[Insight-users] ITK from cvs compiled fine with gcc version 3.3.1 but not with gcc version 3.4.1

Hi Jens,


I already overcome  that kind of error by simply
change the member function in itkEventObject.h
classname(const Self&) from private to public

The next error I hit is:

when compile

c++ -o itkOctreeNode.o -DITKCommon_EXPORTS -fpermissive  
-ftemplate-depth-50 -fPIC  ...

I got

More tips ?

Thanks
