dll missing
-
Hi. I am a beginner in this.
I am developing a program, etc.
When I open my program from the qtcreator it opens normal. but when I go to release/(name) .exe it tells me that qt5gui.dll, qt5core.dll, qt5network.dll and qt5widgets.dll are missing.
I tried putting the files in windows/sysWOW64 and it works fine, but as I do so that someone else can open it on their desktop without putting those dll.Thank you so much, I waiting for your answers

Hi and welcome to the forums
What you need is a so called deployment folder.
It just means , you need to place the DLLS next to the exe to have it run on other systems.
There is a tool to help get the needed DLLS.
https://doc.qt.io/Qt-5/windows-deployment.html
( how many dlls it needs, depends on what features you used in your program)Also skim over this. it explains what the folder is and structure:
http://www.tripleboot.org/?p=138and DO NOT put any of the DLLS in windows/sysWOW64. its not a good idea. :)
When you have a deployment folder. you then use an install maker to make a setup.exe other people
can just run and it copies the dlls to the program folder for your program to use.
That is the normal way. -

@Zetta
Just a few hints.
Make exe in release mode
never mix Qt DLLs with D in name and no D.
(debug Qt dlls have D last in name )
Sometimes on some system, like win 7, the compilers runtimes dlls are also needed.
Like for visual studio or mingw. -
