我想在我的 Debian squeeze 64x 上使用 gcc 4.7.2
我按照该线程中的说明进行操作：获取 debian 的最新 gcc 吗？，但我收到错误，我尝试了几个 apt-get install 命令
只要我可以使用新的 c++ 11 功能，我就会选择 4.7.1。
以下是我更新的源列表和首选项文件。更新这些文件后，我从根终端使用 apt-get update 。
/etc/apt/sources.list

看起来这有帮助，但现在 apt-get 抱怨未满足的依赖关系

我如何解决这些未满足的依赖关系？
答案1
gcc-4.7.2 已于 3 天前的 9 月 20 日发布。它还不会进入 Debian 存储库（参见 update2，谢谢 derobert）。
根据发行说明它是一个错误修复版本，因此可能会使用与之前的 4.7.1 版本相同的库版本。因此，由于 4.7.1 位于存储库中，因此安装它以排序所有依赖项，然后如果您真的真的需要最新版本，请下载源代码并按照以下说明进行编译海湾合作委员会网站。
更新：
您的 source.lst 似乎有问题。作为解决方法，请尝试下载软件包这里并使用安装dkpg -i gcc_4.7.1-1_amd64.deb。
更新2：
正如 @derobert 下面指出的，4.7.2 确实在实验性仓库中。因此，请调整来自您链接到的帖子：
你的/etc/apt/sources.list应该看起来像这样：
德布本地.debian.镜像挤压主要 德布本地.debian.镜像主要不稳定
而你的/etc/apt/preferences应该看起来像这样：
包裹： * 引脚：释放 n=挤压 引脚优先级：900 包裹： * 引脚：释放 n=不稳定 引脚优先级：200
然后使用安装apt-get install gcc-4.7/unstable。
正如乔丹和您提到的原始教程一样，这不是一个好主意。完成后，请确保将您的来源恢复到稳定状态。
