eBuild — Build System & SDK Generator
eBuild is the EoS build system and SDK generator — an 18-command CLI that drives configuration, cross-compilation, signing, packaging, and SDK generation for all 14 EoS components across every supported target.
What eBuild is
eBuild treats firmware as a composition: pick a board, pick a profile, pick a feature set, and eBuild resolves the dependency graph, fetches sources at pinned revisions, cross-compiles, signs, and produces a flashable artifact plus a matching SDK for downstream apps.
Builds are reproducible by default: same inputs, byte-identical outputs. CI integration is first-class — the same `ebuild` commands run locally and in pipelines.
Features
The shape of eBuild at a glance.
18-Command CLI
init, configure, build, sign, package, sdk, test, fuzz, deploy, bench, debug, …
14 SDK Targets
Auto-generates a build SDK for every component (EoS, EAI, ENI, EIPC, eBoot, eApps, …).
Profile Composition
Combine board + product profile + feature flags; resolves the full dependency graph.
Reproducible Builds
Pinned source revs, isolated toolchains, hash-stable outputs.
Cross-Compile Matrix
ARM, AArch64, RISC-V, x86_64 toolchains managed automatically.
Signing & Packaging
Built-in Ed25519 signing, .eos / .img / .hex / .uf2 packaging.
CI-First
GitHub Actions, GitLab CI, Jenkins recipes shipped; same commands locally and in CI.
Bench & Fuzz
Integrated micro-benchmark and fuzzer drivers for kernel / app modules.
Workspace Mode
Multi-repo monorepos with shared toolchain caches.
Open source on GitHub
eBuild is Apache-2.0 licensed and developed in the open. Issues, discussions, and pull requests welcome.
