Describe the bug

Ok, this is the well-known bug that has been reported many times already. I got it in the past and got rid of it by following people's recommendations in Discussions or Issues. This time I'm stuck with this bug for over a couple of weeks and until now it was fine because I'll just run just test-pure-web instead or peek at the CI worklows execution (which just works fine, contrary to my machine lol). But this time I'm testing something and I would really like to be able to run just test-pure locally and track my progress here.

I've already tried a bunch of stuff before opening this Issue, also fixed paths around (now that we switched to cargo workspace, the target folder is systematically in root folder, not in each crate's folder).

I had to shorten the logs output because it was exceeding Github limit.

what is the full output log about that "failed to lookup symbol", i.e. output of execution

I got the path messed up in my previous output, so I fixed it (dylibPath=../../../target/debug/libflutter_rust_bridge_example.dylib)

So I added a safety net to make sure in main.dart e.g. :

if (!File(dylibPath).existsSync()) {
    throw Exception('$dylibPath does not exist');
  }

But the error persists ! 😅

Use some tools to see what is inside that dylib file.

For a linux .so file, we have nm and objdump etc. For macos IIRC there are similar things.

Then, we can know whether the symbol is really in the dylib, and if yes, what is the signature of that symbol.

I noticed that the dummy codegen doesn't appear in the bridge_generated.* files, is this important ? It seems related :

pub const DUMMY_WIRE_CODE_FOR_BINDGEN: &str = r#"
    // ----------- DUMMY CODE FOR BINDGEN ----------

    // copied from: allo-isolate
    pub type DartPort = i64;
    pub type DartPostCObjectFnType = unsafe extern "C" fn(port_id: DartPort, message: *mut std::ffi::c_void) -> bool;
    #[no_mangle] pub unsafe extern "C" fn store_dart_post_cobject(ptr: DartPostCObjectFnType) { panic!("dummy code") }

    // copied from: frb_rust::support.rs
    #[repr(C)]
    pub struct WireSyncReturnStruct {
        pub ptr: *mut u8,
        pub len: i32,
        pub success: bool,
    }

    // ---------------------------------------------
    "#;

fzyzcjy · 2022-09-30T11:54:03Z

IIRC that is created and then removed later? forget the details

Roms1383 · 2022-09-30T11:58:08Z

I'm sorry I actually don't know what is IIRC (answers on Google seemed unrelated, even with keywords). People recommended otool on macos but ... I don't even know what I'm supposed to look for ^^'

Ah wait, here you go I guess nm -gU target/debug/libflutter_rust_bridge_example.dylib.

Apparently the symbol is present : 0000000000128b5c T _store_dart_post_cobject

fzyzcjy · 2022-09-30T12:09:20Z

;)

fzyzcjy · 2022-09-30T12:10:21Z

the weird thing is:

  void store_dart_post_cobject(
    DartPostCObjectFnType ptr,
  ) {
    return _store_dart_post_cobject(
      ptr,
    );
  }

  late final _store_dart_post_cobjectPtr =
      _lookup<ffi.NativeFunction<ffi.Void Function(DartPostCObjectFnType)>>('store_dart_post_cobject');
  late final _store_dart_post_cobject = _store_dart_post_cobjectPtr.asFunction<void Function(DartPostCObjectFnType)>();

typedef DartPostCObjectFnType = ffi.Pointer<ffi.NativeFunction<ffi.Bool Function(DartPort, ffi.Pointer<ffi.Void>)>>;
typedef DartPort = ffi.Int64;

that type looks correct to me

fzyzcjy · 2022-09-30T12:12:01Z

so maybe do some reduction?

for example, write some dart code:

is the symbol storedartpostcobject provided? https://api.dart.dev/stable/2.18.2/dart-ffi/DynamicLibrary/providesSymbol.html
can we lookup another symbol, e.g. _wire_handle_sync_i8?
can we lookup symbols in other dylib files?

