我正在尝试遵循此处提供的说明：如何在 debian jessie 8.1 上安装 GCC 5

有什么问题以及如何解决它？

问题是什么？

gcc5通过apt使用该方法安装pining可能会破坏您的系统，因为在您的情况下有很多依赖项需要升级到testing.不幸的是，向后移植无法提供所需的软件包。

我该如何修复它？

您可以gcc-5.3.0通过安装linuxbrew（安全并在 Debian 稳定版 KDE 上经过测试）：

安装所需的包：

sudo apt-get install build-essential curl git python-setuptools ruby

安装linuxbrew：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install)"
PATH="$HOME/.linuxbrew/bin:$PATH"

编辑您的~/.bashrc以添加~/.linuxbrew/bin到您的路径：

echo 'export PATH="$HOME/.linuxbrew/bin:$PATH"' >>~/.bashrc

更新并安装最新的可用gcc版本：

brew update
brew install gcc

验证gcc版本：

#gcc --version
gcc (Homebrew gcc 5.3.0) 5.3.0
