This guide covers configuring continuous integration pipelines for C++ projects. If you’re new to Drone please read our Tutorial and build configuration guides first.

Build and Test

In the below example we demonstrate a pipeline that executes make and make test commands. These commands are executed inside the gcc Docker container, downloaded at runtime from DockerHub.

kind: pipeline
type: kubernetes
name: default

steps:
- name: test
  image: gcc
  commands:
  - ./configure
  - make
  - make test

Please note that you can use any Docker image in your pipeline from any Docker registry. You can use the official gcc images, or your can bring your own.

Test Multiple Architectures

You can use Drone’s multi-pipeline feature to concurrently test your code on multiple architectures and operating systems.

---
kind: pipeline
type: kubernetes
name: test-on-amd64

platform:
  arch: amd64

steps:
- name: test
  image: gcc
  commands:
  - ./configure
  - make
  - make test

---
kind: pipeline
type: kubernetes
name: test-on-arm64

platform:
  arch: arm64

steps:
- name: test
  image: gcc
  commands:
  - ./configure
  - make
  - make test

...

If you find this syntax too verbose we recommend using jsonnet. If you are unfamiliar with jsonnet please read our guide.

local Pipeline(version, arch) = {
  kind: "pipeline",
  type: "kubernetes",
  name: "test-on-"+arch,
  platform: {
    arch: arch,
  }
  steps: [
    {
      name: "test",
      image: "gcc",
      commands: [
        "./configure",
        "make",
        "make test"
      ]
    }
  ]
};

[
  Pipeline("arm"),
  Pipeline("arm64"),
  Pipeline("amd64"),
