[Insight-users] warning in insightoolkit-2.8.1

[Luis Ibanez]

Hi Knoppix,


This is a very common warning in Visual Studio.

Their debugger cannot manage symbols larger than 255 characters.

Most STL symbols surpass that limit, and that results in many
annoying warning from Visual Studio.

Solutions:

1) Silence the warning with the pragma:

      #if defined(_MSC_VER)
      #pragma warning ( disable : 4786 )
      #endif


    OR

2) Do not compile for debug   :-)


    OR


3) Get rid of Windows and install Linux  :-)
    GCC does not have those nearsighted limitations.



Regards,


     Luis
