Question

我试图在linux服务器上利用C ++ 11的库编译一些代码。代码在我的mac上用我的makefile中的这一行编译好：

 CC = clang++ -std=c++11 -stdlib=libc++

但是，当我尝试在Linux服务器上使用gcc版本4.8.1编译相同的代码时，我收到以下错误：

看来问题是标题。当我在这里看https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.200x时，在＆＃34; 26.5＆＃34;，看来gcc 4.8.1不支持随机数生成，除非我不正确地解释这一点。我该怎么编译这个文件？

使用gcc 4.8.1编译C ++ 11＆＃39; <random>的问题
