    <p>I have a collection of projects that I'm compiling as dynamic libraries. Each of these .dylibs depend on other various .dylibs that I would like to place in various other directories (i.e. some at the executable path, some at the loader path, some at a fixed path).</p> <p>When I run <code>otool -L</code> on the compiled libraries, I get a list of paths to those dependencies but I have know idea how those paths are being set/determined. They almost appear pseudo random. I've spent hours messing with the "Build Settings" in Xcode to try and change these paths (w/ @rpath, @executable_path, @loader_path, etc.) but I can't seem to change anything (as checked by running <code>otool -L</code>). I'm not even entirely sure where to add these flags and don't really understand the difference between the following or how to properly use them:</p> <p>Linking - "Dynamic Library Install Name"<br> Linking - "Runpath Search Paths"<br> Linking - "Other Linking Flags"<br> Search Paths - "Library Search Paths"</p> <p>When I run <code>install_name_tool -change</code> on the various libraries, I am able to successfully change the run path search paths (again as verified by running <code>otool -L</code> to confirm).</p> <p>I'm running Xcode 4.2 and I'm very close to giving up and just using a post-build script that runs install_tool_name to make the changes. But its a kludge hack fix and I'd prefer not to do it.</p> <p>Where can I see how the search/run paths for the dylib dependencies are being set?<br> Anyone have any ideas on what I might be doing wrong?</p>

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.
