Problem with Qt itself

Mohamed Fouzi

Hello everyone. I am encountering some serious problems in Qt. It started months ago, but wasn't that bad, but now, it makes the usage of Qt impossible.

I am using Qt 5.8 with Qt Creator 4.2

Problem:
When i open Qt Creator , it froze, and still like that till i kill the process from "task manager". It started months ago, but, after 2 or 3 restart, it worked. Even if, sometimes, when i wrote code, it froze.
Now, it freeze systematically at start.

Also, i'm trying to install the new Qt 5.9.. but i can't help it, the installation also freeze after some time.
if anyone can help, i'm listening. Thank you

Just out of curiosity: what's your operating system?

Mohamed Fouzi

I'm using windows 10, and installing Qt MSVC.

Hi, just guessing, but have you tried disabling your anti-virus?

Mohamed Fouzi

@hskoglund : I don't see really why or where it can be an issue, even though i will try and see.

Might also be a problem with the GPU driver. My general advice for Windows platforms (although it hurts unless you're in a virtual machine) is to reinstall everything, including Windows.

Mohamed Fouzi

Re-installing windows ?! I want to know if anyone encountered this kind of problem before making this step.

Isolate your problem. Is this only a problem with Creator when running your application? Does Creator suffer the same symptoms when you use the example applications ?

You could upgrade Qt + Creator and see if the issue was just that version. I never had 5.8 problems that I recall, I'm on Qt pre-compiled for win10 using mingw5.3.0 && MSVC15 compilers. But I do keep Qt at the current stable using the online installer.

It can: anti virus software can have false positives and block some executables or DLLs from Qt because it thinks it is malware. It can even happen with your own application - anti virus software can block it from executing.

Mohamed Fouzi

@jsulm Of that, i know. My antivirus used to block the Dlls, but i marked them all as safe. But, i will give it a shot today, who knows.

@6thC I've upgraded, but nothing changes.

The thing is, anything related to Qt freezes. I tried to launch Designer, it gave me the same results. When i put the cursor over an option, it becomes highlightened, but when i move the cursor away, it stays like that..

@Mohamed-Fouzi As @Wieland said it could be your GPU driver

Did you start by completely uninstalling whatever Qt you have and then install the latest?

Mohamed Fouzi

I reinstalled Windows 10 and everything needed, (net.Framework, msvc, new Qt..) but nothing changed. Although it opens and let me click on the toolbar, but then freezes.

Hi
As a fast test , could try start Creator from cmd prompt with
C:\Qt\Tools\QtCreator\bin\qtcreator.exe -noload Welcome -noload QmlDesigner -noload QmlProfiler

and say if it still freezes.

Mohamed Fouzi

@mrjj Thank you very much for your answer. However, even if i'm able now to open the file directory to choose the project, it freezes immediatly after that.. It's confusing me.

@Mohamed-Fouzi
Unless its a virus scanner blocking make.exe or Creators file access I have no idea what else it could be.
I assumed you have tested the VS compiler works correctly from its own IDE ?

Mohamed Fouzi

@mrjj Yeah, it does. I will try for the last time to stop the antivirus and see what will happen then.
Anyway, thank you for your help.
