使用链工作C ++程序并且在不知道原因的情况下编译有问题。
我得到的错误是:
Undefined symbols for architecture x86_64:
"userInputOutput(linearList*, std::basic_string<char, std::char_traits<char>, std::allocator<char> >)", referenced from:
_main in ccBEoeAc.o
"chain::chain(int)", referenced from:
_main in ccBEoeAc.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
如果我使用g ++ -c main2.cpp,它会编译,但我想确保我不只是用这个选项覆盖一些东西。
Main2.cpp
#include <iostream>
#include "Chain.h"
#include "IOcode.h"
using namespace std;
int main (){
//Call constructor, initial capacity 10
chain *myChain=new chain(10);
//Print initial chain
userInputOutput(myChain, "chain");
}
Chain.cpp
#include "Chain.h"
#include <stdio.h>
#include <iostream>
#include <sstream>
#include "Myexception.h"
using namespace std;
chain::chain(int initialCapacity)
{
cout<<"This method is working"<<endl;
/* if (initialCapacity <1)
{
//throw illegalParameterValue();
}
firstNode=NULL;
listSize=0;
*/
};
IOcode.cpp
#include <iostream>
#include "Linearlist.h"
using namespace std;
void userInputOutput (linearList* l, string dataStructure){
for (int i = 0; i < 13; i++)
l->insert(i, i+1);
cout<<"The initial "<<dataStructure<<" is: ";
l->traverse();
cout<<"welcome to the assignmet 3!"<<endl;
while(true){
//do stuff
}
}
知道为什么我会收到这些错误吗? IOcode文件提供给我,我创建的chain.cpp。对不起,可怜的代码,C ++的新手。
答案 0 :(得分:4)
您只是在编译一个文件。
这对于快速而肮脏的尝试应该没问题:
g++ main2.cpp Chain.cpp IOcode.cpp
虽然我会添加-Wall -Wextra -pedantic -Werror
