[Insight-users] Cmake Linking Object Error: undefined reference

[Abayiz]

Hello Cagatay,

Thank you for your reply. 


I found the problem was in the ".txx" file, one sentence was incorrectly written in the function definition. So it worked now. 


Thanks again,
Abayiz

Hi Abayiz, 

The difference that Bill suggested is the line:ADD_EXECUTABLE( VavSegment VavSegment.cxx)

If you have the headers and includes properly setup, this 
is the easiest way to add an executable. Please take a 
look here and make sure you have a similar include, 
define and ifndef setup both at the header and the hxx 
file as well as the templates and such before your 
implementation in the hxx files. Without seeing your 
code it is impossible to enumerate all the things that could 
be going wrong.

Let us know,

I've done this kind of work before, and they worked quite well, but when I did it exactly the same manner again, it failed.
