[Insight-users] A problem with compilation...

[Luis Ibanez]

Hi BeeJay,

Thanks for sending the full description of your
problem, including the error messages.

Since you are moving the Image2.cxx example
to an independet folder and creating your own
CMakeLists.txt file, the only thing missing is
the ITKIO library in the TARGET_LINK_LIBRARIES()
command.

Your CMakeLists.txt file says:

 > TARGET_LINK_LIBRARIES(Image ITKCommon)

but it should be:

 > TARGET_LINK_LIBRARIES(Image ITKIO ITKCommon)

The ImageIO classes are defined in the ITKIO
library.

Please look first at the tutorial sessions in

     http://www . itk . org/HTML/Tutorials . htm

in particular to

http://www . itk . org/CourseWare/Training/GettingStarted-I . pdf



Regards,


    Luis
