Compile and test a C application

Using Codefresh pipelines

Codefresh can work with any C/C++ application very easily as both gcc and g++ are already offered in Dockerhub. There is also another example available with C++ and cmake.

The example C project

You can see the example project at https://github.com/codefresh-contrib/c-sample-app. The repository contains a C starter project with a Makefile and several targets:

• make compiles the code.
• make test runs unit tests
• make clean removes artifacts and binaries.

There are also extra targets for tags and etags.

Create a CI pipeline for C applications

Creating a CI/CD pipeline for C is very easy, because Codefresh can run any gcc image that you wish. Gcc docker images already contain the make utility.

Here is the full pipeline that compiles the application after checking out the code.

codefresh.yml

version: '1.0'
stages:
  - checkout
  - build
steps:
  main_clone:
    title: Cloning main repository...
    stage: checkout
    type: git-clone
    repo: 'codefresh-contrib/c-sample-app'
    revision: master
    git: github
  compile_my_sources:
    title: Compile
    stage: build
    image: gcc
    commands:
      - make
  run_my_tests:
    title: Test
    stage: build
    image: gcc
    commands:
      - make test   

This pipeline clones the source code, compiles the code and runs unit tests. In all cases we use the public Docker image of Gcc that also contains make.
