This text provides instructions on how to package and generate .exe files in Qt. The first step involves building the project in Release mode and recompiling it in QT Creator. The generated .exe file will be found in the release folder. However, additional Qt library files are required for the .exe file to run successfully on a computer without Qt installed. The second step explains how to run the generated .exe file on a computer without Qt by using the windeployqt command in the command prompt. The .exe file and its associated files can be copied to another computer for testing. The text also mentions that the same process can be followed using VS2010 and Qt5.0 plugins to generate .exe files that can run on computers without VS2010 installed.

Packaging Qt into an exe file#

Step 1#

How to generate an .exe file#

First, change the build mode of the QT Creator editing interface to Release mode and recompile!

Then click Run (ctrl+R)! In the project column, under the build directory, a folder named with "release" will be generated.

It contains the following files:

Open the release folder, which contains the corresponding .exe file!

At this point, clicking on the .exe file will not run successfully because we are still missing the necessary Qt library files.

Step 2#

How to run the generated .exe file on a computer without QT installed#

Specific steps: First, place the generated .exe file separately in an empty folder!

Search for QT in win10 and open the command prompt in the red box:

At this point, you can see that many files appear in the empty folder:

At this point, this .exe file can be run on a computer without QT installed!
You need to copy the folder where the .exe file is located to another computer in order to run it!
You can package this folder and send it to others for testing!

Note: The combination of VS2010 and Qt5.0 plugin can also generate .exe files and can be successfully run on a computer without VS2010 installed.

Step 1#

Change Debug to Release in VS2010, then start debugging (F5). After successful debugging, an XXX.exe file will be generated in the Release folder under the project folder.

Step 2#

Same as QtCreator software.

Step 3#

Same as QtCreator software.
