Symbol referencing errors

Hali
Az a gondom lenne, hogyha gcc-vel probálom lefordítani a porgramomat a következő hibát kapom:

dmake -m serial -f "/export/home/tiger/Documents/dice/Makefile-gcc-solaris-x86"
mkdir -p GNU-x86-Solaris
g++ -g -c -o GNU-x86-Solaris/test.o test.cpp
g++ -g -c -o GNU-x86-Solaris/trpg_dice.o trpg_dice.cpp
g++ -g -o GNU-x86-Solaris/dice GNU-x86-Solaris/test.o GNU-x86-Solaris/trpg_dice.o
Undefined first referenced

Van vkinek ötlete, hogy hol lehet a baj?
