Qt 编译前自动执行和编译后自动执行脚本

引用：https://blog.csdn.net/wkr2005/article/details/93711321

qt的pro配置文件中也可添加各种编译前后的操作及配置，主要通过 QMAKE_POST_LINK和QMAKE_PRE_LINK；

QMAKE_POST_LINK表示编译后执行内容

QMAKE_PRE_LINK表示编译前执行内容

举例如下：

#-------------------------------------------------
#
# Project created by QtCreator 2020-11-13T10:30:08
#
#-------------------------------------------------

QT       -= gui

TARGET = ComuPCIe
TEMPLATE = lib

DEFINES += COMUPCIE_LIBRARY

# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0


DESTDIR += ../bin

SOURCES += \
        comupcie.cpp

HEADERS += \
        comupcie.h

unix {
    target.path = /usr/lib
    INSTALLS += target
}
win32 {
    binDstPath = C:/radsim/bin
    libDstPath = C:/radsim/lib
    headerDstPath = "C:\\radsim\\include\\"
    libSrcName = $$DESTDIR/*.lib
    binSrcName = $$DESTDIR/*.dll
    headerSrcName = $$PWD/comupcie.h
    exists($$headerSrcName){
        message($$headerSrcName)
        message($$headerDstPath)
        message($$replace(headerSrcName, /, \\))
    }
    QMAKE_POST_LINK += copy /Y $$replace(headerSrcName, /, \\) $$headerDstPath
}

就是说， QMAKE_POST_LINK 后面可以追加要执行的命令，这些命令必须可以再命令行运行，当然，这就运行你写脚本了。

补充：

在windows系统下面，由于命令行中大部分命令不支持“/”，所以把“/”替换成“\”。

 

多条命令语句之间可以用&&隔开，自动连续执行；

 

定义的宏变量，在非首位置使用时，需要带{}， 如

 

<span style="display: inline-block; position: relative; width: 3.125em; height: 0px; font-size: 120%;"><span style="position: absolute; clip: rect(1.385em, 1003.07em, 2.698em, -1000em); top: -2.292em; left: 0em;"><span id="MathJax-Span-2" class="mrow"><span id="MathJax-Span-3" class="mi" style="font-family: MathJax_Math; font-style: italic;">P<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.109em;"><span id="MathJax-Span-4" class="mi" style="font-family: MathJax_Math; font-style: italic;">W<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.104em;"><span id="MathJax-Span-5" class="mi" style="font-family: MathJax_Math; font-style: italic;">D<span id="MathJax-Span-6" class="texatom"><span id="MathJax-Span-7" class="mrow"><span id="MathJax-Span-8" class="mo" style="font-family: MathJax_Main;">/

PWD/{DESTDIR}/$${TARGET}.dll中的DESTDIR和TARGET。
