    <p>This stuff is always hard to figure out in the beginning. </p> <p>You don't need to copy the frameworks into the Frameworks directory because your project is a command line app. You only have an app bundle when you make a Cocoa app. And even in that case you only need to copy the frameworks into the Frameworks directory if you are going to distribute the app to people who don't have OpenCV installed.</p> <blockquote> <p>Note that this is despite the fact that libopencv_core.2.3.dylib is included in the same directory as the executable.</p> </blockquote> <p>Don't copy the library files into your executable file's folder. Just let it link to the files in /opt/local/lib</p> <p>I downloaded your project and was able to get it to run. Here's what I did (using Xcode 4):</p> <ol> <li>Delete the dylib files (and links) from the Edge Display folder</li> <li>Delete the Copy Files build phase that copies the library files</li> <li>Delete the <code>@executable_path/../Frameworks</code> Installation Directory setting</li> <li>Delete everything from the <code>OpenCV Frameworks</code> folder in the Xcode project</li> <li>Select the target, select Build Phases, expand <code>Link Binary With Libraries</code></li> <li>Click the plus button, click Add Other…, type "/opt/local/lib", select <code>libopencv_core.dylib</code> (note I didn't select a file with a version number)</li> <li>Repeat for <code>libopencv_highgui.dylib</code> and <code>libopencv_imgproc.dylib</code> (those are the only libraries your project needs)</li> <li>Set the Deployment Target to OS X 10.6 because that's what I'm using</li> <li>Click Run and get this:</li> </ol> <p><img src="https://i.stack.imgur.com/Fln6c.png" alt="My beautiful edge-detected face"></p> <p>My system is a little different than yours because my OpenCV libraries are installed in /usr/local/lib, but you already have /opt/local/include in the project's Header Search Path so you should be fine.</p> <p>There are some instructions for using the OpenCV libraries in an OS X command-line project on <a href="http://opencv.willowgarage.com/wiki/UsingOpenCVUnderOSX" rel="nofollow noreferrer">the OpenCV Wiki</a> but they're written for Xcode 3. I'll try to add some updated instructions for Xcode 4.</p>

    1. COThanks a lot for your help! Correct me if I'm wrong, but if I add libraries from /opt/local/lib and then distribute the executable to someone without OpenCV installed there, won't it throw an error on being unable to find those libraries? Where's the setting located for directing it to look in the executable's directory or any other arbitrary directory? Thanks!

    2. COYes. You are correct. But you have to make a distinction between command-line apps and Cocoa apps. With a Cocoa app you can embed the dylibs. You have to tell the application where to look for the libraries and you also have to tell the libraries where to look for themselves. [Details here.](http://stackoverflow.com/questions/7117128/xcode-dylib-looking-in-usr-lib/7170620#7170620). With a command-line app I believe you have to build and embed a static library the way you do with an iPhone program, but I haven't done that so I don't know the details.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
