I created a default Gui project (mo modifications whatsoever) and, using Creator, confirmed that it compiled and linked. (Dynamic linkage to QT libs).
I then opened a cmd prompt. Set my environmental variables to the various Qt bin dirs, then ran qmake and mingw. I get an odd linker error.
I've checked other posts with this problem and in their cases it turned out to me a mingw version problem. In my case I only have the mingw that was installed by QT Creator.
The error is below.
Do you have any idea why the cmd line compile fails in my case?
