I develop using Mac then recompile for Linux and Windows using Qt 5.6
I recently completed a first run of a project under Mac, it compiles and runs w/o problems under Linux, but when I move my source to a Windows machine it compiles fine, but crashes with an error 255. when run. I'm at a total loss as to how to start debugging this problem. I've never had to use debugging for Qt, other than qDebug(), and have no idea where to start.
You should create a debug build and provide forum with a stack trace.
That might give a hint on what is crashing.
Thank you. I'll do that and post back.
