Implementing A Plugin System in C or C++ [closed]

Answer 1

Qt provides QPluginLoader: http://qt-project.org/doc/qt-4.8/qpluginloader.html

If you need/want more fine grained control, Qt also provides a means to load libraries on the fly with QLibrary: http://qt-project.org/doc/qt-4.8/qlibrary.html

Even better, these are portable across platforms.
