Unexpected CDB Exit

[bitlixi]

I got the same error form. Finally found that some DLL needed is missing. You could click the exe file in DEBUG to find which DLL is missing.

@bitlixi thanks for the hint, I indeed checked the .exe in debug folder. Turned out my Qt/bin folder had magically forgot Qt5OpenGLd.dll

I had the same problem. I had incorrectly picked the x86 cdb version instead of the x64 version in configuring the kit.

Just for info: using -L before the library path string is wrong on my Windows 7 system with Qt 5.9.1.

I had the same unexpected CDB Exit since Qt Creator version 4.3. In Qt Creator 4.2.2 CDB works just fine.
The solution for me was uninstalling Python 2.7. It is still a work around for me, because I need Python 2.7 for compiling Qt WebEngine from source. Does somebody have a working solution for having Python 2.7 and Qt Creator 4.5 and CDB installed in parallel?

I have the same problem since the big windows 10 update this week.
I have not find a solution yet.
If someone have, it would be great to share. Thanks.

Hi
Just noticed i have same issue

Thank you windows update \o/

[Sriep]

Yes me too.

I switched from 4.5.0-rc1 to 4.5.0 and it went away. Not sure if that was a coincidence.

@Sriep
I reinstalled Qt and it also worked again.

@mrjj
i just ran the " repare " function of Visual studio 2017 installer and it worked again too.

My solution of this issue:
I've check my exe by Depends, and... I miss some dll, linked by .lib!
Then I put this DLL into System32 - et voila! CDB work now.

@Destructor You should not put them into system32 directory - put them in the same directory where you exe is.

@bitlixi's advice worked for me

[xenovas]

same problem.. could someone provide the steps in order to overcome this issue ?

[mrjj]

@xenovas
Hi
If you are using the visual studio compiler. First step could be to find the entry in
Add Remove Programs and ask it to repair and see if that fixes anything.

[xenovas]

@mrjj thank you for your response.. unfortunately didn't work for me..

[mrjj]

@xenovas
Ok, then you can try start the Qt maintenance tool and use it to reinstall Qt.
Did this happen after you installed visual studio update or similar ?

[xenovas]

@mrjj hello again, problem fixed for me.. i was using the wrong pythonpath..to fix it i have deleted the pythonpath pointed to python 2.7 Lib from my env variables and i have only kept the pythonhome variable pointing to python 3.7.2.. Thanks

For me this pops up when the application executable cannot find the required dlls for the application to run.
First click on the executable/build application in your respective debug/release folder and check what dlls it is asking for.
Find the respective dlls in your external framework files (usually in the bin/relevant architecture) and copy them in the qt application/builds local directory.
