Conan (package manager) is a decentralized, open-source package manager for C and C++ designed to provide reproducible dependency management, binary package distribution, and build interoperability across platforms and build systems. It targets developers and organizations working with GNU Compiler Collection, Microsoft Visual Studio, Clang (compiler), LLVM, and continuous integration systems such as Jenkins, GitLab CI/CD, and GitHub Actions. The project emphasizes portability, transparency, and compatibility with existing tools like CMake, Meson, Autotools, and Make (software).

Overview

Conan was created to address challenges in managing native dependencies across diverse environments including Windows, Linux, macOS, and embedded platforms supported by vendors such as ARM Limited and Intel. It integrates with package hosting services and artifact repositories such as JFrog Artifactory, Bintray, and generic HTTP servers, while interoperating with source control systems like Git, Subversion, and Mercurial. Conan's model separates package recipes from binaries to support multiple Continuous integration pipelines and binary reuse across teams using tools like Travis CI, CircleCI, and Azure Pipelines.

History and Development

Conan was initially developed by company founders who later worked with JFrog and launched the project in 2016 as an alternative to language-specific managers and platform-specific package systems like vcpkg, NuGet, Homebrew, APT (Debian), and YUM. Early contributions came from engineers experienced with Mozilla, Intel, and Nokia, reflecting needs from large-scale projects such as Firefox, Chromium, and OpenStack. Over time, Conan evolved through community contributions coordinated on platforms like GitHub and discussions in forums associated with Stack Overflow and the Linux Foundation. Major milestones include support for modern build tools, native package caching to accelerate builds used by teams at Google, Facebook, and Amazon Web Services.

Features and Architecture

Conan implements a recipe-driven approach where packages are defined by Python-based recipes compatible with automation frameworks used by corporations like Red Hat and Canonical. It supports binary package creation for multiple ABIs and toolchains including MinGW, Clang, and Microsoft Visual C++, and produces artifacts consumable by build generators such as CMake and integrations with build systems including SCons and Bazel. Conan’s architecture uses local caches, remote repositories, and a resolver that handles transitive dependencies with policies influenced by package managers like Maven and npm (software). Security and provenance features align with standards advocated by organizations like Open Web Application Security Project and Linux Foundation projects for software supply chain integrity.

Usage and Commands

Users write conanfile.py recipes and interact with the tool via commands inspired by traditional CLI tools such as RPM (file format), dpkg, and pip (software). Common commands include create, install, upload, search, and remove, facilitating workflows similar to those used in GitHub Actions pipelines and Jenkins jobs. Conan integrates with IDEs and environments like Visual Studio Code, CLion (IDE), Eclipse, and Visual Studio through plugins and extensions that bridge developer workflows familiar from projects like Qt (software), Boost (C++) libraries, and OpenSSL. Advanced usage covers cross-building scenarios for targets supported by ARM Cortex-M and containerized builds using Docker and Kubernetes orchestration used by Google Kubernetes Engine.

Ecosystem and Integrations

The Conan ecosystem includes community and commercial repositories, tooling integrations, and third-party extensions maintained by organizations such as JFrog, Conan Community, and users from Microsoft Corporation, Intel Corporation, and NVIDIA. It interoperates with package registries and CI/CD platforms like Azure DevOps, Bitbucket, and Artifactory while supporting binary caching strategies familiar to teams at Spotify and Netflix. The ecosystem hosts recipes for prominent libraries including Boost (C++) libraries, OpenCV, Poco (C++ Libraries), Google Test, and ZeroMQ, enabling reuse across projects like ROS (Robot Operating System), TensorFlow, and OpenCV-based applications. Community governance and contributions are coordinated through channels used by projects such as Apache Software Foundation initiatives and developer communities on Reddit and Stack Overflow.

Reception and Adoption

Conan has been adopted by enterprises, open-source projects, and research organizations seeking robust native dependency management, earning mentions in industry analyses alongside vcpkg, Meson, and Bazel. Analysts from firms that study Gartner (company) and practitioners from IEEE conferences have discussed Conan in the context of software supply chain management and reproducible builds for projects like LibreOffice and Qt (software). Adoption is notable in sectors represented by Automotive Grade Linux, Aerospace, and research labs at institutions such as MIT, Stanford University, and ETH Zurich, where cross-platform C++ builds are essential.
