[Insight-users] Linkage errors concerning Watershed Filter

[Luis Ibanez]

Hi Zhao,

You seem to be mixing .obj modules compiled for Debug
with othere modules compiled for Release.

Please recompile all your libraries and .obj for the
same compilation mode.

You could avoid this basic problems if you use CMake
for configuring your projects.


Regards,


   Luis
