I am running Mountain Lion, Xcode 4.4.1, and downloaded Open CV 2.4.2. Like you, I found the task of getting all the pieces in the right place in the right order pretty daunting. IвЂ™m a iPhone/Mac OS X GUI programmer so the Terminal and low level stuff is new to me. IвЂ™ve been reading Learning OpenCV and wanting to start writing code.

Feel free to comment if you donвЂ™t find an answer.

If you have questions, skim through the comments because many people have posted their solutions. Unfortunately, itвЂ™s been a long time since I looked into OpenCV so I donвЂ™t remember the details anymore. Please read before commenting: Hey guys вЂ“ thanks a lot for all the comments on this thread. On that note, here is a good OpenCV Tutorial.Д®dit: Oops,В looks like that link is dead now. Hopefully, this helps save you some time. If itвЂ™s not, leave a comment below with the error you get and IвЂ™ll try looking into it for you. Remember to free image memory after using it!ДЄnd there you go.

Example showing how to read and write images This is where the header files for OpenCV were built.

Change the path to /usr/local/include.

Click on the project file and go to вЂњBuild SettingsвЂќ.

Feel free to move them to a separate group within your project. If you know what you need, you can obviously pick and choose. To prevent linker errors, I recommend you initially add ALL the files ending in вЂњвЂ¦2.3.1.dylibвЂќ.

When Finder pops up, hit вЂњ/вЂќ to bring up the navigation panel.

To do this, right click on the project, and click вЂњAdd files to.вЂќ dylib files provided by OpenCV into our project.

Start a new XCode Command Line Tool project.

So we now have OpenCV built but we still have to link to the framework in our project. This should now build OpenCV into your /usr/local/ directory. Type in the following: # make a separate directory for building In terminal, navigate to the folder where OpenCV was extracted to. We are going to build OpenCV using cmake. You can check to see that cmake is installed by typing cmake in a new terminal window.

This will go fetch cmake and its dependencies and install them onto your system.

Unzip it after you download it into a folder. You can check to see if it installed successfully by opening your terminal and typing port. Also you will need XCode installed for any of this to work (but you knew that, right?) Also, I tested this on OSX Lion, but it should apply to Snow Leopard or Leopard. Note: This method does not set up the Python bindings for OpenCV (still working on that). Now that IвЂ™ve got it set up, I decided to write this little post to explain to others how to go about setting it up. There are various ways to install it вЂ“ through package managers such as Homebrew or Macports, or through the tarball + cmake. I had to look through a whole bunch of different sites to figure out what to do. IвЂ™m using OpenCV for my 4th year design project and setting it up was a huge pain.
