[SOLVED] QtCreator 4.8.1 - Qt libraries 4.8.5 for Windows (minGW 4.4) and Mingw 4.4 GDB Debugging HELL

RavensAngel

All,

can you please help me to find what is going on.

First i want to let you know that :

I'm working on Windows7 64bit
I uninstalled all previous version of any qt related component (QtSDK, QtCreators, Qt Libs, Own build qt versions, etc)
I also deleted all data within my appdata folder related to any qtcreator/qt version ever.

So,

I downloaded:

"Mingw 4.4" using forum thread (http://qt-project.org/forums/viewthread/21079), see last comment!

"Qt libraries 4.8.5 for Windows (minGW 4.4, 317 MB) (Info) (http://qt-project.org/downloads)

"Qt Creator 2.8.1 for Windows" (53 MB) (Info) (http://qt-project.org/downloads)

I installed:

mingw4.4 (simple copy to c:\qt\mingw) and added the location to system PATH

Qt libs 4.8.5. Refering to the mingw i downloaded

QtCreator 4.8.1

I configured:

Manually added Qt version 4.8.5 within the Tools >> Options >> Build & Run >> Qt Version tab. (in my case: c:\qt\4.8.5\win32\mingw\shared\bin\qmake.exe)

I adapted the Desktop (default) Kit, which was under the manual field, and set the following settings

Name: Desktop
Device Type: Desktop
Device: Local PC ( default for Desktop)
Sysroot: <empty>
Compiler: MinGW (x86 32bit in c:\qt\mingw\bin)
Debugger: GDN Enging Using: "C:\qt\mingw\bin\gdb.exe"
Qt version: Qt 4.8.5 (shared)
Qt mkspec: <empty>
--> <empty> = empty string

I created a new Simple Helloworld Qt Gui Application (not qml).
Which builds perfectly on both debug as release.
But, when trying to start it in debug, i get the message="The gdb process terminated", title="Unexpected GDB Exit"

The release works perfect,I tried to run my app from console using gdb which seems to be working perfect as well...

So the question: WHY HO WHY, is QtCreator NOT working at all!

Can someone please help me, as I spent a whole day trying to install, uninstall, clean install and nothing seems to be working: indicating I 'm still doing something wrong. The information coming from QtCreator\GDB is not very helpfull at all, leaving me in the dark...

Hoping for the best, I thank you for any feedback or comment!

PS: still trying to fix it myself :)

Hi,

... added the location to system PATH

[/quote]Don't do that, because it increases the risk of wrongly-linked DLLs. Remove all references to MinGW, GDB, and Qt from your PATH.

Although not the solution, I thank you for the info.

On the other hand, I found a solution for my problem.

I was smart enough to copy the mingw and pythongdb directories from the QtSDK i had previously installed. I started using those 2 components, and all seems to be working after a small configuration change.

It's a pitty that nowhere i could find any information towards this (or I didn't find it) in the QT project docs.

I had to change the debugger in the Desktop kit (see above):
Debugger: GDN Enging Using: C:\qt\pythongdb\python_2.7based\gdb-i686-pc-mingw32.exe

That seems to do the trick.

I hope this is helpful for others having troubles setting this environment up.

Thank you for sharing your solution. Happy coding!
