此页面描述了配置和构建的过程，针对 Qt for Android . To download and install a pre-built Qt for Android, follow the instructions on the Qt 快速入门 页面。
To build Qt for Android from source please ensure all requirements from Qt for Android 快速入门 are met before continuing.
Building Qt for Android on Windows also requires the following software:
注意： Qt for Android does not support building from source with Microsoft Visual C++ (MSVC).
Install the requirements, and set the
PATH
to include the newly installed binaries:
set MINGW_ROOT=<MINGW_ROOT_PATH>\bin set PATH=%MINGW_ROOT%;%PATH%
To verify the installation, run:
where mingw32-make.exe
The command should list mingw32-make.exe under the path <MINGW_ROOT> 首先。
You can download the Qt sources from the Qt Downloads page, or follow the wiki guide for Getting the source code .
Qt 6 allows building Qt for Android from source code using
CMake
. Qt 6 keeps the same configure script from Qt 5. The main difference is that Qt for Android is dependent on a host Qt build, which means to build Qt for Android, you need to build Qt for the desktop platform used as a host (for example Linux, macOS, or Windows).
To configure Qt for Android, create a shadow build directory to keep the source directory clean:
mkdir <path_to_build_dir>/build-qt cd <path_to_build_dir>/build-qt
And then run the configure script:
<path_to_qt_source>/configure -platform android-clang -prefix </path/to/install> -android-ndk $ANDROID_NDK_ROOT -android-sdk $ANDROID_SDK_ROOT -qt-host-path <path_to_host_qt_installation>
注意：
configure always uses the
Ninja
generator and build tool if a
ninja
executable is available. Ninja is cross-platform, feature-rich, performant, and recommended on all platforms. The use of other generators might work but is not officially supported.
Qt for Android supports the following ABIs:
此 Qt 发行支持下列配置：
| 分发 | 体系结构 | 编译器 | 注意事项 |
|---|---|---|---|
| Android 8.0 到 Android 13 (API 级别 26 到 API 33) |
armeabi-v7a
,
x86
,
arm64-v8
，和
x86_64
|
由 Google 提供的 Clang 14.0.6 (NDK r25b) | 对于 JDK 版本见 JDK (Java 开发工具包) |
注意：
It's recommended that Qt user apps use the same NDK r25b version used for building these official Qt for Android libraries. An NDK version more recent than r23b is required if building a project results in an error of missing the symbols for
__emutls_get_address
.
To choose the ABI to build for, use the -android-abis feature of the configure script.
注意： 6.5 does not yet support being built for multiple ABIs at the same time.
Qt for Android contains Java code which is compiled into *.jar files with javac . To set the javac version for source and target, use -android-javac-source and -android-javac-target respectively:
-android-javac-source 8 -android-javac-target 8
To build Qt as a developer build instead of a prefix build, use the following instead of
-prefix
自变量：
-developer-build
Qt 配置选项 contains more information about the configure options.
To build the configured Qt code, run the following command:
cmake --build . --parallel
Now, to install Qt, run the following command:
cmake --install .
On Unix based OSes you should prefix the install command with the
sudo
命令。
If you haven't provided the
--prefix <install-dir>
configure option, the installation is placed under
/usr/local/Qt-<version>
.
