Window-安装qt-MVSC2013编译器

首先安装VS2013：

vs2013.5_pro_chs.iso

 

然后安装qt

这里我们先随便选一个版本：

http://download.qt.io/archive/qt/5.13/5.13.2/

因为这个版本不一定有MVSC2013版本，或者你直接下载一个有MSVC2013的：

qt-opensource-windows-x86-msvc2013_64-5.8.0.exe(强烈建议直接安装这个)

 

但是我选择了没有MVSC2013版本的，练习一下步骤

这是别人的图，我当时只选择安装了红箭头指向的

 

然后找到安装路径下的：

MaintenanceTool.exe

 

选择设置：

 

清华大学的开源镜像站

https://mirrors.tuna.tsinghua.edu.cn/qt/online/qt5/windows/x86/online_repository/

 

红色箭头是原本安装的，红色圈出的是刚刚选择的：

然后会下载圈出的那部分进行安装

 

这里其实和直接安装qt-opensource-windows-x86-msvc2013_64-5.8.0.exe

效果一样，但是为了学习一下才这么折腾下

 

正在下载和安装MSVC2013

 

1.找不到opencv的头文件，或者库文件Qt编译出错Error in " Util.asciify("build-helloworld-Desktop_Qt_5_6_1_MinGW_32bit-Debug")

我的pro如下:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked 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 it uses 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

这个问题是我们配置qt的问题：

原本是

要改为自己的路径：

 

2.解决 Qt5 报错 This application failed to start because it could not find or load the Qt platform plugin

因为换了一个qt版本，之前的这些用不了，要用现在的，但是你也不知道要用那些，那么直接使用工具

QT为了简化生成发布版本，特别提供了工具 "windeplayqt.exe"，这个工具在 "...\Qt5.8.0\5.8\msvc2015_64\bin"的目录下，通过该命令，可以解决上述错误。

 

windeplayqt.exe D:\code\qt\twocameras_fixed_updated-libs_included\build\debug\sample.exe

windeplayqt.exe D:\code\qt\twocameras_fixed_updated-libs_included\build\release\sample.exe
