Generating and Managing C and C++ SBOMs
A FOSSA blog post explaining why C/C++ SBOMs built from manifest-parsing alone are incomplete, since the ecosystem lacks a centralized package manager and relies heavily on vendored (copy-pasted) source and code snippets. It covers concrete generation paths: Conan's built-in conan.tools.sbom CycloneDX generator, Yocto/OpenEmbedded's native SPDX output via the create-spdx class, process-based tracking for vendored code (third_party/vendor path flagging, manual audits), and the differing snippet-support capabilities of SPDX versus CycloneDX.
