Need help with compiling on Windows

[wysota]

Hm, yes. That approach is probably a lot easier. A problem that still remains though is that the library has to be installed on every machine where the project is being developed.

Not really. You can compile it in statically into your application.

In any case, I would still like to understand what this compiler error is that I'm seeing. What does it mean by dllimported class?

That's because of one of those stupid Windows macros. It'll be best if you google for "dllimport" and "dllexport" but before you do, try removing the QGLVIEWER_EXPORT macro from every class declaration or make sure the macro is empty (you'll have to find where it is defind and rem it out). This should be enough to make it build.
