如何在qmake/qtcreator中添加预构建步骤? [英] How to add pre-build step in qmake/qtcreator?

问题描述

我希望编译后的应用程序具有提交号，源文件校验和以及其他在编译过程中可用的东西.

I want the compiled application to have the commit number, source files checksums and other things to be available during the compilation.

在普通的Makefile中，我喜欢这样:

In plain Makefiles I do like this:

prog: VERSION source.c
    gcc -DVERSION=\"$(shell cat VERSION)\" source.c -o prog 

VERSION: .git
    git describe > VERSION

如何在qmake中使用类似的东西?

推荐答案

如果将版本信息作为包含文件(例如"version.h")而不是#define传递，则可以添加以下内容到您的qmake文件中

If you were to pass the version information as an included file (let's say "version.h") instead of a #define, then you could add the following to your qmake file

# Define how to create version.h
version.target = version.h
version.commands = <PUT_YOUR_COMMANDS_HERE>
version.depends = .git

QMAKE_EXTRA_TARGETS += version

PRE_TARGETDEPS += version.h

前三行介绍了如何创建一个新的目标对象，该目标对象称为"version"，该对象将生成"version.h".通过执行命令< PUT_YOUR_COMMANDS_HERE>"来完成.目标取决于".git"

The first 3 lines tell how to make a new target object called "version" that generates "version.h". It is made by executing the commands "<PUT_YOUR_COMMANDS_HERE>". The target is dependent on ".git"

"QMAKE_EXTRA_TARGETS"表示存在一个称为版本"的新目标.

The "QMAKE_EXTRA_TARGETS" says there is a new target known as "version".

"PRE_TARGETDEPS"表示"version.h"必须存在，然后才能执行其他任何操作(如果尚未创建，则将其强制创建).

The "PRE_TARGETDEPS" indicates that "version.h" needs to exist before anything else can be done (which forces it to be made if it isn't already made).
