我在我的电脑上下载并安装了Rust和Cargo的夜间版本，并使用Cargo生成了一个新的二进制项目:
Cifram@Valyria ~
$ cargo new test --bin
然后我尝试使用全新、未受污染的 Rust 和 Cargo 安装来运行这个新项目，但是出现了以下错误：
Cifram@Valyria ~/test
$ cargo run --verbose

我不确定为什么rustc在调用gcc，因为我理解它是基于LLVM构建的。我确实安装了通过MinGW安装的gcc，所以我的第一个想法是可能那个gcc安装正在干扰。

这是gcc的最新版本。但是，它可能不是rustc所期望的版本。因此，我从我的路径中移除了C:\MinGW\bin并再次尝试，结果如下:

好的，这是一个略有不同但并不更好的错误。相同的gcc命令失败了，但是，在此之前的错误是：
C:\cygwin64\home\Cifram\test\target\test.o: file not recognized: File format not recognized
现在它是：
ld: this linker was not configured to use sysroots
我并不认为这两个都非常有意义。我尝试直接运行"rustc main.rs"。得到了相同的错误（除了它是“src\main.o”而不是“target\test.o”）。尝试在本机Windows命令行上完成所有操作，而不是使用cygwin。相同的错误。所以似乎不应该归咎于Cargo或cygwin。我还尝试下载Rust的最新“稳定”版本（0.12.0），但仍然遇到了相同的错误。我已经搜索了这些错误，但没有结果。所以我开始失去主意。
需要帮助吗？
