    <p>Is there any specific reason why you want to statically link Qt+VTK+Boost with the app? On the Mac, for libraries like these I can't think of any reason (except licensing) why static linking would be preferable to dynamic. </p> <p>Take a look at the "Deploying an Application on Mac OS X" link that Bavarious posted. It explains how Mac apps are stored in bundles, allowing an app made up of many files to appear to the user as a single file. Libraries can also be stored in a bundle (along with their header files), in which case it's called a framework. Any needed frameworks can be stored inside the app bundle, making the app self-contained.</p> <p>Qt comes with a utility called <code>macdeployqt</code> which automatically copies the Qt frameworks (plus plugins) into the bundle, then fixes up the app binary (using <code>install_name_tool</code>) so the dynamic linker knows to look in the app bundle. You'll probably need to do this manually for VTK and Boost, which could be more complicated if they aren't built automatically as frameworks. They are popular libraries though, there should be guides on the Internet about deploying Mac apps with VTK/Boost.</p> <p>Also, I would not use MacPorts to install Qt for this purpose. The Qt binaries <a href="http://qt.nokia.com/downloads/qt-for-open-source-cpp-development-on-mac-os-x" rel="nofollow">available from Nokia</a> work just fine, and they are universal (built for both 32-bit and 64-bit, in case you need to target both).</p> <p>By the way, I'm not particularly a Windows guy, but I don't think throwing DLLs into System32 is a good way to deploy libraries on Windows. For a Qt app I made, we put the Qt DLLs (and mingw/gcc DLLs) into the same folder as the .exe, and it worked fine.</p>

    1. COWhy static: because I would rather waste 200MB of someone's disk space than deal with compatibility issues / runtime crashes. If the demo works well, they can assign an actual "software guy" to do this and leave me alone.

    2. COI guess I'm really looking for an equivalent to the "DLLs and exe in one folder" on the Mac, but even this has limitations I'm sure since the system has to provide the Cocoa GUI stuff.

    3. COThe Mac equivalent of "DLLs and exe in a folder" is to make an app, copy all the frameworks/dylibs into the bundle, then do the `install_name_tool` fixup so all the library dependencies are satisfied by the libraries in the bundle. If you use `qmake`, it will generate a .app bundle, then you run `macdeployqt` to copy in the Qt libraries. For VTK and Boost, you can probably copy the dylibs (maybe built by MacPorts) into the Frameworks folder, then do `install_name_tool` manually. Just be careful about i386 vs. x86_64 for your app and VTK/Boost.

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.
