1.下载
镜像站点：https://gcc.gnu.org/mirrors.html
速度还不错的：ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/
2.解压安装依赖库
./contrib/download_prerequisites
3.配置
./configure --disable-multilib（不生成编译为其他平台可执行代码的交叉编译器）
4.编译安装
make && make install
5.测试代码
#include <iostream>
#include <string>
#include <iterator>
#include <algorithm>
#include <array>
int main()
{
// construction uses aggregate initialization
std::array<int, 3> a1{ {1,2,3} }; // double-braces required
std::array<int, 3> a2 = {1, 2, 3}; // except after =
std::array<std::string, 2> a3 = { {std::string("a"), "b"} };
// container operations are supported
std::sort(a1.begin(), a1.end());
std::reverse_copy(a2.begin(), a2.end(),
std::ostream_iterator<int>(std::cout, " "));
std::cout << ‘\n‘;
// ranged for loop is supported
for(auto& s: a3)
std::cout << s << ‘ ‘;
std::cout << ‘\n‘;
}
如果出现如下报错：
/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21‘ not found (required by ./test)
更新软连接即可：
/usr/lib64/libstdc++.so.6 -> /usr/lib64/libstdc++.so.6.0.21
