GUI Application crashes before launch

[SGaist]

Do you have any external dependencies for your application ?

Hi @SGaist,

What do you mean by external dependencies?

At the beginning I've tried to run the project that I've worked long time ago, but after I haven't be able to do it I try to run a bare new one.

Right now I'm trying to run a default project, the one that is created by default when we create a new project:
New->Project->GUI application...

Thanks again

By external dependencies I mean any library that you are using in your application.

Do you mean that even a default project doesn't start ?

[luisrcastan]

@SGaist ,

That's correct, a default project does not start...

@luisrcastan Create a console application and check whether this one starts. If it does then most probably it is an issue with your graphics driver.

Hello @jsulm

I've created a new project and it seems to work properly...
But when I added a simple code like
unsigned int x;
x=1;

and I set a breakpoint in x=1;

The next messages pop out:

If I have to guess.... i think I'm not using the right compiler, because the compilation does not set any kind of error, but the exe file does not run properly.

How can I know that I'm using the right compiler?

Thanks for your support

@luisrcastan What happens if you start this app without debugger (Strg-R)?

[luisrcastan]

Hi @jsulm ,

At first look seems like it is working correctly, but as I see, the instructions do not execute.
With a new project I added a simple printf("Hello word"); then the system("PAUSE"); instruction.
The application output shows:

The console application window does not print anything:

Thanks

@luisrcastan
This is guesswork, but if it were me because of where it falls over and the random exit code I would be checking:

1. Are you sure the program is finding the correct versions of MinGW C runtime startup library (and standard libraries), and that those are the versions matching what is expected at compilation time?

2. Does it make any difference if you compile not-for-debug?

3. Have you tried running your program not from inside Qt Creator?

4. Take your "Hello world" program and compile it as a standalone C/C++ program quite outside of anything Qt, using the same MinGW compiler. How does that behave?

Hello guys,

Since I thought this was related to some internal configurations, what I did is to clean my PC, I uninstalled all the application that I'm not using currently, cleaned all the frameworks and all visual studio versions.
After this clean up, I install QT and the application is running without any problem.

Thank you all for your support.

Best regards
