How to compile OpenCV 2.4.0 (beta2) by Cmake on Ma

Question

I want to use Opencv 2.4.0 (beta2) together with EmguCV and MonoDevelop on my Mac OS X Lion system. But I failed to compile the OpenCV 2.4.0 by Cmake and it shows lacking of some dylib files of highgui.

Anybody can tell me the whole configuration and process to compile OpenCV 2.4.0 in Mac OS X? Thanks.

Answer 1

To eliminate the error concerning the sphinx package for python, install it using

sudo easy_install -U Sphinx

OR if you use MacPorts:

sudo port install py26-sphinx

Before check the version of the default python interpreter "python --version". In my example it is 2.6.

Answer 2

I downloaded OpenCV 2.4.0 sources from the repository (rev 8301) and I had no problems compiling it on Mac OS X 10.7.3:

$ svn info