Roms1383 · 2022-09-30T12:21:15Z

Found it :

If I replace :

DynamicLibrary.executable() with DynamicLibrary.open(path) (like in non-IOS/MacOS) in frb_example/pure_dart/dart/lib/ffi.io.dart it works.

FlutterRustBridgeExampleSingleBlockTestImpl initializeExternalLibrary(String path) {
  return FlutterRustBridgeExampleSingleBlockTestImpl(
    Platform.isMacOS || Platform.isIOS ? DynamicLibrary.executable() : DynamicLibrary.open(path),
  );
}

I have no idea why though.

Roms1383 · 2022-09-30T12:23:13Z

Is this MacOS ARM specific ? or is DynamicLibrary.executable() wrong for all iOS/MacOS ?

fzyzcjy · 2022-09-30T12:29:13Z

weird... the lib works well for me, in macos intel

Roms1383 · 2022-09-30T12:43:23Z

Should we add another check based on Platform.operatingSystemVersion to differentiate between MacOS Intel and MacOS ARM ? I checked already there's no mention of M1 in e.g. Platform.isIOS and the other methods.

Roms1383 · 2022-09-30T12:44:42Z

Here's what I get on my machine : Version 12.4 (Build 21F79)

fzyzcjy · 2022-09-30T12:48:43Z

really not sure what is happening here. maybe not a problem between m1 and intel, but problem elsewhere in the toolchain config?

maybe add this to doc, telling people to try changing what you have changed.

and also add a link from doc to here. if many people see same problem we will know whether it is M1 or sth else causes it

Roms1383 · 2022-09-30T12:53:00Z

I might be a bit slow, but I'll try to do it asap 👌

Roms1383 · 2022-10-02T04:33:19Z

I'm gonna include a quick fix in the coming PR #755 to remediate :
By changing ffi.io.dart files from:

e.g. flutter_rust_bridge/frb_example/pure_dart/dart/lib/ffi.io.dart

// ...
FlutterRustBridgeExampleSingleBlockTestImpl initializeExternalLibrary(String path) {
  return FlutterRustBridgeExampleSingleBlockTestImpl(
    Platform.isMacOS || Platform.isIOS ? DynamicLibrary.executable() : DynamicLibrary.open(path),
  );
}

To:

// ...
FlutterRustBridgeExampleSingleBlockTestImpl initializeExternalLibrary(String path) {
  return FlutterRustBridgeExampleSingleBlockTestImpl(
    (Platform.isMacOS || Platform.isIOS) &&
              !const bool.fromEnvironment('SILICON', defaultValue: false)
          ? DynamicLibrary.executable()
          : DynamicLibrary.open(path),
  );
}

And updating related just commands to accept extra CLI arg(s) + pipe it to Dart run command, one can just append --define=SILICON=true to his/her commands to workaround this issue until Dart provide a way to clearly differentiate a MacOS Silicon from an older generation MacOS and be handled automatically by FRB.

fzyzcjy · 2022-10-02T05:08:32Z

@Roms1383 LGTM, just a few small points

could you please make it a separate PR, so it is easier to manage :)
maybe change it to DYNAMIC_LIBRARY_SOURCE which is an enum (string)

Roms1383 · 2022-10-02T05:43:29Z

could you please make it a separate PR, so it is easier to manage :)

That's a bit tedious, but can if you want.

maybe change it to DYNAMIC_LIBRARY_SOURCE which is an enum (string)

Hmmm why DYNAMIC_LIBRARY_SOURCE ? SILICON seems more explicit, doesn't it ?

fzyzcjy · 2022-10-02T05:46:17Z

That's a bit tedious, but can if you want.

According to flutter repo suggestion, even one PR for one very tiny change :)

Hmmm why DYNAMIC_LIBRARY_SOURCE ? SILICON seems more explicit, doesn't it ?

