如何在Debian Wheezy Armel上安装G++4.9？

Question

    deb http://security.debian.org/ wheezy/updates main
    deb-src http://security.debian.org/ wheezy/updates main
    deb http://ftp.us.debian.org/debian wheezy main non-free
    deb-src http://ftp.us.debian.org/debian wheezy main non-free

简单的apt-get安装程序包不起作用：

    root@arm:~#  apt-get install g++-4.9
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    E: Unable to locate package g++-4.9
    E: Couldn't find any package by regex 'g++-4.9'

根据这篇博文，另一个解决办法是从“Jessie”安装G++4.9包。简单地说，在安装新的G++时，您必须告诉APT使用Jessie repos。首先更新当前的喘息：

sudo apt-get update
sudo apt-get upgrade

然后进行备份：-）并编辑/etc/apt/sources.list，以便将字符串“Wheezy”替换为“Jessie”:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.WHEEZY
sudo vi /etc/apt/sources.list

现在更新软件包列表并安装GCC/G++4.9版本：

sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9

sudo cp /etc/apt/sources.list.WHEEZY /etc/apt/sources.list
sudo apt-get update
