[Insight-users] Linking Error vtkITKMutualInformationTransform in vtkITK Project

[alqatarneh at netscape.net]

Hi Luis, Hi all,

I got the following error while compiling the Insight Applications.
I was trying to compile and link the vtkITK Application while also creating executables for vtkITKMutualInformationTransform  and vtkITKNormalizeImageFilter.
So that they can be used for the tcl script DemoMutual.tcl.

Any help would be highly appreciated!
Regards,
Sharef

The error I got is:
 --------------------Configuration: vtkITKMutualInformationTransform - Win32 RelWithDebInfo--------------------

MSVCRT.lib(crtexe.obj) : error LNK2001: unresolved external symbol _main
