oredered_set 未在 C++ 中编译

Question

我编写了此语句并收到编译错误。 代码：

#include<bits/stdc++.h>
#define ll long long
#include <ext/pb_ds/assoc_container.hpp>
#include <ext/pb_ds/tree_policy.hpp>
using namespace std;
using namespace __gnu_pbds ;
template <typename PB>
using ordered_set = tree<PB,null_type,less_equal<PB>,rb_tree_tag,tree_order_statistics_node_update> ;
int main()
{
    ordered_set s;
    s.insert(5);
}

据我所知，我在这里没有犯任何错误。但我收到此错误消息。

Answer 1

我怀疑你有一个名为

c:\mingw\lib\gcc\mingw32\6.3.0\include\c++\ext\pb_ds\detail\resize_policy\hash_standard_resize_policy_imp.hpp0000644

的文件。重命名该文件以删除其末尾的

0000644

。

Answer 2

更新您的 MinGW 版本或检查您在 env 中包含正确的路径。如果仍然不起作用，请检查“hash_standard_resize_policy_imp.hpp”该文件是否存在，如果不存在，则将其添加到“**c:\mingw\lib\gcc\mingw32 .3.0\includ”
