I am using Opencv 3 Alpha on Ubuntu 14, everything works fine until I started using some macros... anything like CV_BGR2GRAY, CV_LOAD_IMAGE_GRAYSCALE; Have they got changed and where can I find them?

If you have not used the "using namespace cv" statement, you might have forgotten to use cv::CV_BGR2GRAY but remembered it for functions. That's one possibility that I could think of. – Cheeku Nov 01 '14 at 19:37

I think it is something related to OpenCv 3.0, I have used other macros like namedWindow("Display Image", WINDOW_NORMAL); and it works fine – Samer Nov 01 '14 at 19:40

From this forum post and this SO answer it looks like these values have changed in OpenCV 3 to COLOR_BGR2GRAY and cv::IMREAD_GRAYSCALE.
You can also try including legacy.hpp and see if that solves the missing definitions.

I was not able to include legacy.hpp, do you have any idea where is it located? – Samer Nov 01 '14 at 20:25
