Qt Creator Download and install of  

One 、Qt and Qt Creator The difference between

Qt yes C++ A library , Or development framework , It integrates some library functions , Improve development efficiency .

Qt Creator It's a IDE, It's a platform , A development environment , Similar things like VS, It can also be done Qt Development , Of course VS Medium Qt It's inserted as a plug-in VS Platform .

Two 、 download

qtcreator yes Qt Developed IDE, You can't just install this , Because there's no relevant Qt The library? , That is to say, he is just an empty shell , You don't usually use .

qt The version of is mainly divided into windows、linux、mac Version of , Running on different platforms . stay qt5.9 before ,windows The version subdivides some versions , Include MinGW and MSVC. among MSVC With VS compiler , Some more need to be installed Visual C++ The library or something , All in all , If you don't have VS Then don't install this version , Otherwise, compilation will not work .

And what we're going to use is MinGW edition , Note that this compiler is only 32 Bit , So I'm looking for it 64 Don't look for a classmate who is a student . Some are for Android Development , I don't understand , But it doesn't work , As for what compiler GCC,G++ And so on. , I don't know much about ,MinGW It seems to be based on G++ Of .

And then say qt5.9 Later versions , In fact, it's integrated . Integrate some of the previous versions into one installation package , You can see the installation package from the previous 1.2G Change into 2.3G. And the specific subdivision is optional during installation , Like before MinGW and MSVC You can choose from different versions at installation time , and windows All versions are integrated into  qt-opensource-windows-x86-5.9.0  in .

4、 About   Qt 5.15 after , The problem of no longer providing a stand-alone installation package

If you choose the latest version of QT, There may not be a similar file to download  qt-opensource-windows-x86-5.14.2.exe. Such as 2020.8.16 when , The image already has 5.15 The catalog of , But there's no such thing in it .exe Installation file .

The reason is from Qt 5.15 Start , Open source version , Whether or not LTS, The compiled independent installation package is no longer available , It can only be installed online .

Online installation file download address ：

Finished compiling Qt, It's the last step —— How in your IDE Use in Qt5.15.

Qt Creator It's right there “ Options ” Just add a new build suite to ,VS2019（ Of course, you have to install it first QtTools For VS2019 Plug in for ） It's directly in QtTools Choose from qmake The path you are in can be （ Note that just select bin A higher level of , It will add after the path you give \bin\qmake.exe To search for ）.

（2） After compiling, the project is released

I used to use it all the time windeployqt, Now this exe Still in Qt-5.15.0\bin in , Just use it in the same way as before .
