QtCreator crashed and now will not start due to segfault
-
Hello everyone, I'm having a bit of a struggle liking Qt-Creator ever since it crashed while I was working on it. I've re-installed Qt several times, but nothing is changing. Are there some hidden config files I should be removing? Does anyone else have this problem?
-
Hi and welcome to the forums
What version of Creator and what Os ?I have not have it crash for a long time (years)
so most likely something else wrong.What are you doing when it crashes ?
Also could you try upgrading your gfx driver ?
-
Qt-Creator 4.7.0 on Windows 10
I think I overloaded it clicking on settings(not exactly sure though)
I don't think the gfx driver's an issue because it was running fine yesterday, and I haven't had anything change on my machine. -
Ok, if it was working yesterday. then cant be the gfx is no windows update
or anything.Can you still reproduce it ?
-
Yes, Qt-Creator just won't open at all, even after I re-install the entire thing.
-
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.
-
I've deleted those already between installs

@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 -
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... -
I just debugged it and got this: Exception thrown at 0x670E5DA7 (Qt5Core.dll) in qtcreator.exe: 0xC0000005: Access violation reading location 0x7E5B8721.
-
Is it possible that the wrong Qt DLLs are loaded? Have you changed the PATH environment variable, for example?
-
Hmm I'll try adding it to the PATH xD
EDIT: that didn't work
-
No, that's not what I meant! I meant, have you done before? Or have you installed some program that did?
-
It's not corrupted because it's a clean install
-
already did that.
-
@TMcSquared
Best guess is that it gets wrong QtDLLs maybe via
path. -
My PATH variable has zero Qt paths in it. even after a clean install.
