在 Debian、libc6 上升级到 gcc-4.8 后 g++ 链接器错误 [英] g++ Linker errors after upgrading to gcc-4.8 on Debian, libc6

问题描述

我刚刚对 Debian Weezy 机器进行了 dist 升级，以便从 gcc-4.7 运行 gcc-4.8.以前的构建环境是健全的，并且可以正常编译.现在它给出了以下链接器错误，任何程序(甚至是微不足道的 hello world):

我确定这是与 libc6 相关的简单内容，但我看不出是什么?看到这个错误我很惊讶，因为我假设 dpkg 会处理任何依赖项，所以我不确定这个特定系统是否有问题或 debian 包有问题(这似乎不太可能，因为似乎没有其他人有这个问题！)

有什么想法吗?:)

解决方案

啊！写完这个，作为最后的尝试，我尝试了:

apt-get install libc6-dev --reinstall

(虽然我确信我之前已经这样做了)，你瞧，问题就解决了！

I have just dist-upgraded a Debian Weezy machine to run gcc-4.8 from gcc-4.7. Previously the build environment was sane and was compiling normally. Now it gives the following linker errors, with any program (even a trivial hello world):

collect2: error: ld returned 1 exit status

I'm sure this is something simple connected with libc6, but I can't see what? I'm quite surprised to be seeing this error since I'd have assumed dpkg would have taken care of any dependencies, so I'm not sure if it's something wrong with this specific system or an issue with the debian package (which seems unlikely, since nobody else seems to have this problem!)

Any ideas? :)

解决方案

Ah! As soon as I finished typing this, as a last ditch, I tried:

apt-get install libc6-dev --reinstall

(although I was convinced I'd already done it previously), and lo and behold, the issue went away!
