[Insight-users] Problems when using itk with another C++ tool kit

[Dalal, Dhaval]

Hi Luis
I got this problem fixed.
Dcmtk by default is compiled with /GR- option.
When Linked with ITK, it generated the following warning 
 C4541: 'dynamic_cast' used on polymorphic type 'itk::EventObject' with 
 /GR-; unpredictable behavior may result 
I recompiled my code with the /GR flag option set and it compiled clean when
i linked it again with itk (since itk is also compiled with this flag set).

Thanx

Regards
Dhaval

Hi Dalal, 

Please post the CMakeCache.txt file that CMake 
generates in the binary directory of your project. 



   Thanks 



      Luis
