首先安裝VS2013：

vs2013.5_pro_chs.iso

 

然後安裝qt

這裏我們先隨便選一個版本：

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

因爲這個版本不一定有MVSC2013版本，或者你直接下載一個有MSVC2013的：

qt-opensource-windows-x86-msvc2013_64-5.8.0.exe(強烈建議直接安裝這個)

 

但是我選擇了沒有MVSC2013版本的，練習一下步驟

這是別人的圖，我當時只選擇安裝了紅箭頭指向的

 

然後找到安裝路徑下的：

MaintenanceTool.exe

 

選擇設置：

 

清華大學的開源鏡像站

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

 

紅色箭頭是原本安裝的，紅色圈出的是剛剛選擇的：

然後會下載圈出的那部分進行安裝

 

這裏其實和直接安裝qt-opensource-windows-x86-msvc2013_64-5.8.0.exe

效果一樣，但是爲了學習一下才這麼折騰下

 

正在下載和安裝MSVC2013

 

1.找不到opencv的頭文件，或者庫文件Qt編譯出錯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

這個問題是我們配置qt的問題：

原本是

要改爲自己的路徑：

 

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

因爲換了一個qt版本，之前的這些用不了，要用現在的，但是你也不知道要用那些，那麼直接使用工具

QT爲了簡化生成發佈版本，特別提供了工具 "windeplayqt.exe"，這個工具在 "...\Qt5.8.0\5.8\msvc2015_64\bin"的目錄下，通過該命令，可以解決上述錯誤。

 

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
