    Are we talking about a static library or a shared library? If so you will have to export symbols as loladiro said.[/quote]

      You might use the nm tool to see which symbols are exported from your library.

        Are you trying to mix MSVC and MinGW-compiled code? Not a good Idea!!

              [quote author="loladiro" date="1313072534"]You are not exporting the class.
              If you are using Qt Creator, have a look at the library template.[/quote]

              I read the qMake Project Files section "Declaring Other Libraries" and don't see what I haven't done correctly.

              Is this a QT tool I don't see it anywhere

                Again, did you compile your library with mingw? It doesn't seem that way because mingw static library files have a .a extension. You cannot mix MSVC and MinGW.

                  ah i see. so i'd have to use the MinGW in visual studio to build a library.

                    You'd have to either build both the library and app with MinGW or both with MSVC.

                      nm comes with MinGW, which is part of the Qt SDK. Just open a Qt command promt and type nm <binary> to get a list of exported symbols.

                      (Although it comes with MinGW it should work with any PE - read MSVC - binaries).
