android - 无法为 armv7-linux-android 目标执行 Rust 链接器

Question

我正在尝试将 Rust 项目编译*.so为 arm 的库。

货物.toml：

[package]
name = "light_processor"
version = "0.1.0"
edition = "2018"

[dependencies]
libc = "0.2.51"
sync = "0.1.0"
enum-primitive-derive = "0.1.2"
num-traits = "0.2.6"

[lib]
name = "NativePluginRust"
crate-type = ["dylib"]

[target.'cfg(target_os="android")'.dependencies]
jni = { version = "0.5", default-features = false }

.货物/配置

[target.x86_64-linux-android]
ar = "C:\\NDK\\x86\\bin\\x86_64-linux-android-ar"
linker = "C:\\NDK\\x86_64\\bin\\x86_64-linux-android-clang++"

[target.aarch64-linux-android]
ar = "C:\\NDK\\arm64\\bin\\aarch64-linux-android-ar"
linker = "C:\\NDK\\arm64\\bin\\aarch64-linux-android-clang++"

[target.armv7-linux-androideabi]
ar = "C:\\NDK\\arm\\bin\\arm-linux-androideabi-ar"
linker = "C:\\NDK\\arm\\bin\\arm-linux-androideabi-clang++"

[target.i686-linux-android]
ar = "C:\\NDK\\x86\\bin\\i686-linux-android-ar"
linker = "C:\\NDK\\x86\\bin\\i686-linux-android-clang++"

平台及其他

Cargo/rustc version: cargo 1.35.0-nightly (0e35bd8af 2019-03-13)
Windows 10
NDK - r19c

当我运行时cargo build --target armv7-linux-androideabi --release，我得到这个编译错误：

error: could not exec the linker

这个错误背后的问题是什么？
