我嘗試在gcc 6.0的開(kāi)發(fā)中實(shí)際使用新的c ++ 1z功能。如果我嘗試這個(gè)小例子：#include <iostream>#include <experimental/filesystem>namespace fs = std::experimental::filesystem;int main(){    fs::path p1 = "/home/pete/checkit";    std::cout << "p1 = " << p1 << std::endl;}我有：/ opt / linux-gnu_6-20151011 / bin / g ++ --std = c ++ 1z main.cpp -O2 -g -o go/tmp/ccaGzqFO.o：在函數(shù)\`std :: experimental :: filesystem :: v1 :: __ cxx11 :: path :: path（char const（＆）[36]）'中：/opt/linux-gnu_6-20151011/include/c++/6.0.0/experimental/bits/fs_path.h:167：對(duì)`std :: experimental :: filesystem :: v1 :: __ cxx11 :: path :: _ M_split_cmpts的未定義引用（）”collect2：錯(cuò)誤：ld返回1退出狀態(tài)gcc版本是快照l(shuí)inux-gnu_6-20151011有什么提示如何鏈接新的c ++ 1z功能嗎？
