Qt desktop app crashing at startup

Jennise Hall

Darn it. It is a typo. Now it's working. I apologize for wasting your time. I'm not sure when the typo creeped in. I'm going to strip down my application in to the simplest repeatable case.

Qt 6.8.1

Pardon?

You pasted maireturn a.exec(); which obviously means your code could not compile. So how come there is a stack trace showing showing it running and inside the exec() and you say it crashed?

Jennise Hall

Yes, That has me stumped. You're right it wouldn't have compiled with the typo. So, the typo must have happened when I pasted the code but, I'm no longer sure because once I fixed that line of code the program started running consistently. Nothing about this crash makes any sense to me. I am going to strip the actual application down to the simplest point that generated a crash. I'm also thinking I should update to Qt 6.11.

I would also check whether you have somewhere a macro that has that name or maybe a define.

The word "maireturn" is a Tagalog (Filipino) verb that translates to "to be able to return" or "can be returned" in English

"Mai" is month May in German.
So maireturn a.exec() should return an int 10 :))
(months to May)

:P

I wasn't expecting a linguistic analysis for a typo :-D

LOL

useful information though.

Jennise Hall

Well, my application is back to running. I got frustrated trying to strip down my application and decided to throw a couple of spitballs at the wall. Not for the first time, I deleted the pro.user file making sure some of the settings that were not included in the DummyMainWindow project. Re-opening the project after that and the project was once again running. I am not really sure what happened but I'm working again. So I am going to close this topic.

Thanks for catching the typo...and for the "linguistic analysis" of the typo. LOL
