QT creator 7.2 gdb not recognized

dahu74fr

Hello
i tried to install QT creator 7.2 on my computer running windows 10.
Everything is ok except for the debugger gdb. it is not recognized.
i install the same package on the computer of a friend that i was preparing and all is ok.
debugging works fine. i tried to copy all the installation from the friend computer and paste on my computer and have the same issue, gdb not recognized.
some one has an explanation ?
thanks in advance.

@dahu74fr Did you also install MinGW using Qt Online/Offline Installer?

dahu74fr

@jsulm yes mingw was installed with the online installer

@dahu74fr Do you see any warnings/errors in "Debuggers" tab?

@jsulm What i see is that :

jsulm

@dahu74fr Put mouse cursor over the red icon with exclamation mark: what does the pop-up show?

@jsulm could not determine debugger type

The data that you are seeing in the dialog is saved under %appdata%\QtProject\qtcreator\debuggers.xml

I have for example a MinGW GDB 11.2.0 like this:

 <data>
  <variable>DebuggerItem.2</variable>
  <valuemap type="QVariantMap">
   <valuelist type="QVariantList" key="Abis">
    <value type="QString">x86-windows-msys-pe-64bit</value>
   </valuelist>
   <value type="bool" key="AutoDetected">true</value>
   <value type="QString" key="Binary">C:/Qt/Tools/mingw1120_64/bin/gdb.exe</value>
   <value type="QString" key="DetectionSource"></value>
   <value type="QString" key="DisplayName">GNU gdb 11.2.0 for MinGW 11.2.0 64-bit</value>
   <value type="int" key="EngineType">1</value>
   <value type="QString" key="Id">Debugger.qt.tools.win64_mingw900</value>
   <value type="QDateTime" key="LastModified">2022-03-21T04:50:11.000</value>
   <value type="QString" key="Version">11.2.0</value>
   <value type="QString" key="WorkingDirectory"></value>
  </valuemap>
 </data>

You could close Qt Creator. Open the debuggers.xml file and change the EngineType to 1 and see what Qt Creator is doing afterwards.

The other location where the debugger can reside is c:\Qt\Tools\QtCreator\share\qtcreator\QtProject\qtcreator\debuggers.xml.

But if gdb --version doesn't start from command line, then it doesn't matter what the debuggers.xml file contains since you won't be able to do any debugging.
