2. rustc 已经更新到 5-18 最新版本

3. cargo build --target aarch64-linux-android

后编译报错为

Compiling rust_android v0.1.0 (/home/XXX/Documents/Code/rust_android) error: linking with /home/dji/Android/Sdk/ndk/23.0.7599858/arm64/bin/aarch64-linux-android-gcc failed: exit status: 1 | = note: "

= note: ld: error: unable to find library -lgcc clang120: error: linker command failed with exit code 1 (use -v to see invocation)

error: could not compile rust_android due to previous error
