QT_MAC_USE_COCOA is defined when Qt is built to use the Cocoa framework.

Q_WS_MAC is defined when the Mac OS X GUI is present.

Q_OS_DARWIN is defined when Qt detects you are on a Darwin-based system (including the Open Source version).

The follewing flags are helpful when you want to define Mac OS X specific code: Otherwise the result will be undefined because Qt's global initializers have not been called yet. If a library links against Qt and references globals in Qt (from global initializers in your own library), be sure to link your application against Qt before linking it against the library. Initialization OrderДyld(1) calls global static initializers in the order they are linked into your application. This is done by setting the -r flag in the. Then relocation information is stored in the output file, so that this file could be the subject of another ld run. If you want to build a new dynamic library combining the Qt 4 dynamic libraries, you need to introduce the ld -r flag. Note that the DYLD_LIBRARY_PATH environment variable will override these settings, and any other default paths, such as a lookup of dynamic libraries inside /usr/lib and similar default locations.

QMAKE_LFLAGS_SONAME = you can modify the install name using the install_name_tool(1) on the command line. The application will find a dynamic library if it has the install name you use qmake and Makefiles, use the QMAKE_LFLAGS_SONAME setting: 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 frameworksД«y 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'. (See also the document Qt is Mac OS X Native.)
