There are two ways to install Qt:
Below, you will find more information about building Qt from source.
Note: Qt 5 uses Cocoa, therefore, building for Carbon is not possible.
See Supported Platforms for the list of macOS versions supported by Qt.
Qt can be built for either x86_64 or x86_64h (Haswell). x86_64 is used by default. To select a x86_64h build, use the
qmake variable. This is selectable at configure
./configure -platform macx-clang QMAKE_APPLE_DEVICE_ARCHS=x86_64h
QMAKE_APPLE_DEVICE_ARCHS can also be specified as a space-delimited list in order to build for multiple architectures simultaneously:
./configure -platform macx-clang QMAKE_APPLE_DEVICE_ARCHS="x86_64 x86_64h"
Note: Qt 5.10+ does not support 32-bit builds.
Note: Qt 5 does not support OS X on PowerPC.
Note: Static builds are not tested.
On the command-line, applications can be built using
qmake can generate project files for Xcode with
-spec macx-xcode. If you are using the
qmake generates Xcode projects by default; use
-spec macx-gcc to generate makefiles. For example:
qmake -spec macx-xcode project.pro
-spec macx-xcode generates an Xcode project file from project.pro. With qmake you do not have to worry about rules for Qt's preprocessors (moc and uic) since qmake automatically handles them and ensures that everything necessary is linked into your application.
Qt does not entirely interact with the development environment (for example plugins to set a file to "mocable" from within the Xcode user interface).
The result of the build process is an application bundle, which is a directory structure that contains the actual application executable. The application can be launched by double-clicking it in Finder, or by referring
directly to its executable from the command line, for example,
If you wish to have a command-line tool that does not use the GUI for example,
ls, you can tell qmake to disable bundle creation from the
CONFIG variable in the
CONFIG -= app_bundle
In general, Qt supports building on one macOS version and deploying to earlier or later macOS versions. The recommended way is to build on the latest version and deploy to an earlier macOS version.
macOS applications are typically deployed as self-contained application bundles. The application bundle contains the application executable as well as dependencies such as the Qt libraries, plugins, translations and other resources you may need. Third party libraries like Qt are normally not installed system-wide; each application provides its own copy.
A common way to distribute applications is to provide a compressed disk image (.dmg file) that the user can mount in Finder. The deployment tool,
macdeployqt (available from the macOS installers), can be used to
create the self-contained bundles, and optionally also create a .dmg archive. Applications can also be distributed through the Mac App Store. Qt 5 aims to stay within the app store sandbox rules. macdeployqt (bin/macdeployqt)
can be used as a starting point for app store deployment.
The page below covers specific issues and recommendations for creating macOS applications.
We invite you to explore the rest of Qt. We prepared overviews to help you decide which APIs to use and our examples demonstrate how to use our API.
Qt's vibrant and active community site, http://qt.io houses a wiki, a forum, and additional learning guides and presentations.
