Debugger goes to dump in Qt Creator 5.2.0



  • Hi,

    I have Qt Creator 5.2.0 installed. I set debug configuration, set breakpoint and launch my project in debug mode. When cursor is set on breakpoint I press F10 (Step over) but cursor does not change its position. When I press F10 (Step over) second time I get the following Execution error: "Cannot continue debug process. Warning: Cannot insert breakpoint -439. Error accessing memory address 0x78ab0050. Input/output error and Debug is stopped. Could anybody help in solving this problem,

    Thank you in advance.

    welcome to devnet

    You probably have installed one of the first entries from the download page. However, it states there:
    [quote]
    The binary packages include Qt 5.2.0 libraries and Qt Creator 3.0.0.
    [/quote]
    There is no Qt creator 5.2.0 available yet.

    In order to give others a chance to help you, you need to give details on OS, compiler and stuff.

    Qt creator is just an IDE, but you need to have a compiler and debugger installed. You can check already the settings under Tools-->Options-->BUild&Run
    The entries under tabs "Kits", "Qt versions" and "Compiler" should give no warnings or other special signs.



  • Hi koahnig,

    You are right. I use Qt 5.2.0 with Qt Creator 3.0.0.
    Details on OS: Microsoft Windows XP Professional Service Pack 3 Version 2002.
    Details on compiler and stuff:
    Qt from this site: qt-windows-opensource-5.2.0-mingw48_opengl-x86-offline.exe
    Build configuration; Debug
    Build steps:

    1. qmake: qmake.exe Connect_Q.pro -r -spec win32-g++ "CONFIG+=debug" "CONFIG+=declarative_debug" "CONFIG+=qml_debug"
    2. Make: mingw32-make.exe in C:\DevTools\Qt\Qt5.2.0\Tools\QtCreator\bin\build-Connect_Q-Desktop_Qt_5_2_0_MinGW_32bit-Debug
      Clean steps:
    3. Make: mingw32-make.exe clean in C:\DevTools\Qt\Qt5.2.0\Tools\QtCreator\bin\build-Connect_Q-Desktop_Qt_5_2_0_MinGW_32bit-Debug

    Under kits should be a debugger set. You typically have to click on to the actual kit you are using.



  • Yes, I checked all these settings:
    Kits: Auto-detected: Desktop Qt 5.2.0 MinGW 32bit (Extracted from Kit Qt 5.2.0)
    Manual: No
    Qt versions: Auto-detected: Qt 5.2.0 MinGW 32bit (location qmake: C:\DevTools\Qt\Qt5.2.0\5.2.0\mingw48_32\bin\qmake.exe)
    Manual: No
    Compilers: Auto-detected: MinGW 4.8 32bit (compiler path: C:\DevTools\Qt\Qt5.2.0\5.2.0\mingw48_32\bin\g++.exe)
