`flutter_rust_bridge_codegen` panics: `system cannot find the file specified.` when executing `dart` command using Rust's `Command` #81

emperor-limitless · 2021-10-15T13:03:28Z

When trying to generate using flutter_rust_bridge, The bridge_generated.rs file gets created, However, It scene to crash after doing that with a not foudn file panic.

I ran the command like this
flutter_rust_bridge_codegen --rust-input src/api.rs --dart-output fastengine.dart --c-output fastengine.h

The error is this

Hi! Thanks for opening your first issue here! 😄

fzyzcjy · 2021-10-15T13:05:04Z

let me have a look

fzyzcjy · 2021-10-15T13:07:00Z

please Run code generator with RUST_LOG environment variable set to debug, and paste them here.
please checkout code at a stable tag, e.g. https://github.com/fzyzcjy/flutter_rust_bridge/tree/v1.1.0 , instead of directly use master which can be unstable (though CI passes)
If possible, please paste your generated binding code, both .h (via --c-output), and .dart (via --dart-output), here.
please fill in following info

OS: [e.g. MacOS]
Version [e.g. 11]
Version of flutter_rust_bridge_codegen: [e.g. 1.0]
Paste output of flutter doctor -v: [paste below]
Version of clang++: [e.g. 12]
Version of cbindgen: [e.g. 0.20]
Version of ffigen: [e.g. 0.4]

let me have a look

fzyzcjy · 2021-10-15T22:55:15Z

Sounds like you do not have dart when executing shell commands using Rust's Command? Can you run, say, dart pub global run ffigen in shell? Moreover, could you please compile and run the following program to see whether it runs on your machine or not (paste the output)?

use std::fs;
use std::io::Write;
use std::process::Command;

fn main() {
    execute_command(
        Command::new("dart")
            .arg("pub")
            .arg("global")
            .arg("run")
            .arg("ffigen");
    );
}

fn execute_command(command: &mut Command) {
    println!("execute command: {:?}", command);

    let result = command.output().unwrap();

    if result.status.success() {
        println!("command={:?} output={:?}", command, result);
    } else if String::from_utf8_lossy(&result.stdout).contains("fatal error") {
        println!(
            "See keywords such as `error` in command output. Maybe there is a problem? command={:?} output={:?}",
            command, result
        );
        // only warn, do not panic
    } else {
        println!("command={:?} output={:?}", command, result);
        panic!("command execution failed. command={:?}", command);
    }
}

I am using Rust's Command to execute commands - that should be quite standard

emperor-limitless · 2021-10-16T05:16:59Z

Yes, I did the steps on the main github page, And running dart pub global run ffigen gives

Running in Directory: 'C:\Users\mohamed\projects\lom'
[SEVERE] : Couldn't find an entry for 'ffigen' in pubspec.yaml.

Tried the rust code, And

execute command: "dart" "pub" "global" "run" "ffigen"
thread 'main' panicked at 'called Result::unwrap() on an Err value: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }', rusttest.rs:18:35
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

fzyzcjy · 2021-10-16T05:35:48Z

Aha, so that is problem of Rust's builtin Command.

Running in Directory: 'C:\Users\mohamed\projects\lom'
[SEVERE] : Couldn't find an entry for 'ffigen' in pubspec.yaml.

This means the dart command can be found (ignore the "SEVERE" since we really do not give it a yaml).

thread 'main' panicked at 'called Result::unwrap() on an Err value: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }', rusttest.rs:18:35

This means Rust's builtin Command fails to work.

It seems to be the setup problem of your computer.

emperor-limitless · 2021-10-16T06:16:21Z

So what should I do? Reinstall rust?

fzyzcjy · 2021-10-16T06:18:38Z

No. I guess it is problem of environment variables. Search for things like, e.g., Rust's Command says `The system cannot find the file specified.

fzyzcjy · 2021-10-16T06:20:06Z

I do not have a windows computer at my hand. You may also look at the CI: https://github.com/fzyzcjy/flutter_rust_bridge/blob/master/.github/workflows/codegen.yml it runs code generator on windows (as well as mac and linux) and it works

High-level memory-safe binding generator for Flutter/Dart <-> Rust - flutter_rust_bridge/codegen.yml at master · fzyzcjy/flutter_rust_bridge

fzyzcjy · 2021-10-16T06:21:19Z

I suspect how you install dart command. Maybe you need to consider PATH environment variable as well.

emperor-limitless · 2021-10-16T08:20:32Z

Alright, I see now, It seems since I was using the dart installation used with flutter, It was erroring for some reason, So I replaced the flutter dart with the dart from the official site and it works, Thanks for the help.

fzyzcjy · 2021-10-16T10:29:03Z

You are welcome! Glad you find out the solution.
