Deno

基础rust项目命令

直接执行 main.rs

cargo run

编译出 android lib

rustup  target add aarch64-linux-android

cargo build --target=aarch64-linux-android --release

cargo build --target=aarch64-apple-darwin --release

修改默认编译器

rustup set default-host x86_64-pc-windows-msvc
rustup set default-host x86_64-pc-windows-gnu

如果遇到v8报错需要设置环境变量

$env:RUSTY_V8_MIRROR="D:/dev\AndroidStudioProjects\RustEample\rust_lib\assets\rusty_v8_mirror\"
$env:RUSTY_V8_ARCHIVE="D:\dev\AndroidStudioProjects\RustEample\rust_lib\assets\rusty_v8_mirror\v0.42.0\rusty_v8_release_x86_64-pc-windows-msvc.lib"
$env:RUSTY_V8_ARCHIVE="D:\dev\AndroidStudioProjects\RustEample\rust_lib\assets\rusty_v8_mirror\v0.42.0\librusty_v8_release_aarch64-linux-android.a"
set RUSTY_V8_MIRROR=D:\dev\AndroidStudioProjects\RustEample\rust_lib\assets\rusty_v8_mirror\
set RUSTY_V8_ARCHIVE=D:\dev\AndroidStudioProjects\RustEample\rust_lib\assets\rusty_v8_mirror\v0.42.0\rusty_v8_release_x86_64-pc-windows-msvc.lib
export RUSTY_V8_MIRROR="/mnt/d/dev/AndroidStudioProjects/RustEample/rust_lib/assets/rusty_v8_mirror/"

修复unable to find library -lgcc的问题

网上有一种错误说法，其实只能让编译通过，实际是运行的时候会爆出错误：

cd /Users/kzf/Library/Android/sdk/ndk/24.0.8215888/toolchains/llvm/prebuilt/darwin-x86_64/lib64/clang/14.0.1/lib/linux/aarch64
echo "INPUT(-lunwind)" > libgcc.a

java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "__emutls_get_address" referenced by "/data/app/~~xgQux0SWdH8NR7GLHyXCNg==/org.bfchain.rust.example-1rL1uIoeTHAxKOyHiDM32w==/base.apk!/lib/arm64-v8a/librust_lib.so"...

目前已知的解决方法就是把ndk锁在22版本以下

修复 failed to run custom build command for ring v0.16.20

运行

RUST_BACKTRACE=1 cargo build --target=aarch64-linux-android --release

发现

 --- stderr

  error occurred: Failed to find tool. Is `aarch64-linux-android-clang` installed?

原因是环境变量的名称错误，需要更改一下

cd /Users/mac/Library/Android/sdk/ndk/21.3.6528147/toolchains/llvm/prebuilt/darwin-x86_64/bin/

cp aarch64-linux-android28-clang aarch64-linux-android-clang

修复error: failed to run custom build command for libffi-sys v1.3.2

brew install autoconf automake libtool

然后 在ext/ffi/cargo.toml 修改版本为：libffi = "3.0.0"
