NINJA
A fast, minimal build system for C/C++ projects
Apache-2.0
ABOUT
Traditional build systems like Make become slow and fragile on large C/C++ codebases — incremental builds crawl, dependency tracking is error-prone, and parallel builds require manual targets. Ninja optimizes for incremental build speed by doing the absolute minimum work: it reads Ninja files (generated by CMake, Meson, or GN), resolves a DAG of build edges, and runs only the commands whose inputs changed. The result is sub-second incremental builds on projects with thousands of source files.
INSTALL
pip install ninjaINTEGRATION GUIDE
1. Replace Make as the backend build system for large C/C++ projects where every-second incremental rebuilds matter
2. Power CMake-generated builds that use Ninja as the native build tool for faster compilation on CI and developer machines
3. Build Chromium and other massive codebases that rely on Ninja's DAG scheduling for maximum parallelism
4. Serve as the build backend for Meson projects, enabling cross-platform builds with minimal overhead
5. Drive GPU kernel compilation in AI/ML frameworks like PyTorch and TensorFlow during custom op builds
