Continuous Integration of C/C++ Apps for IoT Devices with Jenkins, Docker and Conan

CI for IoT

This is the repository that gathers the material for the small talk and demo called: Continuous integration for C/C++ embedded devices with Jenkins, Docker and Conan

This example is used to show how cross-building and CI can be achieved using Conan to manage C/C++ dependencies in your projects.

It contains the Wiring Pi library dependency packaged with a conanfile.py ready to be cross-compiled. The profile used for that purpose is the file win_to_rpi.

The local toolchain to cross-build from Windows to armv7hf can be found in the GNU toolchains page: raspberry-gcc6.3.0.exe

Jenkins & Docker

The blink repository provides a Jenkinsfile that can be used to configure a Jenkins Multibranch job that will build the application inside the conanio/gcc6-amrv7hf Docker container configured with the cross-building toolchain for Raspberry Pi.

Demo steps

1.- Build WiringPi cross-building for armv7hf: $ conan create wiringpi conan/stable -pr win_to_rpi

2.- Upload WiringPi package to Artifactory: $ conan upload wiringpi/2.46@conan/stable -all -r artifactory_local

3.- Make changes in the Blink app and commit them: cd blink && git add . && git commit -m "faster!"

4.- Jenkins Multibranch job will start, get the latest change from blink, cross-build the application and upload it to Artifactory.
