由于Impure Library导致Debian 9.2错误

Question

我在Debian 9.2系统上使用the instructions in the documentation安装了Rust，并尝试使用compile the hello world example。编译失败，出现以下错误：

$ rustc main.rs --verbose
error: linking with `cc` failed: exit code: 1

以下是在我的系统上运行uname -a的输出

Linux localhost 4.9.0-4-amd64＃1 SMP Debian 4.9.51-1（2017-09-28）x86_64 GNU / Linux

我在谷歌上尝试了以下搜索，但似乎找不到任何有用的东西：

• rustc和ld-wrapper：错误：尝试使用不纯的库
• rustc AND ld-wrapper：错误：尝试使用不纯的库“/usr/lib/gcc/x86_64-linux-gnu/6/libgcc_s.so”
• rustc AND错误：与cc链接失败：退出代码：1

Debian 9.3是最新的，但这可能比Debian的测试要少于Ubuntu。

在Ubuntu Xenial上，安装/编译方向对我来说很好。

你似乎碰到了一个没有很好记录的角落案例，其中一对引用是相关的：

...尝试使用不纯的库，错误消息

包装器的目的是检查传递给链接器的@code {-L}和@code {-l}开关，添加相应的@code {-rpath}参数，并使用这组新参数调用实际的链接器。默认情况下，链接器包装器拒绝链接到商店外的库以确保“纯度”。使用工具链链接本地库时，这可能很烦人。要允许引用商店外的库，您需要定义环境变量@code {GUIX_LD_WRAPPER_ALLOW_IMPURITIES}。

这段代码：

https://lists.gnu.org/archive/html/help-guix/2016-12/msg00040.html

...为了将来参考，攻击haskell包这些步骤：

...导出GUIX_LD_WRAPPER_ALLOW_IMPURITIES = y ...

如果GUIX甚至与您的情况相关，那么定义它可以让您在安装过程中更进一步。
