Hi Fanouris,

I was getting this error when compiling GridFlow 0.8.4 as well.

The solution was to copy the entire commandline that invokes the 
compiler, paste into Text Edit or some such and change the instance of 
"-undefined suppress" to "-undefined error" and copy-paste it back in 
your Terminal window. That's what worked for me.. Note that it doesn't 
work to change "-undefined suppress" in the Makefile or Makefile.in 
because some other components of GridFlow must explicitly require 
"-undefined suppress". Good luck! P.S. I'm on 10.3.9 so I'm not sure 
how different the process is but I don't imagine it is very much.
