[Paraview] Not a valid QT plugin on windows

[Moreland, Kenneth]

The depends command (provided by MSVC) provides information on one dll both about the other libraries it depends on and the symbols (variables and functions) that it exports.  I believe the information is at the right at a bit below center in the GUI.  For a ParaView plugin, there are typically only one or two functions exported that provide the hooks to allow ParaView to load the plugin.

Ok,

I removed the EXPORTS macro in my header, and it produces the same as setting the flag vtkIO_EXPORTS. The library is still not loaded though. So now I'm looking at the dependencies and the Initialize function.

Kenneth, how do I go about "making sure that the server manager initialization function is properly exported" ? I'm not sure I really understand what you mean ?

Thanks
Jacques

That sounds similar to a bug that Pat Marion fixed for the Streaming
ParaView plugin under windows. His change that fixed it was this:

Index: Client/pqGlobalStreamingViewOptions.h
