We all know Qt Cross platform features , So in addition to enjoying The signal - Slot Besides the development convenience brought by the mechanism ,Qt There are also simple ways to publish .

1. Qt Creator kit 

In the installation  Qt Creator when , Will let you choose to install Kit, There are about four kinds of , As shown in the figure below ：

MinGW 32-bit

MinGW 64-bit

MSVC 20XX 32bit

MSVC 20XX 64bit

Say... Loosely ,

MSVC 2017 64 position , Is used for Microsoft 64 position C++ compiler ,MinGW 64 position , Is the use GNU Of 64 Bit C/C++ compiler .

The result is what the software they build and compile depends on dll Each are not identical .

2. MSVC disadvantages

Use MSVC The disadvantages of building and compiling are very serious .

1. It must be carried in the release package vc_redist.x64.exe

2. The user must install vc_redist.x64.exe, Double click to open our exe

How ugly and disgusting . and MinGW There is no such trouble .

3. A simple way to publish

stay D disc Create a new folder , Name it myapp, That is to say D:\myapp Folder .

3.1 Generate exe

1. stay Qt Creator Select from the operation configuration interface in the lower left corner ：

take myapp.exe Copied to the D:\myapp In the folder .

3.2 Use windeployqt.exe Release

Use Qt It's official windeployqt.exe Tools release our software .

Be careful ： The four above kit All have their own windeployqt.exe Tools , So choose Release Used when kit Corresponding  windeployqt.exe Tools .

What we use above MinGW 32bit, So we ：

1. The start menu ->Qt5.12.9 -> Qt 5.12.9(MinGW 7.3.0 32-bit), Input

windeployqt D:\myapp\myapp.exe 

there myapp.exe To replace with your exe name .

2. take D:\myapp The folder is compressed to zip It can be sent to users . After the user unzips, double-click exe You can run .

Tips ：

If you can't find it in the start menu minGW, You can go straight to Qt Installation directory lookup , Similar to the following directory ：

C:\Qt\Qt5.12.9\5.12.9\mingw73_32\bin

3.3 （ It's not necessary ） Copy depends on dll

If you find double clicking exe Run time error , Tip the lack of xxx.dll file , You can enter your MinGW 32bit Where bin Folder , as follows ：

C:\Qt\Qt5.12.9\5.12.9\mingw73_32\bin

If you use it MinGW 64bit , The corresponding is mingw74_64\bin.

The inside No use Qt5 At the beginning dll That's what we're looking for dll file , Copied to the D:\myapp In the folder .

As for others dll, Look at you Qt Copy whichever is used in the project .

I don't know , All in this document dll  Copy to desktop myapp Folders are also OK , The result is a large volume of compressed packets for users .
