No need to run make again. Compilaton was already successful for this 
module. Otherwise it would have shown up in the error list.

You cannot run individual GRASS modules unless the environment is set up 
to include the necessary paths to libraries, etc.

So, you have to either run the grass71 startup script (grass71svn.bat or 
similar), which sets up the environment, and then run i.segment. Or you 
have to set up the environment manually [1].

I recommend you stay with the first solution, for now.
