[Insight-developers] compiling ITK with gcc 4.3

[Casey Goodlett]

The error I got was for example in itk::Neighboorhood

/home/gcasey/research/itk/Insight/Code/Common/itkNeighborhood.h:154:
error: declaration of 'unsigned int itk::Neighborhood<TPixel,
VDimension, TAllocator>::Size() const'
/home/gcasey/research/itk/Insight/Code/Common/itkSize.h:46: error:
changes meaning of 'Size' from 'class itk::Size<VDimension>'

The problem is that the new gcc enforces having duplicate names in the
same class being an error.  In the neighboordhood class itk::Size is
used and there is also a function named Size().  This generates an
error if the Size class is not qualified with itk.    This is
described in the "name lookup changes" section of the porting document
Sean mentioned http://gcc.gnu.org/gcc-4.3/porting_to.html  Also having
a typedef of a templated type to its own name without a template

typedef Size<3> Size;

is now enforced as an error.
