Compile the Release version and copy the dependent library files

Select Release mode

Use the windeployqt.exe command to extract the used DLL library

Open Qt’s Mingw command-line interface:



On the command line, switch to the folder where the EXE file is located and run the following command:

windeployqt lock.exe
Copy the code

This command will copy all library files used by the exe:

E:\qtwork\lock-Release\release>windeployqt lock.exe
E: \qtwork\lock-Release\release\lock.exe 32 bit.release executable

As shown below, the copied file:



Test if it can be run directly, sometimes it may still be incomplete, then follow the prompt which is missing, find which one, fortunately, this can run:



Now you can package the folder.

Package using Inno Setup

Download and install

Download and install will not be introduced in detail here, Windows application installation is basically the same, all the way “next”.

After the installation is complete, start packing

Start compiling and packaging

Follow the steps above:



You will be prompted to save the script:



Compile package:

Packaging complete

Install the test

As with installing Windows, the “next step” along the way:





This icon is missing because this program was compiled without setting the icon. Double-click this icon to run:



It works fine, and now you can release the package and install it on another computer.

Note: versions after Qt5.7 no longer support XP.
