Qt for Windows - Building from Source

This page describes the process of configuring and building Qt for Windows. To download and install a pre-built Qt for Windows, follow the instructions on the Getting Started with Qt page.
本页介绍了为Windows配置和构建Qt的过程。要下载并安装适用于Windows的预构建Qt，请按照“Qt入门”页面上的说明进行操作。

Step 1: Getting the Sources

Qt sources can be installed in the Qt Online Installer. Source packages are also available as Git repositories, as archives in the Qt Account (commercial users), and on download.qt.io (open-source users).

Qt源可以安装在Qt在线安装程序中。源码包也可作为存档在（商业用户）和（开源用户）中提供。

If you install the sources through the Qt Online Installer, they will be available in the Qt installation directory, for instance C:\Qt\6.5.3\Src.

如果您通过Qt在线安装程序安装源代码，它们将在Qt安装目录中可用，例如。C:\Qt\6.5.3\Src

If you downloaded the source archive, extract it to a directory of your choice, for instance C:\dev\Qt\src.

如果您下载了源存档，请将其解压缩到您选择的目录中，例如 。C:\dev\Qt\src

Note: The path to the source directory must not contain any spaces or Windows specific file system characters. The path should also be kept short. This avoids issues with too long file paths in the compilation phase.

注意： 源目录的路径不得包含任何空格或特定于 Windows 的文件系统字符。路径也应保持简短。这样可以避免在编译阶段出现文件路径过长的问题。

Step 2: Install Build Requirements

To build Qt from sources you need a build environment with a supported compiler and various build tools available:
要从源代码构建Qt，您需要一个具有支持的编译器和各种可用构建工具的构建环境：

Build Tools

The executables cmake.exe, ninja.exe, and python.exe must be available in your build environment. You achieve this by adding the respective directory to your PATH environment variable.

Compilers

The following compilers and configurations are supported in Qt 6.5:
Qt 6.5支持以下编译器和配置：

Note: Windows on ARM is only supported as a deployment target. Applications have to be cross-compiled from an x86-64 Windows machine and deployed to target.

仅支持ARM上的Windows作为部署目标。应用程序必须从x86-64 Windows机器交叉编译，并部署到目标。

QDoc Dependencies

QDoc uses Clang to parse C++ code. If you wish to build QDoc manually, refer to Installing Clang for QDoc for specific build requirements.

QDoc使用Clang来解析C++代码。如果您希望手动构建QDoc，请参阅Installing Clang for QDoc以了解特定的构建需求。

Step 3: Set the Environment Variables

We recommend creating a desktop link that opens a command prompt with the environment set up similar to the Command Prompt menu entries provided by Visual Studio. This is done by creating an application link passing a .cmd file setting up the environment and the command line option /k (remain open) to cmd.exe.

我们建议创建一个桌面链接，该链接打开命令提示符，其环境设置类似于 Visual Studio 提供的菜单项。这是通过创建一个应用程序链接来完成的，该链接将设置环境和命令行选项（保持打开状态）的文件传递给cmd 。

Assuming the file is called qt6vars.cmd and the Qt folder is called C:\Qt\6.5.3\Src:

假设文件被调用并且Qt文件夹被调用：qt6vars.cmdC:\Qt\6.5.3\Src

REM Set up compiler, in this case Visual Studio Professional 2022 for amd64 CPU's
CALL "C:\\Program Files\\Microsoft Visual Studio\\2022\\Professional\\VC\\Auxiliary\\Build\\vcvarsall.bat" amd64
SET _ROOT=C:\\Qt\\6.5.3\\Src
SET PATH=%\_ROOT%;%PATH%
SET _ROOT=

A desktop link can then be created by specifying the command %SystemRoot%\system32\cmd.exe /E:ON /V:ON /k C:\Qt\qt6vars.cmd as application.

然后，可以通过将命令指定为应用程序来创建桌面链接。

Depending on your individual setup, you might also need to make the installation directories of CMake, Ninja, and Python part of the SET %PATH% line above.

根据您的个人设置，您可能还需要将 CMake、Ninja 和 Python 的安装目录作为上述行的一部分。SET %PATH%

Note: Setups for MinGW are similar; they differ only in that the bin folder of the installation should be added to the path instead of calling the Visual Studio setup script. For MinGW, please make sure that no sh.exe can be found in the path, as it affects mingw32-make.

注意: MinGW的设置类似;它们的区别仅在于应将安装文件夹添加到路径中，而不是调用 Visual Studio 安装脚本。对于 MinGW，请确保在路径中找不到 no，因为它会影响 。

Step 4: Build the Qt Library

To configure the Qt library for your machine type, create a build directory and change to this directory. Then call the configure.bat script. Alternatively, if you have already completed Step 3, you may double-click on the desktop link you created, change to the build directory, type configure and start configuring the Qt library.

要为您的机器类型配置 Qt 库，请创建一个构建目录并切换到此目录。然后调用脚本。或者，如果您已经完成了步骤3，则可以双击您创建的桌面链接，切换到构建目录，键入并开始配置Qt库。configure.batconfigure

Note: Add the Qt build directory to the list of excluded directories of any anti-virus application that runs on your system.

注意： 将Qt构建目录添加到系统上运行的任何防病毒应用程序的排除目录列表中。

mkdir qt6-build
cd qt6-build
C:\\Qt\\6.5.3\\Src\\configure.bat
cmake --build .
cmake --install .

By default, Qt is configured for installation in the C:\Program Files\Qt directory, but this can be changed by using the -prefix option.

