Hi, I guess you are reading MPG for Gecode 4.* while using a Gecode version 3.*. Please make sure that the documentation and the Gecode version matches (MPG says on the second page to which Gecode version it corresponds to; you can find out the Gecode version you have installed by running any example with -help on the commandline).
