我无法在 gcc 上构建我的应用程序，因为我使用各种 c++0x 功能。我使用的是 Debian 6 (Lenny)，升级/更新后我有 gcc 版本 4.4.5-8。我不确定需要哪个版本，但 mingw 4.6.2 可以工作。 gcc 4.7.0 已发布。
如何在 Debian 上安装 gcc 版本 4.6+？
答案1
Debian 6.0 是 Squeeze（目前稳定）； Lenny 是 5.0（目前是旧稳定版）。我假设你指的是挤压。
使用apt固定将 Wheezy（当前正在测试）安全地添加到您的 中sources.list，然后安装gcc-4.7/喘息。
换句话说，你的/etc/apt/sources.list内容应该是这样的：
德布本地.debian.镜像挤压主要 德布本地.debian.镜像气喘吁吁的主
而你的/etc/apt/preferences看起来应该是这样的：
包裹： * 引脚：释放 n=挤压 引脚优先级：900 包裹： * Pin：释放n=喘息 引脚优先级：200
（确切的数字并不重要；请参阅男人 5 apt_preferences有关不同范围含义的详细信息。）
这将防止无意中安装测试包。 （当然，您可以将整个系统升级到测试阶段。）
您可能会遇到一些解析错误，apt-get install gcc-4.7/testing因为它将具有需要高于稳定版本的依赖项；apt-get --target-release testing install gcc-4.7将在命令持续期间将测试设置为优先级 990。
答案2
向后移植到挤压/稳定是可能的，但并非易事。这是针对目录中文件的补丁debian，适用于4.7.0-1测试中的 Debian 源（也应该适用于不稳定的可能略有不同的版本4.7.0-3），并且应该允许成功地在挤压上构建，尽管我还没有直接测试该补丁将其应用于原始来源。显然，在稳定版上安装测试的二进制包是可能的，但一般来说不是一个好主意。这样做会导致不稳定，并且从一开始就违背了使用稳定的目的。但是，以这种方式向后移植不会强制进行任何额外的升级，并且不会给您的系统带来任何问题。
我不记得对 进行过更改rules.parameters，但补丁的其余大部分是我所做的更改，而不是机器生成的更改。尝试将此补丁应用到 Debian 源代码，然后运行debuild binary或类似的操作。如果有兴趣，并且从该消息获取补丁不方便，我可以将补丁上传到某个地方。欢迎报告成功和失败。
笔记：
- 这将需要安装一堆构建依赖项，但只能通过挤压安装，
并且apt-get build-dep由于构建依赖项已在本地更改而无法工作
- 您必须手动执行此操作。 - 的构建
libgcc1-dbg出现错误，所以我将其删除。 - 测试套件有一些问题，所以我禁用了它们。看线条
with_check := disabled by hand。问题不是测试失败，而是构建找不到与测试相关的一些文件，因此出现错误。 - 我替换
binutils成了squeeze中的版本，即binutils (>= 2.20.1)。 - 我禁用了
multilib，因为挤压不使用它。 - 此版本在 amd64 上测试过，但至少也可以在 i386 上运行。
