QtCreator crashed and now will not start due to segfault

mrjj

Ok, that is odd.

there is
C:\Users\username\AppData\Local\QtProject
C:\Users\username\AppData\Roaming\QtProject
which can be left over even if reinstall.

It should be pretty safe to delete, but Creator will forget anything then.

TMcSquared

I've deleted those already between installs

mrjj

@TMcSquared
and it still crashes ? wow. thats new.
Do you have sessions enabled ?
also , have you tried starting it from a shell (cmd)
to see if anything is written ?

also when starting in cmd.
try adding
-noload Welcome

TMcSquared

I get a segmentation fault when I run it from the cmdline both without and with arguments.

There's, oohh, a 1% chance that if you try running Qt Creator from within a debugger like Visual Studio (if you have that...), when it faults you'll get enough information from the stack trace to hazard a guess as to where it's going wrong...

TMcSquared

I just debugged it and got this: Exception thrown at 0x670E5DA7 (Qt5Core.dll) in qtcreator.exe: 0xC0000005: Access violation reading location 0x7E5B8721.

@TMcSquared

Is it possible that the wrong Qt DLLs are loaded? Have you changed the PATH environment variable, for example?

TMcSquared

Hmm I'll try adding it to the PATH xD

EDIT: that didn't work

aha_1980

@TMcSquared

No, that's not what I meant! I meant, have you done before? Or have you installed some program that did?

Take a look at qt.conf in the creator/bin directory. If it's corrupted then plugins wont load.

TMcSquared

It's not corrupted because it's a clean install

mranger90

The try wiping out the creator files under AppData\Roaming\Qtproject

TMcSquared

already did that.

mrjj

@TMcSquared
Best guess is that it gets wrong QtDLLs maybe via
path.

TMcSquared

My PATH variable has zero Qt paths in it. even after a clean install.

mrjj

@TMcSquared
I have no idea then.
last test
can you start with
qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
from shell and see if still crash ?

TMcSquared

:O It opened with qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler

Hi,

Then it sounds like a graphic driver issue then. Are you sure there wasn't any modification in that regard on your machine ?

JonB

@TMcSquared
You could check whether Windows Update snuck in and did anything since it last worked... :)

TMcSquared

That's completely possible, thanks for your guy's help!
@SGaist I have no idea, it quit working while I was logged in.
