The application will find a dynamic library if it has the install name you use qmake and Makefiles, use the QMAKE_LFLAGS_SONAME setting: QMAKE_LFLAGS_SONAME = you can modify the install name using the install_name_tool(1) on the command line. If you want to use some dynamic libraries in your Mac OS X application bundle (the application directory), create a subdirectory named 'Frameworks' in the application bundle directory and place your dynamic libraries there. If you don't want to use frameworks, simply configure Qt with -no-framework. Instead, you can temporarily swap your debug and release versions, which is documented in Apple's 'Debugging Magic' technical note. This is often done by using the DYLD_IMAGE_SUFFIX environment variables, but that way often doesn't work so well. If you actually want to use a debug version of a Qt framework, you must ensure that your application actually loads that debug version. However, one point to remember is: Frameworks always link with 'release' versions of libraries. The Framework Programming Guide discusses issues to keep in mind when choosing frameworks over the more typical, dynamic libraries. In general, this shouldn't be an issue because qmake takes care of the specifics for you. See Apple's Framework Programming Guide for more information. There are definite advantages to using them. Frameworks is the Mac OS X 'preferred' way of distributing libraries. Library Support Qt libraries as frameworksīy default, Qt is built as a set of frameworks. Also it is impossible to paint outside of a paint event so Qt::WA_PaintOutsidePaintEvent has no effect either. Mac OS X always double buffers the screen so the Qt::WA_PaintOnScreen attribute has no effect.

Later versions allow you to pass the bundle name on the command line. If you are using older versions of GDB you must run with the full path to the executable.

GUI applications in particular must be run from a bundle or by using the open(1), because Mac OS X needs the bundle to dispatch events correctly, as well as for accessing the menu bar. A bundle is a directory structure that groups related files together (e.g., widgets.app/). Mac OS X handles most applications as 'bundles'.
