Passing Dynamic Array to function

Question

What is an undefined reference/unresolved external symbol error and how do I fix it?

I am passing a dynamic array of integers to a function and I can't get it to work.

int * tempP1;

tempP1 = new int [numP1+1];

Call:

Polynomial P1(numP1, tempP1);

Prototype:

Polynomial(int tempNum, int * tempPoly);

Function:

Polynomial::Polynomial(tempNum, int *tempPoly)

Error:

Undefined symbols for architecture x86_64:
  "Polynomial::Polynomial(int, int*)", referenced from:
     _main in ccDOuaGg.o
  "Polynomial::~Polynomial()", referenced from:
     _main in ccDOuaGg.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

Any help would be much appreciated :)

baah, it's the problem with arrays, not with externals @Luchian — Bartek Banachewicz, Sep 27 '12 at 10:03
@BartekBanachewicz what arrays? The problem is that the constructor/destructor aren't implemented. — Luchian Grigore, Sep 27 '12 at 10:04
In the definition of the `Polynomial` constructor you are missing the type for the first argument, copy-paste error? — Some programmer dude, Sep 27 '12 at 10:04
"passing a dynamic array of integers to a function" using C-style pointers. Meh. — Bartek Banachewicz, Sep 27 '12 at 10:04

I figured out the problem. I was compiling this program wrong way.
