undefined reference to class members

[Nobody/Anonymous]

I'm trying to program something using apstring.h and dice.h (which also includes randgen.h).  I placed these and their corresponding .cpp files in my /include directory, but I'm getting the following linker errors:

c:\my documents\programs\arpg\combat.o(.text+0x4d):combat.cpp: undefined reference to `Dice::Dice(int)'
c:\my documents\programs\arpg\combat.o(.text+0x5e):combat.cpp: undefined reference to `Dice::Dice(int)'

c:\my documents\programs\arpg\combat.o(.text$_$_10characters+0x15):combat.cpp: undefined reference to `apstring::~apstring(void)'

I have absolutely no idea what this implies.  Does anyone know how to fix it?

Sorry about the double post. I should've realized when IE said that I needed to resend information that it would re-post my topic...

these are linking errors:
your module combat, can not linked correctly, because the linker doesn't have/find the module/lib where Dice is coded. 
Either Lib is missing, or compilation of Dice has failed.
