Wszystko działa, z wyjątkiem tego niezdefiniowanego błędu symboli:

bash-3.2$ make
g++ -Wall -g solvePlanningProblem.o Position.o AStarNode.o PRM.o PRMNode.o Worl.o SingleCircleWorld.o Myworld.o RECTANGLE.o CIRCLE.o -o solvePlanningProblem

To taki dziwny błąd. Czy coś jest nie tak z konstruktorem lub destruktorem? Wszelkie porady pomogą.

Po dodaniu {} po wszystkich konstruktorach i destruktorach błąd został zredukowany do:

Undefined symbols:
