[Insight-users] ITK_TYPENAME

[Luis Ibanez]

Hi Mike,

ITK_TYPENAME is defined in

   Insight/Code/Common/itkWin32Header.h

in lines 74-80

This typedef was introduced in order to deal
with inconsistencies between several compilers
regarding the use of typename in the default
arguments of template parameters.

The fact that your compiler is not finding this
symbol may indicate one (or both) of the following
things:


A) _MSC_VER  is not being defined or is > 1310

B) your code is not including tikWin32Header.h


(A) is much more likely to be happening than (B).




You should NOT do

       #define typename ITK_TYPENAME

that will be catastrophic !!!

(I hope that's just a typo in your email).



You probably should try making just

    #define ITK_TYPENAME


since VC++ 6.0 just don't know nor care about
the "typename" keyword.


The real solution to your problem will be to figure
out if itkWin32Header.h is being included or not.


Regards,


    Luis
