Building Qt requires a macOS platform SDK and corresponding toolchain to be installed on the system. You can get this by installing the Xcode, as described in Qt for macOS#Build Environment .
You should always use the exact same Xcode and SDK version as listed in the Qt for macOS#Supported Versions , to ensure that Qt has been tested in the configuration you're building.
QDoc uses Clang to parse C++ code. If you wish to build QDoc manually, refer to 为 QDoc 安装 Clang 对于特定构建要求。
The following instructions describe how to build Qt from the source package. You can download the Qt sources from the 下载 页面。更多信息，拜访 Qt 快速入门 页面。
Unpack the archive if you have not done so already. For example, if you have the
qt-everywhere-opensource-src-%VERSION%.tar.gz
package, type the following commands at a command line prompt:
cd /tmp gunzip qt-everywhere-opensource-src-%VERSION%.tar.gz # uncompress the archive tar xvf qt-everywhere-opensource-src-%VERSION%.tar # unpack it
This creates the directory
/tmp/qt-everywhere-opensource-src-%VERSION%
containing the files from the archive.
To configure the Qt library for your machine type, run the
./configure
script in the package directory.
cd /tmp/qt-everywhere-opensource-src-%VERSION% ./configure
By default, Qt is configured for installation in the
/usr/local/Qt-%VERSION%
directory, but this can be changed by using the
-prefix
选项。
By default, Qt is built as a framework, but you can built it as a set of dynamic libraries (dylibs) by specifying the
-no-framework
选项。
As described in
Qt for macOS#Architectures
, Qt will build for the architecture of your development machine by default. To configure a universal build of Qt with support for both
x86_64
and
arm64
, add the following argument:
./configure -- -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64"
Qt can also be configured to be built with debugging symbols. This process is described in detail in the 调试技术 文档。
配置选项 页面包含有关 configure 选项的更多信息。
To create the library and compile all the examples and tools, type:
cmake --build . --parallel
若
-prefix
is outside the build directory, you need to install the library, examples, and tools in the appropriate place. To do this, type:
cmake --install .
This command requires that you have administrator access on your machine.
In order to use Qt, some environment variables need to be extended.
PATH - to locate qmake, moc and other Qt tools
This is done like this:
在
.profile
(if your shell is bash), or
.zshenv
(for zsh) add the following lines:
PATH=/usr/local/Qt-%VERSION%/bin:$PATH export PATH
在
.login
(in case your shell is csh or tcsh), add the following line:
setenv PATH /usr/local/Qt-%VERSION%/bin:$PATH
If you use a different shell, please modify your environment variables accordingly.
Qt is now installed.
