[Insight-developers] Deriving from templates

[Bradley Wyman]

I have some code that inherits from a templated class as in:

template <class TInputImage, class TOutputImage, class ResamplerType>
class ITK_EXPORT BSplineUpsampleImageFilter :=20
    public ResamplerType
{
  ...

This works fine under VC++ but does not compile on Linux.  On Linux the
compiler throws errors elsewhere in the code such as:

parse error before `=3D'

on the seemingly unrelated line (in the txx file):
InputImagePointer  inputPtr =3D const_cast< TInputImage * > (
this->GetInput().GetPointer() );


Has anybody had experience compiling this type of templated code on
Linux?  When I hard code the "public ResamplerType" line all compiles
and works.  Since I have 4 ResamplerTypes I would prefer not to hard
code this as it would result in 4 nearly identical routines.
Suggestions are welcomed.
