Glibcxx error compiling FREAK OpenCV demo file - c++

Question

i have tried out this file to compile with
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/features2d/features2d.hpp>
#include <opencv2/nonfree/features2d.hpp>
#include <opencv2/legacy/legacy.hpp>
using namespace cv;
static void help( char** argv )
{
std::cout << "\nUsage: " << argv[0] << " [path/to/image1] [path/to/image2] \n"
<< "This is an example on how to use the keypoint descriptor presented in the following paper: \n"

// for OpenCV general detection/matching framework details
if( argc != 3 ) {
help(argv);
return -1;
}
// Load images
Mat imgA = imread(argv[1], CV_LOAD_IMAGE_GRAYSCALE );

Mat imgMatch;
drawMatches(imgA, keypointsA, imgB, keypointsB, matches, imgMatch);
namedWindow("matches", CV_WINDOW_KEEPRATIO);
imshow("matches", imgMatch);
waitKey(0);
}
with this command
gcc freak_demo.cpp `pkg-config opencv --cflags --libs`
and received this error message
/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: /tmp/ccwSmrle.o: undefined reference to symbol '_ZNSsD1Ev##GLIBCXX_3.4'

/usr/lib64/libstdc++.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
I don't know what GLIBCXX is. Which package (OpenSuse 13.1, gcc 4.8) do I have to install? I don't know how to interpret the error message, any help is appreciated.

As Daniel Frey said in his comment, use g++ instead of gcc. This solved the exact same problem for me, but for the compilation of a totally different program.
