[Insight-users] Problem with readers / writers in debug mode

[Luis Ibanez]

Hi Ivan,

You are probably mixing libraries from two different
compilation modes (Debug/Release), this may happen
if your have DLLs lying around in your path.

Didn't you get a warning/error message at the moment
of linking your executable ?

If so, please post that message to the list.


   Regards,



      Luis
