1. PreambleStarting today, start using your Mac to run OPENCV. Start feeling should actually develop resistance is not too big look, actually speaking, actually is more cumbersome than Windows. The current point configuration is OS X Yosemite 10.10.3 OpenCV 2.4.10 (The current point of the latest version is: 3.0 RC1) Xcode Version 6.3.2 (6d2105) In this configuration, I set up my

[OpenCV] building of openCV on Mac platform (Xcode + openCV 2.4.10) and opencvxcode1. Preface From today on, we started to use Mac to run openCV. At first, I felt that the development resistance was not too great. In fact, it was more complicated than Windows. The current time point is configured OS x yosemite 10.10.
