Its stated goal is to approximate Rust Cargo's convenience for C and C++ while keeping enough depth for complex real-world build requirements. The toolchain is intentionally hierarchical: `b` is the general-purpose build system, `bpkg` handles package consumption, and `bdep` handles project development. The `build2-toolchain` repository is an amalgamation used to build and package those components together. ### 采用历史 build2 has remained a specialist C/C++ toolchain rather than a default ecosystem standard like CMake, but its own community page says it is used for real development and cites customer-facing software such as ODB and XSD. The project also maintains cppget.org as its package repository. It is packaged by Homebrew, Nix, Fedora-style `bdep` packages, and Windows winget according to the input. Upstream development happens in self-hosted git repositories on git.build2.org with GitHub mirrors for collaboration. ### 使用方式 Users typically create or initialize projects with `bdep`, build with `b`, and consume dependencies with `bpkg`. The documented configuration surface includes project-local `build/config.build`, `.build2/` state, `.build2/local/`, user-level `~/.build2/`, and system-level `/etc/build2/` locations. The toolchain is aimed primarily at C/C++ and mixed-language projects involving C or C++, though the project describes a longer-term universal build-toolchain goal. ### 为什么软件包爱好者会关心 build2 is significant because it is one of the more complete attempts to give C and C++ a Cargo-like combined build, package, and project-management workflow without hiding the complexity needed by native-code builds. For package managers, it is also recursive in an interesting way: the build2 toolchain is used for its own development, and the upstream amalgamation repository exists specifically to make source builds and binary packaging of the whole toolchain practical. ### 时间线 - 2014: build2 documentation copyright begins, marking the early public project era. - 2010s: Public 0.x toolchain tags began with 0.1.0 and evolved through the pre-1.0 series. - 2018: The project pointed users to a CppCon 2018 presentation as a toolchain overview. - 2020s: The community page described build2 as in the final stage of pre-1.0 development and already used in projects such as ODB and XSD. - 2026: The Toolchain Introduction metadata showed version 0.18 and copyright through 2026. ### Related projects - Cargo is the explicit convenience benchmark named by the build2 homepage. - CMake and Autotools are common neighboring C/C++ build-system incumbents, though build2 packages build, dependency, and project management together. - cppget.org is the build2 package repository referenced by the project community page. ### 来源 - - - - - source_facts.package-manager ## 安全说明 generalized runtime or code generation signal. - **Geiger 风险:** yellow / 中 - generalized runtime or code generation signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
