Hey all!
I am trying to do the camera calibration, because i need a calibration file in XML or YML format. I have read the official "Camera calibration with OpenCV" tutorial, link: link text I tried to run the code in terminal with the following command: "gcc camera_calibration.cpp" I also tried to run it with the Geany IDE, but I got the following errors:
g++ -Wall -o "camera_calibration" "camera_calibration.cpp" (in directory: /home/mirind4/DiplomaMSC/OpenCV/opencv-2.4.10/samples/cpp/tutorial_code/calib3d/camera_calibration)

To be honest, these errors are only about the 25% of total error messages, but I do not want to "spam" this post with them, because in my opinion the problem lies somewhere else....