默认情况下，Qt 配置为在目录中安装，但可以使用该选项-prefix进行更改。

The Configure Options page contains more information about the configure options. See Qt for Windows - Graphics Acceleration for specific options regarding graphics acceleration.
该页面包含有关配置选项的详细信息。有关图形加速的特定选项，请参阅。

configure-options

Qt 配置选项运行$ ./qt62/configure --help > ./123.txt可以查看配置选项。

Usage:  configure [options] [-- cmake-options]

This is a convenience script for configuring Qt with CMake.
Options after the double dash are directly passed to CMake.

Top-level installation directories:
  -prefix <dir> ...... The deployment directory, as seen on the target device.
                       [/usr/local/Qt-$QT_VERSION; qtbase build directory if
                       -developer-build]
  -no-prefix ......... The deployment directory is set to the qtbase build
                       directory. Can be used instead of -developer-build
                       to not have to install, as well as avoid
                       -developer-build's default of -warnings-are-errors.
  -extprefix <dir> ... The installation directory, as seen on the host machine.
                       [SYSROOT/PREFIX]

Fine tuning of installation directory layout. Note that all directories
except -sysconfdir should be located under -prefix:

  -bindir <dir> ......... Executables [PREFIX/bin]
  -headerdir <dir> ...... Header files [PREFIX/include]
  -libdir <dir> ......... Libraries [PREFIX/lib]
  -archdatadir <dir> .... Arch-dependent data [PREFIX]
  -plugindir <dir> ...... Plugins [ARCHDATADIR/plugins]
  -libexecdir <dir> ..... Helper programs [ARCHDATADIR/bin on Windows,
                          ARCHDATADIR/libexec otherwise]
  -qmldir <dir> ......... QML imports [ARCHDATADIR/qml]
  -datadir <dir> ........ Arch-independent data [PREFIX]
  -docdir <dir> ......... Documentation [DATADIR/doc]
  -translationdir <dir> . Translations [DATADIR/translations]
  -sysconfdir <dir> ..... Settings used by Qt programs [PREFIX/etc/xdg]
  -examplesdir <dir> .... Examples [PREFIX/examples]
  -testsdir <dir> ....... Tests [PREFIX/tests]
  -hostdatadir <dir> .... Data used by qmake [PREFIX]

Conventions for the remaining options: When an option's description is
followed by a list of values in brackets, the interpretation is as follows:
'yes' represents the bare option; all other values are possible prefixes to
the option, e.g., -no-gui. Alternatively, the value can be assigned, e.g.,
--gui=yes. Values are listed in the order they are tried if not specified;
'auto' is a shorthand for 'yes/no'. Solitary 'yes' and 'no' represent binary
options without auto-detection.

Configure meta:

  -help, -h ............ Display this help screen
  -redo ................ Re-configure with previously used options.
                         Additional options may be passed, but will not be
                         saved for later use by -redo.

  -feature-<feature> ... Enable <feature>
  -no-feature-<feature>  Disable <feature> [none]

cmd命令帮助

cmd /?
C:\Users\eric>cmd /?
启动 Windows 命令解释器的一个新实例

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
    [[/S] [/C | /K] string]

/C      执行字符串指定的命令然后终止
/K      执行字符串指定的命令但保留
/S      修改 /C 或 /K 之后的字符串处理(见下)
/Q      关闭回显
/D      禁止从注册表执行 AutoRun 命令(见下)
/A      使向管道或文件的内部命令输出成为 ANSI
/U      使向管道或文件的内部命令输出成为
        Unicode
/T:fg   设置前台/背景颜色(详细信息见 COLOR /?)
/E:ON   启用命令扩展(见下)
/E:OFF  禁用命令扩展(见下)
/F:ON   启用文件和目录名完成字符(见下)
/F:OFF  禁用文件和目录名完成字符(见下)
/V:ON   使用 ! 作为分隔符启用延迟的环境变量
        扩展。例如，/V:ON 会允许 !var! 在执行时
        扩展变量 var。var 语法会在输入时
        扩展变量，这与在一个 FOR
        循环内不同。
/V:OFF  禁用延迟的环境扩展。

ninja命令帮助

–version # 打印版本信息
-v # 显示构建中的所有命令行（这个对实际构建的命令核对非常有用）
-C DIR # 在执行操作之前，切换到DIR目录
-f FILE # 制定FILE为构建输入文件。默认文件为当前目录下的build.ninja。如 ./ninja -f demo.ninja
-j N # 并行执行 N 个作业。默认N=3（需要对应的CPU支持）。如 ./ninja -j 2 all
-k N # 持续构建直到N个作业失败为止。默认N=1
-l N # 如果平均负载大于N，不启动新的作业
-n # 排练（dry run）(不执行命令，视其成功执行。如 ./ninja -n -t clean)
-d MODE # 开启调试模式 (用 -d list 罗列所有的模式)
-t TOOL # 执行一个子工具(用 -t list 罗列所有子命令工具)。如 ./ninja -t query all
-w FLAG # 控制告警级别

QT运行时的Debug、Release、Profile选项区别

根据官方说明，profile则是在这两种之中取一个平衡，兼顾性能和调试，可以类似的看做是性能更优但是又方便调试的版本
使用Qt5.7版本对应三种模式编译的空白窗体程序大小：debug（1319kb）、release（24kb）、profile（90kb）

MSVC编译器的选择(x86，amd64_x86，amd64，x86_amd64)

• x86：编译器为x86版本，输出文件为x86。
• amd64_x86：编译器为amd64版本，输出文件为x86。
• amd64：编译器为amd64版本，输出文件为amd64。
• x86_amd64：编译器为x86版本，输出文件为amd64。
