Run it with a debugger (F5) and it will show you exactly where the crash is happening.

A crash is usually caused by a dangling pointer.

Hi
Is it a clean default GUI project that crashes ?

You are using the mingw compiler that came with Qt ?
No custom install of compiler was used, correct ?

Also what platform ?

Sekhar

@mrjj
yes,it is completely clean default GUI project.
i am using mingw compiler that came with QT at the time of installing procedure.
i am using window 7.
i didn't use any custom install of compiler.

i was download QT-5.10.0 offline installer.

@Sekhar Please check your PATH that it not contains incompatible Qt or MinGW libraries.

Can you run a plain C++ console program? And a Qt console program?

Regards

Sekhar

@aha_1980
i tried console c++ program but doesn't work

jsulm

@Sekhar Do you have any anti-virus software running?

Sekhar

@jsulm
I doesn't have any anti-virus software's on my PC.
if i was tried to select new project--> non-QT project --> plain c++ application.
it will worked. but new project --> Application --> Qt widgets application (or) Qt Console and reaming application didn't work.

jsulm

@Sekhar Is E: a local drive or a network drive?

CroCo

I suspect the 64 bit issue. Please show us the .pro file and the whole project.

jsulm

@CroCo I doubt: he uses a 32bit Qt with 32bit compiler, works fine even on 64bit Windows.

CroCo

@jsulm he claims that but hard to tell if this is the case. We need to know when Qt installed which compiler being used. I recall long time ago similar problem occurred with me.

jsulm

@CroCo See the screenshots above and the build logs in QtCreator

Sekhar

@CroCo

this is my .pro file and doesn't use any cross compilers on it.

The following define makes your compiler emit warnings if you use

any feature of Qt which has been marked as deprecated (the exact warnings

depend on your compiler). Please consult the documentation of the

deprecated API in order to know how to port your code away from it.

DEFINES += QT_DEPRECATED_WARNINGS

You can also make your code fail to compile if you use deprecated APIs.

In order to do so, uncomment the following line.

You can also select to disable deprecated APIs only up to a certain version of Qt.

#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0

CroCo

@Sekhar do you have another version of mingw in your system? Also, when you installed Qt, which compiler did you use? Moreover, can you show the environment variables related to MinGW and Qt?

Sekhar

@jsulm
E: is my local drive not a network drive.

Sekhar

@CroCo
I think this is you want it.
