Problem with debbuging under windows 7

[ChrisW67]

The distributed Qt Creator binaries are created with 32-bit MSVC2010. I think OP's project is built with the 32-bit MingW compiler and matching Qt libraries.

I would start by doing a complete clean build of the project and making sure there are no zombie copies of your program running.

HEllo, i have installed VS version before, but i have "can not setup debugger"
so i have installed then MinGW version. Probably my aplication is compiled by
VS compiler, but Qt try debug it by debuger for MinGW.

I have clean my environment, reinstall Qt VS version and now try to install
win SDK and configure debugger. I hope it solfe the problem.

Thanks for responses!

Ech... I wasn't able to install MS SDK... FU**ING PC!!

Finally i have installed fresh MinGW version on virtual machine - windows XP.
At start it works great on some sample project.

When i import my projects, i have same problems during debugging: Huge lag,
can't see values of variables, gdborig.exe (debugging process?? ) take up to
1GB memory and 100% CPU time...

What i have to do to make single working program on that environment!!!???
I have lost many time, and have no effects...

Could be a reason using STL structures ? I use vector, stack, etc...

What do you mean "import my projects"?

You make a single working program in that environment by taking a set of source code, and compiling and linking it with a compatible toolchain and Qt libraries, and running it using a matching debugger. If you use the 32-bit MingW compiler and Qt library bundled in the official Qt Project then you use gdb to debug it. If you use Microsoft's compiler then you need a matching set of Qt libraries and Microsoft's debugger. In both cases the program must be compiled in debug mode so that meaningful single-step and source code debugging is possible.

Start with a simple "Hello World" program, set a breakpoint on the first line of main() and run it in the debugger.

What do you mean "import my projects"?

I mean i create new project in fresh installed environment from scratch,
then copy my cpp and h files, add to the project and build.

It was build successffuly, config is ok too - MinGW Compiler and proper
debuger ( there is no VS installed on machine ). Buy there are same
problems with debugging.

Like Chris said - i will start again from simple project. I it will
work i try to switch STL structures on my project with Qt, like
QList, QStack etc...

I have removed includes not connected with Qt (windows.h, map, vector ),
i use only includes started with Q. I use QFile instead of CreateFile etc...

When i enter the code below, and make breakpoint on some line, when it break,
then I hit F10 and program suspends... 100% CPU, +500MB memory used and
growing...

And don't know what is wrong.
Before mentioned function i open the file, allocate 8MB memory on heap for
file data, and close the file ...

any suggestions ?

Finally i removed F**ing windows and i have installed Ubuntu.
It's my first day on linux but I am quite pleased.

Program and debugger work well now.

Finally i have opportunity to work on linux, i hopy it will be great experience.

Problems in running Qt on my windows was probably becouse of damage
system and some exotic settings (ewf mngr etc... ).

Thanks for help, i think thread can be deleted.
