I have a library that uses QT. The library was staticly linked with QT. I am now using this library in another application (exe) that also uses QT. The problem I am having is when I compile I receive a large number of Linker re-definition errors.

My assumption was that by static linking the QT libs in my library I would avoid this.

How can keep these methods from being exported. Is a def File the answer?
