Unexpected CDB Exit

dannox

Hi,
I have the same error. Did you get a solution for that?

I was getting this error yesterday. I found the the CDB version didn't match with the linked UCRT.

I'm using Qt 5.6 to develop my application I found that I need to manually link against ucrt like this

INCLUDEPATH += "C:/Program Files (x86)/Windows Kits/10/Include/10.0.10586.0/ucrt"
LIBS += -L"C:/Program Files (x86)/Windows Kits/10/Lib/10.0.10586.0/ucrt/x64"

And I found that the CDB version need to match the ucrt version. So I am using CDB 10.0.10586.0 now and it is working.

@dannox I did not find a fix for it yet, but I'm going to try @mcleary 's solution and reply if it worked.

I have the same problem. I tried @mcleary 's solution but unfortunately it didn't work for me.

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.

@mcleary
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.

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.

Destructor

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.

jsulm

@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.
