HelloWorld for Quick on MinGW32 freezes

MSarres

I have used QT with QuickControls 2 for a while.

I test my mobile app using MinGW32 in Windows. Recently, my app started to freeze at engine.load(...

I tried to install a new app and same thing happens.

I create a brand new app from QT Creator, using QT 5.9.2 and QuickControls 2.

This Hello World freezes the same way.

Does anyone know what this could be?

Thanks,

Marcos

Hi @MSarres, I don't know for sure, but perhaps it's related to your graphics/OpenGL drivers. What graphics card do you have? Did you update its drivers recently?

MSarres

@JKSH

Actually I have tested it in three different computers. All have the same problem.

Could it be that all computers are 64 bits?

Hi and welcome to devnet,

What version of Windows are they running ?
What graphic stack do they run ?

MSarres

@SGaist They are running Windows 10, all of them.

Sorry for my ignorance, but what do you mean by graphic stack?

The strangest thing is that everything worked fine a month ago. All of a sudeen all my installations stopped working.

That's what Windows Update does for you ;-) (Or, sometimes, installing a program.)

MSarres

@JNBarchan I regret I left Windows Update on :-(
But now I am a bit desperate. No QT installation builds correctly from now on.

@MSarres Try to update your graphics driver

Do they all have same graphics cards, or different?

MSarres

@JNBarchan Different graphic cards. Two Dell notebooks and one desktop.

@MSarres
Then, although I might still be worth trying, it doesn't seem so likely that a graphics driver update will solve your situation, which had seemed to be the suggested issue.

Are you able to test something earlier than Qt 5.9.2, that you know it used to work with? If I understand your posts correctly, that seems to have been the recent update which is common to all PCs?

MSarres

@JNBarchan My app used to work at 5.7.

But as no application works, I try to make a Hello World Quickcontrols 2.0 either on 5.9.2 also on 5.7 no success so far.

@MSarres
Well do also take the suggestion of the expert guys here, who said update gfx drivers, because they know a lot more than I do! They may know that engine.load() implicates the graphics specifically.

My best guess is that they all got the Creator update.
run
winver
and see if all have same windows version

I had some win 10 at work that needed driver updates after this BIG update.

JonB

@mrjj So that would be ... Windows Update, then ;-)

mrjj

@JNBarchan
Yeah, there is nothing like HUGE updates to whole OS to make
funky shit happen. So if he is seen seeing same on 3 different machines, I would assume he would recalling install some app on all of them so that leaves the normal suspect. Windows Update.

MSarres

@mrjj @JNBarchan tried everything now... Updated the graphical driver, and reinstalled all QT, versions 5.7 and 5.9.2, MinGW32

My Windows 10 version is 1709
.
Then create a brand new project at Projects>New Project>Application>Qt Quick Controls 2 Application

Same thing, the Hello World freezes at engine.load(

Could it have something to do with 32bits running at a 64 bit laptop?

This is so bad...

mrjj

@MSarres
Its not so likely its 32/64 bit issue as I assume it was same
bitness when it worked.

Did you update virus scanner recently ?

Btw 1709 is the Fall Creators Update. also huge.
Tons of people having issues.

MSarres

@mrjj What do you suggest? A Windows 7 Virtual Machine?

mrjj

@MSarres
Well if its due to a MS update. then we will hear soon here in forum.
So for now we must assume its something locally.
If you must work now, then yes a wm with windows would do it.

However, just check at worked and its 1709 too and tried a QML default project and no hanging.

There is nothing else that has issue on the pc ? I mean watching video ?

Since you have tried update gfx and reinstall Qt, it must be something external since its
all 3 pcs at same time.

I would find an openGL app and see if that runs.

You could also try the windows 10 refresh feature but it will kill some apps.
