The easiest way to install them is probably via Fink, which is what I’m using (binary distribution, version 0.7.2 on Panther, 0.8.0 on Tiger). OpenCV depends on several tools and libraries. I have installed Apple’s X11 (can be found on the OS install CDs/DVD as X11User.pkg) and X11 SDK (comes with XCode as X11SDK.pkg).

MACPORTS INSTALL CV2 MAC OS X

My Mac currently runs Mac OS X “Tiger” 10.4.4 with XCode 2.2, but I’ve also tested these instructions with Mac OS X “Panther” with XCode 1.5. Updated list of required Fink packages according to Tom’s comment (thanks Tom!) First published Prerequisites Also, I added an item to the quirks section. I’ve added some detailed installation instructions for FFmpeg now in the prerequisites section. Turns out the installation of FFmpeg wasn’t quite as straightforward as I thought-I had to run through this process on a Mac that didn’t have any developer tools installed. The test binaries will now build as well, although two tests in cxcoretest fail for reasons unknown to me. (If you used my previous patch, remove libavcodec* and libavformat* from /usr/local/lib before trying the new version.) I’ve also updated the patched OpenCV source so that the installation involves one step less and the binaries are bound at load time (see the updated quirks section). The dynamic linker will now no longer complain that it cannot find them.

MACPORTS INSTALL CV2 PATCH

I’ve updated the patch for FFmpeg so that the libraries are named and installed in the correct way. I was going to recommend using the current CVS version of OpenCV which obviates the need for a patched distribution, but last I checked, there was a bug preventing it from compiling cleanly on OS X. I’ve added the need for X11 to the prerequisites section. I’m also using a newer version of Fink now on Panther, but that doesn’t really change anything. You can now check whether you have the current version by verifying that the files match the supplied MD5 checksums (if you’re using Safari, it will probably uncompress them for you, so there are separate checksums for the uncompressed files).

MACPORTS INSTALL CV2 UPDATE

I had to update the FFmpeg patch again, so be sure to download the new version (no need to recompile on Panther, though). The instructions now apply to Mac OS X “Tiger” as well (but have a look at the quirks section if you want to run the tests).

I’ve updated the quirks section with a hint about setting -bind_at_load in XCode and a recommendation to use GCC 3.3.

However, I urge you to update to 0.9.7 because it contains a lot of bug fixes and improvements. I’ve removed the download link for my patched distribution, but the file is still there. This article stays valid since you still need some special configuration flags on OS X, and the FFmpeg patch stays useful as well. This removes the need for a patched distribution because the Linux version works on Mac OS X.

I’ve updated the instructions to take that into account. With OpenCV 0.9.7, the tests don't get compiled by default.

Made a German translation of this article.

I don’t use “Panther” any more, but the instructions still apply.

MACPORTS INSTALL CV2 HOW TO

Added a “Quick Start” section explaining how to get one of the OpenCV samples running.

Just send an e-mail, especially if you want to hear back from me, or use the comments link at the bottom right of this article. I welcome all your feedback and corrections or requests for help. The description of the installation process assumes familiarity with using the command line in Terminal. I’ll describe quirks in using OpenCV on the Mac as I stumble upon them.

I’ll list the prerequisites, then explain how to compile and install OpenCV as well as a sample program to get you started. In this article, I hope to explain how I got it to work. Some time ago, I managed to compile Intel’s Open Computer Vision library on Mac OS X.
