Breakpoint with hourglass

Giox79

Hello everybody,
I have an issue in the following configuration.

QTcreator 4.5.1, based on QT 5.10.1 (MSVC 2015, 32 bit)
Windows 7 PC
CDB installed from Windos SDK (versione 6.12.0002.633, ABI x86-windows-msvc2010-pe-32bit)
Compiler: MSVC 9.0 (both 64 and 32 bit)
QT 4.8.5 x86

I'm able to build the project, but I fail running the DEBUG. I built the code using the Debug configuration, and here is the generated CLI on te compile output panel:

	C:\Qt\qtcreator-4.5.1\bin\jom.exe -f Makefile.Debug
	cl -c -nologo -Zm200 -Zc:wchar_t- -Zi -MDd -GR -EHsc -W3 -w34100 -w34189 -DUNICODE -DWIN32 -I"..\test_2" -I"." -I"..\..\..\..\Qt\4.8.5_x86\mkspecs\win32-msvc2008" -Fodebug\ @C:\Users\parodig.EDG\AppData\Local\Temp\main.obj.6032.16.jom
main.cpp
	link /NOLOGO /DYNAMICBASE /NXCOMPAT /DEBUG /SUBSYSTEM:CONSOLE "/MANIFESTDEPENDENCY:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' publicKeyToken='6595b64144ccf1df' language='*' processorArchitecture='*'" /MANIFEST /MANIFESTFILE:"debug\test_2.intermediate.manifest" /OUT:debug\test_2.exe @C:\Users\parodig.EDG\AppData\Local\Temp\test_2.exe.6032.1623.jom
	mt.exe -nologo -manifest "debug\test_2.intermediate.manifest" -outputresource:debug\test_2.exe;1

Any breakpoint on the code appears as a red bullet with an hourglass on it and the code do not break at it.
The debug output panel is at the following link:

Link to debug output, pastebin

The source code is a simple hello world automatically generated by QtCreator

Any help will be appreciated.

Best regards
Giovanni

Hi,

Out of curiosity, are you locked to these old versions of Qt and compiler ?

Giox79

Hi @SGaist thank you for yoyr reply.
I have to use the MSVC 2008 because of a license company issue.

However, if needed, I can upgrade the QT library.
Do you think there is some issue related to my MSVC compiler?
Is there any bug already traced on the web? I was not able to find any document about this, but any help culd be useful.

Finally, I have a question, do you know why, on the kit panel, QtCreator suggests to use the CDB 64 bit, while I'm using a QT library version built for x86? I tried both CDB 64 and 32 bit, but I wasn't able to fix the issue.

SGaist

I'd go with at least Qt 4.8.7 since it's the latest and last of that series if you can't upgrade to Qt 5.

No I don't but I'd check the value of the compiler used within that kit.

hi @Giox79, from your debugger log I see that Creator wants to start a 64 bit CDB. so you should check your settings.

Regarding the old versions: I still use Qt 4.8.2 with MSVC 2010 and Creator 4.5, so your setup is not too exotic. I guess after correcting the settings it will work.

Giox79

Hi @aha_1980 thank you for your help.
I tried uninstalling the x86 Debugging tools for Windows and installing the 64 bit one but I'm not able to fix the issue.

I found, I think, an interesting news.
Looking at the "Debugger log" panel, as soon as I place a breakpoint on the source code, the text:

"ATTEMP SYNC"

appears, and nothing happens.
May be this can help to better understand the issue?

Tomorrow I will try updating the QT version as suggested by @SGaist

Hi @Giox79:

Hi @aha_1980 thank you for your help.

No, you misunderstood me :(

Look in your debugger log, line 7: dDebugger: C:\Program Files\Debugging Tools for Windows (x64)\cdb.exe: That clearly indicates a 64 bit debugger. As you said you are using a 32 bit compiler, I don't think that will work.

What do you have configured in QtCreator -> Tools -> Options -> Build & Run -> Debuggers? Which debugger is assigned to your Kit (same option page, Tab Kit)?

I don't think you need to reinstall Qt.

Giox79

Hi @aha_1980 thank you for your help.
I installed the 32 bit version of the debugger.
I think everything is fine, but nothing works fine...

Once again, I'm able to compile the source code, but in the debugger log I have the following output

Hi @Giox79

yes, now everything looks as expected.

Please create a report at bugreports.qt.io describing the problem and provide the debuggerlog there. Maybe the developer can say more to your problem ... my possibilities end here :(

aha_1980

The bugreport is here: https://bugreports.qt.io/browse/QTCREATORBUG-19989

@aha_1980 Thank you I forgot to link le bug that I submitted.
Thank you again
Have a nice day
