[Insight-users] _TIFFerrorHandlerExt already defined in vtktiff.lib

[Dženan Zukić]

Thanks for the hint Sean.

itk_tiff_mangle.h contains definitions such as these:
#define _TIFFerrorHandler itk__TIFFerrorHandler
#define _TIFFwarningHandler itk__TIFFwarningHandler
and VTK version does the same just with vtk_ prefix.

However, neither files mentions the offending symbols, _TIFFerrorHandlerExtand
_TIFFwarningHandlerExt.

However, the command at the top of those files gives a hint that a
generation of these _mangle.h files is somehow faulty:
/*
This header file mangles all symbols exported from the tiff library.
It is included in all files while building the tiff library.  Due to
namespace pollution, no tiff headers should be included in .h files in
VTK.

The following command was used to obtain the symbol list:
*nm libvtktiff.a |grep " [TRD] "*
*/

Since I know nothing about internals of TIFF library nor about the
generation process of those files, I am pretty crippled when it comes to
solving this issue. Any help will be appreciated.

Regards,
Dženan
