Building Qt Creator projects from command line
提问by Tamás Szelei
I'm in the process of writing a build script to automate build and release tasks. I have a Qt Creator project which has three configurations, two of which I want to completely rebuild from scratch without any precompiled headers and existing .o files to skip (release and release_production). The latter is the same except it has the PRODUCTION symbol #defined.
我正在编写构建脚本来自动化构建和发布任务。我有一个 Qt Creator 项目，它有三个配置，其中两个我想从头开始完全重建，没有任何预编译的头文件和现有的 .o 文件要跳过（release 和 release_production）。后者是相同的，只是它有生产符号#defined。
I'm using windows. How can I build these configurations from the command line?
我正在使用窗户。如何从命令行构建这些配置？
Edit: Some clarification: The Qt Creator custom build steps are not stored in the qmake makefile but in the Qt Creator-specific .pro.user XML file. I would like to perform these from the command line without repeating them in the script.
编辑：一些说明：Qt Creator 自定义构建步骤未存储在 qmake 生成文件中，而是存储在 Qt Creator 特定的 .pro.user XML 文件中。我想从命令行执行这些而不在脚本中重复它们。

There are two steps involved here:
这里涉及两个步骤：
Running
qmaketo generate Makefiles. The usual command isc:\qt.7.2\bin\qmake.exe" path\to\some\project.pro -r -spec win32-g++ CONFIG+=...The
-specswitch is important. Make sure you supply a valid makespec file.CONFIGneeds to be specified in this step.Running
maketo compile and link. This is easyC:\MinGW32\bin\mingw32-make -f Makefile.DebugRemember to point
maketo the correct makefile.
运行
qmake以生成 Makefile。通常的命令是c:\qt.7.2\bin\qmake.exe" path\to\some\project.pro -r -spec win32-g++ CONFIG+=...该
-spec开关是非常重要的。确保提供有效的 makespec 文件。CONFIG这一步需要指定。运行
make编译和链接。这很简单C:\MinGW32\bin\mingw32-make -f Makefile.Debug请记住指向
make正确的makefile。

In the project tab of QtCreator you have the exact command, QtCreator runs on build for both debug and release. Just run those lines in a environment your project can be build (Qt console). But basically Qt projects are build with a qmake.exethen a nmake.exeor the Qt multi-thread make-like executable jom.exe.
在 QtCreator 的项目选项卡中，您有确切的命令，QtCreator 在构建时运行，用于调试和发布。只需在可以构建项目的环境中运行这些行（Qt 控制台）。但基本上 Qt 项目是使用qmake.exethen anmake.exe或 Qt multi-thread make-like executable 构建的jom.exe。
For your "production" mode your can use CONFIG+=productionargument in the qmake command, then in your .pro files :
对于您的“生产”模式，您可以CONFIG+=production在 qmake 命令中使用参数，然后在您的 .pro 文件中使用：
CONFIG(production){
DEFINES+=PRODUCTION
}else{
}
