[Insight-developers] SmartPointerForwardReference Compile error with mingw

[Luis Ibanez]

Hi Brad,

Thanks for the explanation.

I guess then that that right solution is to export
the explicit instantiation in the .cxx file.

Is that right ?

It is still unclear to me why this is only a problem
in MinGW, and not in other builds....



   Thanks


      Luis
