[Insight-users] Compiling error (Linking error): ITK

Thu Aug 3 22:12:26 EDT 2006

Amitesh,

This is a little bit confusing because your previous message shows an
error in line 279 of imageprocessing.cpp:
/home/amitesh/work/gui/imageprocessing.cpp:279: undefined reference to
`IntensityManipClass< unsigned short>::IntensityManipClass()', but the
file you sent has only 131 lines. I assume you have been debugging and
sent a more recent copy.

Either way, I believe the problem is that your IntensityManip class is
templated, so you should not compile it on it's own. It needs to be
compiled when the type is known. For example, you might have an
IntensityManipClass<int> and an IntensityManipClass<float>, so it
would actually need to be compiled twice, once for each type, inside
of the class that uses it (imageprocessing.cpp).

The easiest (but not the best style) way to do this is to put
IntensityManip.cpp inside of IntensityManip.h, and remove it from your
Makefile. This was probably just an oversight, but if you are not
familiar with templates, I suggest you experiment with this without
ITK in order to reduce the complexity of the code and the error
messages.

Please write if this does not solve your problem,
michael
