Hi Martin,

We just tried jour code snippet.

It works fine when the includes:

   #include "stdafx.h"
   #include "osirislight.h"
   #include "VtkItkConnector.h"

are commented out.

There should be a wrong usage of
namespaces inside one of these files.

Could you please post those files ?
or at least verify the namespaces
are used correctly inside.

One common error is to declare a namespace
and let it open (e.g. miss the closing bracket)

like:

namespace  MyOpenNamespace {

///....

// unmatching  -> }



----

Please find attached the CMakeList.txt file
and the variation of your code that we tested
here.

Thanks,


Luis
