我用 rustup-init.exe 在 Windows 10 机器上安装了 Rust - Rust Book中推荐的方法.安装程序告诉我 Rust 需要 VS2013 或更新版本的 C 运行时。我安装了 VS2017，我假设 Rust 还不支持 VS2017，所以同意安装 C-runtime。安装成功。

main.rs:

fn main() {
    println!("Hello, world!");
}

编译:

> rustc main.rs
error: linking with `link.exe` failed: exit code: 1

          Try '/usr/bin/link --help' for more information.

error: aborting due to previous error

link.exe LIBPATH arg 指定了两次。

这是怎么回事？

> rustc --version
rustc 1.17.0 (56124baa9 2017-04-24)

最佳答案

作为rustup documentation说:

As mentioned on the Rust download page, there are two ABIs in use on Windows: the native (MSVC) ABI used by Visual Studio, and the GNU ABI used by the GCC toolchain. Which version of Rust you need depends largely on what C/C++ libraries you want to interoperate with: for interop with software produced by Visual Studio use the MSVC build of Rust; for interop with GNU software built using the MinGW/MSYS2 toolchain use the GNU build.

您已经安装了 MSVC 工具链。但是，您在命令 shell 中运行编译器，其中 link.exe 不指向 MSVC 链接器，而是指向 GNU 工具链——MSVC 不调用它的链接器 /usr/bin/link 或使用像 --help!

您应该配置您的 shell，使 MSVC 链接器在 PATH 中最重要，或者如果这是您的目标，则切换到 GNU ABI。

比较两者的帮助输出:

$ link --help
    Usage: link FILE1 FILE2
      or:  link OPTION
    Call the link function to create a link named FILE2 to an existing FILE1.

          --help     display this help and exit
          --version  output version information and exit

   For help on Linker, type `link /link' or `link'
   For help on Library Manager, type `link /lib' or `lib'
   For help on Dumper, type `link /dump' or `dumpbin'
   For help on Editor, type `link /edit' or `editbin'
   For help on CvtCIL, type `link /cvtcil'

I assumed Rust doesn't support VS2017 yet

它支持 VS2017 就好了；如 the 1.17 release notes 中所述，问题是它cannot automatically find the MSVC installation due to changes in where MSVC installs .从具有适当环境的 shell 内部运行 Rust 编译器工作正常。
