Please help: Can't debug 32-bit apps on Windows 7 x64 w/ Qt Creator

Hi guys,

I'm new to this forum and fairly new to Qt.

I'm running Windows 7 x64. I have Visual Studio 2010 installed and also Windows SDK v7.1. I've installed Debugging Tools for x86 and x64.

To install Qt, I downloaded the source for 4.7.1 and compiled for x86 and x64. I am using Qt Creator 2.1 RC.

I can switch between compiling 32-bit and 64-bit by switching between my Qt 4.7.1 folders. This works great.

I'm not expecting to be able to debug 64-bit apps with the 32-bit Qt Creator, but I think I should be able to debug 32-bit apps.

When I try to debug, everything looks right, but my breakpoints don't get hit. I can put my breakpoint at the first line of code in my main function and nothing -- it flies right by.

I tried setting the option to automatically break on exceptions and then put a throw in my code. This breaks, however, it doesn't break in my code; it breaks in the thread window.

Any help is greatly appreciated.

Thanks very much.

Wow, nothing? Am I SOL?

I think the issue might be missing debug information. Does anyone know how I can resolve that? Thanks.

my scenario is quite similar, but simpler, just qt-creator 2.01 and qt4.7.1 with vs2008 under win7/64-bit. Only downloaded the 2 qt windows binaries, and installed the x86 Debugging Tools besides the official 64 bit version of it, took me a bit to figure out that one ;) Qt-creator found and recognized the appropriate 32-bit cdb, and building the debugger helper also worked. And also no problem in debugging the compiled qt apps, with breakpoints, of course only 32-bit. Maybe at least worth giving it a try.. :D

Hi all...

For those interested. I finally got debugging working. I installed Qt Creator 2.2 Beta (released today) and viola, debugging works! Wonderful. Thanks to all those that made it possible. :)

I have the same problem, can you tell me what viola is?


did you mean "et voilà !" ?
:p

Hi,

Yes, I meant "et voilà !"... sorry for the confusion. Try installing the latest build of Qt Creator 2.2 Beta: http://developer.qt.nokia.com/prereleases

After installing, VS 2010 wouldn't compile C++/CLI projects correctly -- errors about trying to compile x86 using x64 platform.

A simple reboot fixed that.

my problem is that: I can compile on debug and x86 the program but I can't run it

in release it works correctly.

this is the error i get:

this application has failed to start because the application configuration is incorrect. Review the manifest file for possible errors

I'll try to reboot

Sounds like a dependency issue. Have you used Dependency Walker?

thanks, but I don't know what to do. what I'm supposed to see?

from the linker I can see that there is a .lib shared by release and debug.

Depedency walker says that there are missing dlls, but when i add them it find other missing dlls WTF:confused:
