You would have to change the qmake.conf in the makespecs. It’s a nasty trick and will probably cause conflicts.

However, you should always be able to specify whether you want to use the wchar_t or char version, regardless of the UNICODE macro.

Thanks!
That helped alot! Exactley what I was looking for.

unfortunatley I can’t specify the string type because it’s output from one 3rd party function whose type is specified by the compiler to a second 3rd party function that only accepts a particular type. I guess I could write a conversion script buy that’s not what I’m looking for…

I had the same problem, but I think simpler solution is to add following line:
DEFINES -= UNICODE
to your .pro file.

Much cleaner indeed. This does mean you have to add it to every project though (or have a .pri file where you store such settings if they’re common).
