QPluginLoader and Loading and Verifying Plugins Dynamically describe the checks that the plugin loader makes. Assuming the source code is good, you have either built the plugin against a different Qt version, the same version but a different Qt configuration, for a different architecture, or with a different C++ compiler from the one used for your Designer (name mangling differs by compiler).
