To build it, we have to checkout v8 source and copy missing files.
I use this github workflow file to build:

name: CI

on:
  push:
    branches: [ "main" ]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v3

    - run: cargo fetch
    # symlink `v8_src` to rusty_v8
    - run: cargo metadata | node get_v8_path.js

    # FIXME: we have to checkout v8 source, because there is missing files in rusty_v8
    #### start checkout v8 source
    - run: git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git --single-branch --depth=1
    - run: export PATH=$(pwd)/depot_tools:$PATH && echo $PATH && mkdir v8

    # https://v8.dev/docs/source-code
    - run: export PATH=$(pwd)/depot_tools:$PATH && cd v8 && gclient
    - run: export PATH=$(pwd)/depot_tools:$PATH && cd v8 && fetch v8

    # https://v8.dev/docs/cross-compile-arm
    - run: echo "target_os = ['android']" >> v8/.gclient
    - run: cat v8/.gclient

    - run: export PATH=$(pwd)/depot_tools:$PATH && cd v8 && gclient sync
    #### done checkout v8 source

    # copy missing files
    - run: cp -rn v8/v8/build/android v8_src/build || true

    # build
    - run: cd v8_src && rustup target add aarch64-linux-android
    - run: cd v8_src && V8_FROM_SOURCE=1 cargo build -vv --release --target aarch64-linux-android

我尝试编译 v0.83.2 成功了，但是我在使用时遇到了一些问题，使用 deno_core 运行例子时会报空指针错误，请问你成功运行了吗

以前的版本是可以的, 最新的版本有点问题, 还没成功.

我还以为是我编译v8出现问题了呢，我现在在尝试重新编译了🤦‍♂️

以前的版本确实是可以的我也一直在用，我之前用的就是 v0.64.0，只是最近我想升级就挑了 v0.83.2，没想到就遇到一些麻烦了

我刚测试分别运行 v8 和 deno_core 的 hello_world 例子
结果是 v8 的例子可以运行但 deno_core 的例子会崩溃，这是不是说明 问题就出在 deno_core，似乎是在 JsRuntime 初始化过程中崩溃的

个人对v8研究不是特别深入，看字面意思似乎是字符串相关问题导致的？看来只能换个版本了

最新版 deno (aarch64-linux-gnu) 使用 proot 是可以在 Android 正常运行的, 所以这确实是个奇怪的 BUG.

最新版 deno (aarch64-linux-gnu) 使用 proot 是可以在 Android 正常运行的, 所以这确实是个奇怪的 BUG.

根据堆栈信息我翻看了一下 deno_core 源码

bindings.rs

pub(crate) fn initialize_deno_core_namespace<'s>(
  scope: &mut v8::HandleScope<'s>,
  context: v8::Local<'s, v8::Context>,
  init_mode: InitMode,
) {
  let global = context.global(scope);
  let deno_str = v8_static_strings::new(scope, &v8_static_strings::DENO);

  let maybe_deno_obj_val = global.get(scope, deno_str.into());

  // If `Deno.core` is already set up, let's exit early.
  if let Some(deno_obj_val) = maybe_deno_obj_val {
    if !deno_obj_val.is_undefined() {
      return;
    }
  }
...

&v8_static_strings::DENO 似乎是这个导致的？

bindings.rs

pub mod v8_static_strings {
  pub fn new<'s>(
    scope: &mut v8::HandleScope<'s>,
    str_: &'static v8::OneByteConst,
  ) -> v8::Local<'s, v8::String> {
    v8::String::new_from_onebyte_const(scope, str_).unwrap()
  }

  pub fn new_from_static_str<'s>(
    scope: &mut v8::HandleScope<'s>,
    str_: &'static [u8],
  ) -> v8::Local<'s, v8::String> {
    v8::String::new_external_onebyte_static(scope, str_).unwrap()
  }

  macro_rules! onebyte_const {
    ($ident:ident, $str_:literal) => {
      pub static $ident: v8::OneByteConst =
        v8::String::create_external_onebyte_const($str_.as_bytes());
    };
  }

  onebyte_const!(DENO, "Deno");
  onebyte_const!(CORE, "core");
  onebyte_const!(OPS, "ops");
...

onebyte_const!(DENO, "Deno"); 会生成一个 OneByteConst

v8/string.rs

  // Creates a v8::String from a `&'static [u8]`,
  // must be Latin-1 or ASCII, not UTF-8 !
  #[inline(always)]
  pub fn new_external_onebyte_static<'s>(
    scope: &mut HandleScope<'s, ()>,
    buffer: &'static [u8],
  ) -> Option<Local<'s, String>> {
    let buffer_len = buffer.len().try_into().ok()?;
    unsafe {
      scope.cast_local(|sd| {
        v8__String__NewExternalOneByteStatic(
          sd.get_isolate_ptr(),
          buffer.as_ptr() as *const char,
          buffer_len,
        )
      })
    }
  }

然后在 v8 会使用这个 v8__String__NewExternalOneByteStatic 在往下就是 v8 的 c源码了
估计是这里引用了空指针了吧，似乎是因为没对齐导致的？(没有那么了解)

Sorry for bumbling into this thread but the timing seemed serendipitous, since I was also trying to get some Android Deno builds off the ground.

I ran exactly into the:

[v8 0.74.1] ERROR at //build/android/BUILD.gn:93:17: Could not read file.
[v8 0.74.1]   pydeps_file = "pylib/results/presentation/test_results_presentation.pydeps"
[v8 0.74.1]                 ^------------------------------------------------------------

I'm not sure if you folks already have a plan of action but wouldn't it be possible to tweak the "gn gen" incantation to exclude all the testonly targets? Presumably we don't care about test targets for rusty_v8 or Deno. Ideally, this wouldn't only solve the issue at hand but also slim builds?
