A basic C++ exercise which uses conan to satisfy dependencies before building a shared library and an executable that links it. Also produces a .deb package which installs the executable, library, and public headers.

Prerequisites

• Ubuntu 22.04 (or equivalent)
• Additional required packages:
  • g++
  • cmake
  • python3-venv

Setup

Create a python virtual environment, install conan, and create a default profile:

python3 -m venv conan.venv
source conan.venv/bin/activate
pip install conan
conan profile detect

Building and running

1. To build, run:

   ./build.sh
   

2. The build command will generate a deb package in the _packages directory. To install (to /usr/local) run:

   sudo dpkg -i _packages/_packages/cppchallenge_1.0.0_*.deb
   sudo ldconfig
   

   TODO: The sudo ldconfig step should be added to the deb package postinst step...
3. To run:

   $ cppchallenge
   Hello World!
   File name is: aname
   $ cppchallenge --help
   Just a simple 'hello'
   Usage: cppchallenge [OPTIONS]
   
   Options:
     -h,--help                   Print this help message and exit
