I created a new Qt-Widget project, built it, put the windows.dll where it belonged, and tried to run it. I got the error:
Cannot mix incompatible Qt library (version 0x50402) with this library (version 0x50401)
I have only Qt 5.4.2 installed. I did not make any change to the project in the very simple form in which QtCreator created it.
My Qt Creator is:
Qt Creator 3.4.1 (opensource)
Based on Qt 5.4.2 (MSVC 2013, 32 bit)
Built on May 28 2015 19:07:19
From revision 29d81424a2
In the same directory as this project, I have another project created and built with the same Creator, and it works fine.
What could be the difference?
