小米AX6/AX3600安装libstdcpp6

首先解锁路由器ssh功能，教程网上很多

更新opkg源：

src/gz openwrt_base http://downloads.openwrt.org/snapshots/packages/aarch64_cortex-a53/base
src/gz openwrt_luci http://downloads.openwrt.org/snapshots/packages/aarch64_cortex-a53/luci
src/gz openwrt_packages http://downloads.openwrt.org/snapshots/packages/aarch64_cortex-a53/packages
src/gz openwrt_routing http://downloads.openwrt.org/snapshots/packages/aarch64_cortex-a53/routing

执行opkg update

尝试安装speedtestcpp，报错找不到libstdcpp6，官方源里面没有

在Openwrt官网snapshots里找到：

https://downloads.openwrt.org/snapshots/targets/ipq807x/generic/packages/libstdcpp6_12.3.0-4_aarch64_cortex-a53.ipk

下载至路由器本地安装：

root@XiaoQiang:/tmp# wget https://downloads.openwrt.org/snapshots/targets/ipq807x/generic/packages/libstdcpp6_12.3.0-4_aarch64_cortex-a53.ipk
