Don't do this. Adjust your PATH env var accordingly and use windeployqt when you want to deploy your app. Your are missing dll and plugins

@HQ2000
So purely OOI could you comment on why thatforeachhas not copiedQt6Gui.dllas I asked earlier? However you say you know it works without that, somehow.Confirm you are not building your project for debug?
Remove everything on your
PATHenvironment variable so we know it is not picking something up somewhere?Lifetime Qt Championwrote on 2 May 2025, 14:13 last edited by Christian Ehrlicher 5 Feb 2025, 14:14@JonB copying dlls around manually is wrong. The PATH env var has to be adjusted.

? Of course, I know! I was just trying to diagnose where the OP's problem might lie, given what is in the makefile. I posted before your post. -

where the OP's problem might lie,
The problem is, that he is copying only half of the required stuff because he is doing some strang stuff manually for no reason.

Yes, I did some things manually on purpose. Private data.. -
As I already wrote - don't copy stuff around as it's wrong as it's missing things. Adjust your PATH var accordingly so that the Qt libs are properly found.

You mean I should just add their absolute paths to the PATH var? -

Again: add the path to the Qt dlls to the PATH env var.

Did it, nothing changed. (I restarted the project, of course)
Same with deleting the associated environment vars@JonB
It did. But it is not needed, I viewed it in the Dependency Walker -

Then you would get an error about missing dlls. You have some wrong dlls around somewhere.
Delete all dlls you copied around, don't copy dlls around in your CMakeLists.txt or anywhere else during your build, use a clean build dir, set the env var accordingly and start it from the command line where you also started the dependency tools from... -

I did not copy around any DLLs, this is a clean build dir (CLion pre-config)
I will try it.Added the env vars:
Still get the Error messages that exactly these ones are missing...

Added the env vars:
You write that followed by a list of DLLs. What do you mean you did to what environment variable? Also you no longer list the Qt DLLs?
Still get the Error messages that exactly these ones are missing...
If you mean the 4 in that list are reported missing then you have not set your
PATHcorrectly.I am lost.

@JonB path var sorry, I don't list them because it does not show the error "xy.dll not found", I DID set them correctly, I copied their paths through the explorer -

Sorry for all the inconvinience, I will try to express more exactly to avoid this kind of misunderstanding
