本文介绍了可疑的std :: array C ++ 11库被打破了？我该怎么办？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
从google我似乎找不到清楚的答案，但我不知道该怎么办。我怀疑在一个更大的程序可能有一个问题，我使用数组C ++ 11库为g ++编写并写了一个测试程序。我使用g ++ 4.8.1。
From google I can't seem to find clear answers, But I don't know what to do. I suspected there might be a problem in a larger program I was writing with the array C++11 library for g++ and wrote a test program. I am using g++ 4.8.1.
main.cpp：
#include <iostream>
#include <array>
int main()
{
std::array<int,5> vector;
return 0;
}
我的测试命令行编译是：
My test command line compile is:
g++ main.cpp -std=c++11
$ b
with errors..

很明显，从错误，有很多引用我std ::数组文件，我已经包括，似乎是错误的根源。
And clearly from the error, there is a lot of reference to the std::array file that i have included which seems to be the source of the error. What do I do?
编辑：添加编译命令和g ++版本。
Thanks in advance.
推荐答案
以某种方式出现一个拼写错误到OP的< array> 。应该有什么
Turns out somehow a typo made its way into OP's <array>. What should have been
template<typename _Tp, std::size_t _Nm>
struct array
{
成为
template<typename _Tp, std::size_t _Nm>
struct Array
{
导致一个bazillion编译器错误， < array> 的其余部分。
Causing a bazillion compiler errors as it tries to process the rest of <array>.
