我正在尝试使用基于链接列表的堆栈和队列，并收到以下错误：
Undefined symbols for architecture x86_64:
"stack::push(double)", referenced from:
Calculator::method1(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >) in Calculator.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [main] Error 1
#include "Calculator.h"
#include "queue.h"

#include <iostream>
#include <stdio.h>

int Calculator::method1(std::string eq)
{
stack s;
int size = eq.size();
for (int o = 0; 0 < size; size--)
{
if (isdigit(eq[o]))
{
double t = atoi (eq.c_str());
s.push(t);
}
else
{
queue q;
}
}
//std::cout << eq.size() << std::endl;
return 1;
}
这是我的make文件
