g++ — 缺少数组头

Question

The following simple code can't be compiled by g++ 4.3:

#include <array>

using namespace std;

int main()
{
    std::array<int, 8> myarray;

    return 0;
}

array: No such file or directory

Also, the compiler doesn't seen to understand option '-std=c++11' as is recommended to provide to the compiler. Is there another option?

Thanks.

Answer 1

GCC 4.3 and presumably also your C++ library are too old for the support you're looking for. You need a newer version. Here's a link to the GCC C++11 support page , and another link to the libstdc++ C++11 support page .

Alternatively, clang supports all of C++11 with libc++ .

Answer 2

对我来说，问题是它是一个交叉编译器，需要被告知--sysroot=<path to sysroot>在哪里，并且提供--sysroot=<path to sysroot>允许 GCC 找到头文件