Usage: --define DYNAMIC_LIBRARY_SOURCE=executable, --define DYNAMIC_LIBRARY_SOURCE=path, etc

Roms1383 · 2022-10-02T06:38:43Z

@fzyzcjy am I allowed to upgrade Dart SDK minimum requirement from 2.14.0 to 2.17.0 ? That would allow using enhanced-enums feature from Dart, and be able to write cool stuff like e.g. :

enum DylibSourceKind {
    process,
    executable,
    open;
    static DylibSourceKind? fromEnvironment(String arg) {
      // ...
   }
}

fzyzcjy · 2022-10-02T06:41:14Z

I think so, especially we have made min rust be 1.64.0.

Desdaemon · 2022-10-06T04:49:56Z

Don't have an Intel Mac to test this, but I suspect DynamicLibrary.executable for pure_dart MacOS might be bugged code. That method points to the dart executable as the dylib source, so understandably it won't have our symbols. If this is true, it wouldn't really matter if it was on Apple Silicon or not. Also I don't think we're running unit tests on iOS so the entire conditional dylib loading can be omitted.

fzyzcjy · 2022-10-10T01:12:34Z

Interestingly, as reported in #772 (comment), seems another M1 person sees this problem

kingfisherphuoc · 2022-10-12T08:36:34Z

I had the same issue on a Flutter project. It's solved by this:

final Native api = NativeImpl(
    ((io.Platform.isIOS || io.Platform.isMacOS) && !const bool.fromEnvironment('SILICON', defaultValue: false))
        ? DynamicLibrary.executable()
        : DynamicLibrary.open(_dylib));

justinmoon · 2022-10-18T13:13:22Z

I ran into this problem trying to write a dart test of my rust code on an m1 mac.

Here I forked the template and added one tiny unittest. When I run flutter test test/bridge_test.dart I get the Failed to lookup symbol 'store_dart_post_cobject': dlsym(RTLD_DEFAULT, store_dart_post_cobject): symbol not found error.

The SILICON environment variable mentioned above doesn't work and gives this error:

  Invalid argument(s): Failed to load dynamic library 'libbridge.so': dlopen(libbridge.so, 0x0001): tried: '/Users/justin/bin/flutter/bin/cache/artifacts/engine/darwin-x64/./libbridge.so' (no such file), '/Users/justin/bin/flutter/bin/cache/artifacts/engine/darwin-x64/../../../libbridge.so' (no such file), '/Users/justin/bin/flutter/bin/cache/artifacts/engine/darwin-x64/Frameworks/libbridge.so' (no such file), '/Users/justin/bin/flutter/bin/cache/artifacts/engine/darwin-x64/./libbridge.so' (no such file), '/Users/justin/bin/flutter/bin/cache/artifacts/engine/darwin-x64/../../../libbridge.so' (no such file), '/Users/justin/bin/flutter/bin/cache/artifacts/engine/darwin-x64/Frameworks/libbridge.so' (no such file), 'libbridge.so' (no such file), '/usr/lib/libbridge.so' (no such file), '/Users/justin/fedimint/mobile2/apps/fedi/libbridge.so' (no such file)

fzyzcjy · 2022-10-18T13:14:45Z

The SILICON environment variable

Could you please check whether it is in master branch. If not, you need to modify code as suggested.

Roms1383 · 2022-10-18T13:16:31Z

@fzyzcjy @justinmoon the SILICON workaround hasn't been merged yet, please add it manually for now.

fzyzcjy · 2022-10-18T13:17:17Z

@Roms1383 Btw for your SILICON pr - given all these reports, I now totally agree it is named "silicon" and just do it the simple way.

justinmoon · 2022-10-18T13:38:11Z

If I just do the following in the template, it still doesn't work with the Failed to load dynamic library 'libbridge.so' error. So I'm not sure the SILICON workaround will work for me, because this is what it attempts to do right?

final Native api = NativeImpl(DynamicLibrary.open(_dylib));
