Installing OpenCV on OSX 10.6 Using MacPorts

Question

I tried installing OpenCV in accordance with the MacPorts installation instructions at http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port by typing

sudo port install opencv

in the terminal.

The installs / compilations seem to be all right and the files are in the / opt / local subdirectories, as it should be. As a first test, I tried to include highgui.h in the C ++ source file:

#include <highgui.h>

but when compiling with g ++ or gcc I get error: highgui.h: No such file or directory. I'm new to Mac development, so maybe I missed something? It seemed to me that I needed to set some path variable, and after reading some of the messages that I found while searching on Google, I tried to set DYLD_LIBRARY_PATH = / opt / local / lib, but this was a wild assumption, and this did not seem to help . What can compilers find a library for?

Thank!
