[SOLVED] How to build a dart server in a single file and run it on the Ubuntu server? (`dart compile exe` give an error)

Issue

My host is Ubuntu 20.04(x86_64) and my PC is Windows 10 Home (64-bit operating system, x64-based processor). I want to build a dart server to a single file. So, I used this command

dart compile exe dart_server/bin/dart_server.dart -o dart_server-linux-x64

to build the dart_server-linux-x64 file and move it to the host. and run this file by

./dart_server-linux-x64

Then I got the error:

-bash: ./dart_server-linux-x64: cannot execute binary file: Exec format error

How to solve that? I tried uploading the folder project(dart_server). Then run this dart server from this folder and it works successfully. But I want to use a single file, not the whole folder project. How to fix that?

Solution

Answer here.

We can build dart project into .exe file by using git action.

I have the dart_server and dart_share(using in flutter and dart_server projects) projects.

This is my the directory structure

root
     - .github
          - workflows
               - github-actions-demo.yml
               
     - dart_server
          - bin
               - dart_server.dart
          - pubspec.yaml

     - dart_share
          - pubspec.yaml

The github-actions-demo.yml is

# This is a basic workflow to help you get started with Actions

name: CI Building native server

# Controls when the workflow will run
on:
  # Triggers the workflow on push or pull request events but only for the main branch
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

jobs:
  build:
    runs-on: ${{ matrix.os }}

    strategy:
      matrix:
        os: [ubuntu-latest, windows-latest, macOS-latest]
        include:
          - os: ubuntu-latest
            output-name: server-linux
          - os: macOS-latest
            output-name: server-mac
          - os: windows-latest
            output-name: server-windows.exe
    steps:
      - uses: actions/checkout@v2
      - uses: dart-lang/[email protected]
      - name: Install dependencies for share project
        working-directory: ./share_dart
        run: dart pub get
      - name: Install dependencies for server project
        working-directory: ./server
        run: dart pub get
      - run: mkdir build
      - name: Install Dependencies for share project
        working-directory: ./share_dart
        run: dart pub get
      - name: Install Dependencies for server project
        working-directory: ./server
        run: dart pub get
      - run: dart compile exe ./server/bin/server.dart -v -o build/${{ matrix.output-name }}
      - uses: actions/upload-artifact@v1
        with:
          name: native-executables
          path: build
