[Insight-developers] GetInverseTransform - MSVC 6 instantiation bug

[Tom Vercauteren]

Hi all,

The dashboard is giving me the following error on visual 6 compiler:

c:\Dashboards\My
Tests\InsightContinuous\Code\Common\itkTransform.h(120) : error C2027:
use of undefined type 'Transform<double,3,2>'

        c:\Dashboards\My

Can anyone help me understand what this means?

I initially thought that this might be related to explicit
instantiation since itk::Transform<double,3,2> is not listed in:
http://www.itk.org/cgi-bin/viewcvs.cgi/Wrapping/ExplicitITK/Modules/Common/wrap_itkTransform.cmake?root=Insight&sortby=date&view=markup

Note that I am not even sure that wrap_itkTransform.cmake is the
correct file to look at since I have never worked with explicit
instantiations within ITK before and since I can't manage to compile
ITK with explicit instantiations turned on on my machine.

Also it seems that dash13 is not using  explicit instantiations:

Thanks for your help.
