    <p><strong>TL;DR</strong></p> <p>Objective-C app linked with static library that dynamic links Boost Filesystem. App can be run from output directory using Terminal, but trying to run from Xcode debugger or Finder gives error <code>dyld: Library not loaded: libboost_filesystem.dylib &lt;snip&gt; Reason: image not found</code>.</p> <p><strong>Problem</strong></p> <p>In my Xcode project I have a structure that looks like this:</p> <pre><code>MainProject (Objective-C) - static_lib_that_uses_filesystem (C++) </code></pre> <p>To get everything to link, I added libboost_system and libboost_filesystem dylibs to the "Link Binary with Libraries" build phase in MainProject.</p> <p>When I try to run the app from either Xcode or Finder I get:</p> <pre><code>sharedlibrary apply-load-rules all warning: Unable to read symbols for libboost_filesystem.dylib (file not found). warning: Unable to read symbols from "libboost_filesystem.dylib" (not yet mapped into memory). warning: Unable to read symbols for libboost_system.dylib (file not found). warning: Unable to read symbols from "libboost_system.dylib" (not yet mapped into memory). [Switching to process 43957 thread 0x0] dyld: Library not loaded: libboost_filesystem.dylib Referenced from: /Users/ssteele/Library/Developer/Xcode/DerivedData/MainProject-dqrhyuarllykslftblocjdzxlran/Build/Products/Debug/MainProject.app/Contents/MacOS/MainProject Reason: image not found </code></pre> <p>I added a build stage to copy the dylibs to the Frameworks directory in the bundle, this doesn't help. I changed this to copy them to the Executables directory which also didn't help.</p> <p>Having them in the Executables directory <em>does</em> allow me to run the app from Terminal.</p> <p>How can I get the app to find the dylibs when run from Finder/Xcode?</p> <p><strong>Background Info</strong></p> <p>I'm using Xcode 4.2 on Lion and currently targeting Lion only. I built my shared libraries for filesystem like this:</p> <pre><code>./b2 threading=multi macosx-version=10.7 --with-filesystem stage </code></pre> <p>This creates libboost_system.dylib, libboost_filesystem.dylib, and also .a equivalents in the stage/lib directory, I'm referencing them in the project directly from there.</p>

    2. COI'm wondering if that name should include an @ reference of some sort, like `@executable_path/libboost_filesystem.dylib`. I can't seem to make that happen though.

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.
