I'm was trying out vectors (I am going to use them in a program that I
am currently writing).  Everything seemed to be going great until the
"LD" phase of compiling, at which point I get this (and a bunch more
off screen):

reference to `__default_alloc_template<false, 0>::_S_start_free'

collect2: ld returned 1 exit status

Possibly it is missing a function? (__default_alloc_template<false,
0>)

Here is my code (although I'm not sure it'll help, seeing as there
doesn't seem to be anything wrong with the compiling phase...it seems
to be the linking phase):

#include <stdio.h>
#include <vector>

int main(int argc, char *argv[])
{
	printf("STL Test #1: Using Vectors");
	vector<int> i(0);
	if (i.empty())
	{
		printf("\n\ri is empty.");
	}
	else
	{
		printf("\n\ri has %i elements in it.", i.size());
	}
	i.insert(0,3);
	i[0] = 1;
	i[1] = 2;
	i[3] = 3;
	if (i.empty())
	{
		printf("\n\ri is empty.");
	}
	else
	{
		printf("\n\ri has %i elements in it.", i.size());
		for (int k = 0; k < 3; k++)
		{
			printf("\n\ri[%i] = %i",k,i[k]);
		}
	}
	
	return 0;
}


Thanks for your help :)
