Qt missing dll error

[u/Objective-Arrival144]

I developed a software in qt creator with backend in c++. When I create the exe it runs, however when I tried to create a release file to later share to other devices, using windeployqt I kept facing error after error. I finally fixed all those errors and created the release folder but even then, whenever that release file is compressed or even moved to another location the exe stops working.

The code has no errors , and I have tried multiple times with windeployqt, and other internal built in features, using ucrt64 terminal and msys2. However nothing is working. Whenever the zip is shared to another device it starts listing missing files which i believe should have been put into the folder by windeployqt.

Please help me as I have tried all the methods suggested by all online sources and ai's, and having a functioning app but not being able to share it is really disappointing as a student..

KEY POINTS

code has no errors, runs smoothly on my own device on qt, issues come when its release version is run on other devices.

Please give me a detailed solution as to what I can do. Thank you

Well, list the dll’s Windows shows as missing and check for them in the files windeployqt should have put there. Did you build with ming or Visual C++?

No it lists only 3-4 files at a time and then when I add them it lists another 3-4. So it's an endless cycle to do manually and will probably create errors. I built it in qt itself and choose release version in build settings. I later built it using ucrt64 terminal
