Aya Cross-Dev-Env for aarch64

- ebpf aya

Anything

最近想试试 Ebpf ，于是想着 Rust 的工具链会相对好用也比较齐全，实际上并没有想象的那么轻松。尤其是在 Mac 上编译，困难重重。

主要的问题一个是 Macos 本身并不支持 Ebpf 所以他没有那些 Ebpf 的 libc 头文件，在 crate::libc 中，就会缺少定义，代码提示就会出问题，链接也会出问题。安装官方文档配置了相应的环境，还是编译不过。索性放弃了，选择装了个虚拟机来编译，就没什么问题了。

For Ubuntu x86_64

  1. Install Rust
    rustup install stable
rustup toolchain install nightly --component rust-src
cargo install bpf-linker
cargo install cargo-generate
    IF DOWNLOAD VERY SLOW TRY:
    export RUSTUP_DIST_SERVER="https://rsproxy.cn"
export RUSTUP_UPDATE_ROOT="https://rsproxy.cn/rustup"
  2. Install musl-tools
    curl -s musl.cc | grep aarch64
wget https://musl.cc/aarch64-linux-musl-cross.tgz
tar -zxvf aarch64-linux-musl-cross.tgz
# ADD IT TO YOUR PATH
# eg.
export PATH=${PATH}:/repalce/with/your/unzip_path/aarch64-linux-musl-cross/bin
  3. Build Test
    cargo generate --name myapp -d program_type=xdp https://github.com/aya-rs/aya-template
cd myapp
export ARCH=aarch64
cargo build --package myapp --release --target=${ARCH}-unknown-linux-musl
--config=target.${ARCH}-unknown-linux-musl.linker=\"${ARCH}-linux-musl-gcc\"
  4. If you want to make “–config” global
     printf "[target.aarch64-unknown-linux-musl]\n" >> ~/.cargo/config.toml
 printf 'linker = "aarch64-linux-musl-gcc"\n' >> ~/.cargo/config.toml

For Macos M chip

  1. Try Official Steps refer: https://aya-rs.dev/book/start/development/

If things went wrong and YOU CAN NOT FIGURE IT OUT:

  1. Install a ubuntu vm \ ubuntu docker image

    refer: https://canonical.com/multipass/install

    refer: https://hub.docker.com/_/ubuntu

  2. Repeat Steps Mentioned Before

    YOU WILL BE FINE
