Debugger helper

[ktk]

How nice, I made the debugger helper working under windows (latest QT release 4.5.2, QTCreator 1.2.0).

- Tools->Options->Debugger->Cdb (click under the link "Debugging Tools for Windows") and Install the debugger tools

- Tools->Options->Debugger->Cdb->autodetect
- Tools->Options->Debugger->Debugger helper-> Debug Debugger helper

and now it works!

That's probably pure accident. The comments in the code regarding "Debug Debugging helpers" suggest that this was intended for internal use only and
not meant to be present in a "release" build.

Try to use version 1.2.1. That has several critical fixes in that area.

Oooops, I failed to notice Creator 1.2.1! Installed and things are much better.

Thanks,

I also have this problem on openSUSE 11.1, KDE 4.2.2 (110), Qt 4.1.1, QtCreator 1.2.1 - i.e. I can't see contents of QStrings, etc. (forced to use qDebug() << ....).

Does anyone have the magic bullet for linux/openSUSE/KDE?

The message "Debugging helpers not found" (along with the inability to use helpers) persists even though "Rebuild" seems to be a success and the libraries (and links) seem to be in the right place; log output is :

I think this was have something to do with administrator privilages on the computer.
I am having the same problem (debugger helper does not work despite green checkmark).
I tried rebuilding it as well, and my log file shows the same thing

This exact problem from the original post seems to still exist in latest version of QT Creator (1.3.1). Unable to rebuild the debugging helper, and get what look to be the same errors.

Followed these steps up until the last one, which no longer seems to be present in QTCreator, and it still complains about no debugger helper being present and will not show me the values of variables. Really terribly frustrating that it isn't even straight forward to do basic things like debug a QT application...

Thinking that something can't be done because I'm unable to do it is a very egocentric approach. Please don't do that.

You are using MSVC as your compiler, right?

First of all, debugging works independently of the existence of the Debugging Helpers. They "only" provide a means to get a more direct display of types like QString, QHash, std::map etc. Without them you still have access to all your data.

Second, http://qt.gitorious.org/qt-creator/p...AskedQuestions does contain an answer to the question "The debugger does not work. What kind of information is helpful? "

Hi everyone!

I read this topic and many other, but still can't understand how fix this trouble "debugging helpers not found".
I have latest version of SDK Qt(4.6.2) and Qt Creator(2.0 beta -newer than SDK) to date:

Firstly I see to this, seems that's all right:

Elseone rebuilt qtc-debugger-helper:
