE );
imshow( "Display Image", image );
waitKey(0);
return 0;
}
I properly told eclipse where my include files and lib files are and which of them to include. I don't get any errors in the code whatsovever.
But when I try and build my project, it won't work. Instead, I get an endless list of errors that lead to being unable to build it.
The errors read like (That's like 0.1 % of them):
templmatch.cpp:(.text._ZN2cv9crossCorrERKNS_3MatES2_RS0_NS_5Size_IiEEiNS_6Point_IiEEdi+0x1158): Nicht definierter Verweis auf `cv::dft(cv::_InputArray const&, cv::_OutputArray const&, int, int)'

I googled the "Nicht definierter Verweis" part and found out that it is the german version of "undefined reference". However the solutions offered there did not solve my problem. I had the same problem in windows as well as on a different computer before but people told me it was Window's fault and that I should use ubuntu and all my problems would be gone.
I'm sorry if this was answered before and I just missed it. However I'd really appreciate any help :)

Answer 1

Sorry, not enough reputation to comment, so answering:
Your undefined references are referencing functions (like dft) that are not being called in your code. You might be actually building something different than what you think.

Answer 2

In case it's helpful, here's a skeleton CMakeLists.txt file which will compile a opencv c++ file:
cmake_minimum_required(VERSION 2.8)
PROJECT(yourFileName)
FIND_PACKAGE(OpenCV REQUIRED)
ADD_EXECUTABLE(${PROJECT_NAME} yourfile.cxx)
TARGET_LINK_LIBRARIES(
${PROJECT_NAME}
${OpenCV_LIBS})
ADD_DEFINITIONS(-std=c++11)
If you run this directly through cmake either gui or command then it should work and then at least it will run so you can work out eclipse later..
