Craft a C or C++ app¶

This how-to guide covers the steps, decisions, and implementation details that are unique when crafting a snap based on C or C++. We’ll work through the aspects unique to these apps by examining an existing project.

The process of developing a snap for a C or C++ app builds on top of standard tools like Autotools and Make, making it possible to adapt or integrate an app’s existing build tooling into the crafting process.

Example project file for moon-buggy¶

The following code comprises the project file for the C app moon-buggy. This project is a small game where you drive a buggy across the moon’s surface.

moon-buggy project file

snapcraft.yaml¶

name: moon-buggy
base: core22
version: "1.0.51"
summary: Drive a car across the moon
description: |
  Moon-buggy is a simple character graphics game, where you drive some
  kind of car across the moon's surface. Unfortunately there are
  dangerous craters there. Fortunately your car can jump over them!
confinement: devmode
parts:
  moon-buggy:
    plugin: autotools
    autotools-configure-parameters: ["--prefix=/usr"]
    source: .
    build-packages:
      - libncurses-dev
      - texinfo
apps:
  moon-buggy:
    command: usr/bin/moon-buggy

Add a part written in C or C++¶

snapcraft.yaml¶

parts:
  moon-buggy:
    plugin: autotools
    autotools-configure-parameters: ["--prefix=/usr"]
    source: .
    build-packages:
      - libncurses-dev
      - texinfo

C and C++ parts are built with the autotools, make, or cmake plugins.

The project file uses the Autotools plugin, and a special autotools-configure-parameters key to override the autotools command’s --prefix argument, which would typically default to /usr/local.

To declare a part written in C or C++:

Declare the general part keys, such as source, override-build, build-packages, and so on.
Set plugin to autotools, make, or cmake.
