So I've seen a lot of similar forum posts, tried a few things, but still haven't found an answer. When I try to compile these examples (Windows, default install options), I get loads of "undefined reference to '_imp__ZN....'" errors. I've tried commenting out the symbian: include($$QT_SOURCE_TREE...) line in the project file. I've tried run qmake, build all, rebuild all, clean all in various orders. No dice. I must be missing something pretty basic - none of the examples compile. Can somebody point me in the right direction?
