无法在Windows 10中构建wasmtime

Question

我尝试在Windows 10中构建wasmtime，但失败。

运行命令cargo build --release后，出现错误消息：

Done Building Project "G:\wasi\wasmtime\target\release\build\wasmtime-wasi-628aff801f2e5951\out\build\SandboxedSystemPrimitives.vcxproj" (default targets) -- FAILED.
Done Building Project "G:\wasi\wasmtime\target\release\build\wasmtime-wasi-628aff801f2e5951\out\build\ALL_BUILD.vcxproj" (default targets) -- FAILED.
Done Building Project "G:\wasi\wasmtime\target\release\build\wasmtime-wasi-628aff801f2e5951\out\build\install.vcxproj" (default targets) -- FAILED.

Build FAILED.

找不到sys / ioctl.h和pthread.h文件。

我已安装MinGW，CMake和LLVM。我需要安装其他与Linux相关的工具来构建它吗？

Wasmtime的WASI实施曾经只支持POSIX系统，但是前一阵子已经改变了。您现在应该可以在Windows上构建Wasmtime，而不会出现问题。

或者，您也可以使用downloading the installer使用预构建的二进制文件。
