Error compiling private.hpp OpenCV 3.0.0-rc1 - c++

Question

I downloaded OpenCV 3.0.0-rc1 and build it using CMAKE-gui 3.2.2 using VS2012 Win64 compiler. Binaries and libraries got generated and I set it up with Qt 64 bit. All programs are working fine except when I try to use the feature cv::LineSegmentDetector it shows a compile error in private.hpp file. The error says
unexpected end-of-line
My code is as follows
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgcodecs/imgcodecs.hpp>
#include <opencv2/features2d/features2d.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/core/private.hpp>
#include <opencv2/core/utility.hpp>
using namespace std;
int main()
{
cv::Mat image = cv::imread("C:\\Users\\IMAGE\\Desktop\\PROJ\\SAMPLE.png");
cv::imshow("TEST",image);
cv::waitKey();
cv::LineSegmentDetector lsd;
return 0;
}
And on following the error I found the 2nd line of the following part of the code in private.hpp as error highlighted.
#ifdef HAVE_EIGEN
# if defined __GNUC__ && defined __APPLE__
# pragma GCC diagnostic ignored "-Wshadow"
# endif
# include <Eigen/Core>
# include "opencv2/core/eigen.hpp"
#endif
# if defined __GNUC__ && defined __APPLE__
Please let me know if I am doing some implementation mistake or some changes in the private.hpp can fix this error. I am using windows 8 64 bit.

oh, never try to use something, that is called "private", i guess...
#include <opencv2/opencv.hpp> // includes all others
#include <opencv2/core/utility.hpp> // getTickCount, etc.
int main()
{
// LineSegmentDetector is an abstract class, you can't create an
// instance on the stack, but need to use Ptr and factory:
cv::Ptr<cv::LineSegmentDetector> lsd = cv::createLineSegmentDetector();
return 0;
}
