Qt Creator Crash

cmessineo

Hello, are there any log files to figure out why Qt Creator is crashing?

I'm using Qt Creator 2.5 and 2.41 and they both bail out with a segmentation fault.

Using Ubuntu 10.04

I am having the same error as this bug report: https://bugreports.qt-project.org/browse/QTCREATORBUG-7289

Thanks

Hi, ~cmessineo!

Try to execute qtcreator from Terminal.
@
qtcreator > qtcreator.log
@

It must write qtcreator debug output to qtcreator.log

We try to not spam the console with debug output, so as long as you don't add some yourself the log will not be very helpful.

Try getting the core file for your crash (that is basically a memory dump done by the OS whenever a segfault happens). You can extract a lot of useful information from that via the debugger. I am not sure how to turn those on in ubuntu though.

AFAIK, Ubuntu doesn't create core-files by default.

All I see is this in the log file:

call callback
Segmentation fault

Thanks
I'll see if I can get a memory dump

tucnak: Yeap, that is why I wrote "not sure how to turn those on in ubuntu". You can turn core files on, I've seen people use them on ubuntu. I am sure there is some documentation on how to do it available somewhere.

Try using
@
ulimit -c unlimited
@
at your prompt before running creator to enable core dumps.
