[Insight-users] Help with "Undefined references during linking"

[Martin Kavec]

Hi,

I am writing a piece of IO code to read a FSL affine transform file. The 
transform is (always) stored in an ASCII file as a 4x4 matrix, so it is 
should not be a "rocket science" to read it.

My code is based on Code/IO/itkTransformFileREader.cxx, except that 
the ::Update() method will be different. I attached the header, 
implementation, CMakeList.txt and small test code to make it easier to 
compile.

The code compiles fine, but the linker complains about missing references 
to ::Update(), ::New() and ::Create() methods.

I tried to figure out what's wrong, but no luck, so I would appreciate a help. 
Thanks.

Martin
