[Insight-users] Using ITK in a Cocoa App (+Xcode)

Hi Oliver,

The two first compilation errors

InsightToolkit/Common/itkSmartPointer.h:129: error: expected ';'
before '(' token
InsightToolkit/Common/itkMacro.h:533: error: expected class-name
before '{' token

 are related to missing declarations of

  * std::ostream
  * std::ostringstream

Are you by any chance doing something like:


     using namespace std:


in your code ?


Also,

   I'm illiterate on Objective-C++      :-/

Could you please tell us if you are allowed to use
std::streams in an Objective-C++ file ?


     Thanks


            Luis
