没有匹配函数调用“查找”

我有以下代码：没有匹配函数调用“查找”

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

using namespace std; 

int main() 
{ 
    typedef vector<int> IntContainer; 
    typedef IntContainer::iterator IntIterator; 

    IntContainer vw; 

    IntIterator i = find(vw.begin(), vw.end(), 5); 

    if (i != vw.end()) 
     { 
     printf("Find 5 in vector\n"); // found it 
     } 
     else 
     { 
      printf("Couldn't find 5 in vector\n"); // couldn't found it 
     } 

    return 0; 
}

我尝试用gcc 4.7.1编译它在Ubuntu并得到以下错误：

vec_test.cpp: In function ‘int main()’: 
vec_test.cpp:27:46: error: no matching function for call to ‘find(std::vector<int>::iterator, std::vector<int>::iterator, int)’ 
vec_test.cpp:27:46: note: candidate is:

vec_test.cpp:27:46: note: ‘__gnu_cxx::__normal_iterator<int*, std::vector<int> >’ is not derived from ‘std::istreambuf_iterator<_CharT2, std::char_traits<_CharT> >’

此代码不执行任何操作，因为矢量未用任何内容初始化，但应编译。

我怀疑这是一个海湾合作委员会的问题，但经过大量的挖掘我绝望地退出。请让我知道如果有人遇到这个问题，并知道如何解决它。

我怀疑Orit是否有你没有的gcc问题:) – Nitay 2013-03-07 12:07:11

也许某个文件定义了一个函数在全局命名空间中找到？

您是否试过指定全范围？也就是说，std ::找到而不是找到。它可以帮助deleting that weird line：

using namespace std;

但是，这不是我所期望的。我会称它为一个错误。
