[vtkusers] ESP value error when including file using WXWidget library

[REGAT-BARREL Aurélien]

Which version of VC++ do you use ?

specific to MSVC++.

The same error occurred for me using VTK with FLTK, but was not 
directly related to either toolkit. Instead, the error was produced by 
non-member functions used as callbacks to vtkProcessObject progress 
events. The problem was eliminated by the switch to use of vtkCommand 
functors. Without special Microsoft C++ extensions garbage, I think the 
runtime environment sees global callback functions as C calls and is 
unable to use them since they were compiled as C++. Without resorting to 
uglifying your source with '__cdecl' (or something else?), simply making 
your callbacks static members of a class might eliminate the "ESP" error.

Also consult the evil empire itself:
