GDBS is a modern, high-performance build system for C++ projects, designed to handle thousands of source files automatically. Unlike Make, it comes with:

Automatic dependency tracking with cache-aware incremental builds

Multi-threaded compilation out of the box

A human-friendly DSL (H699) that’s easy to read, write, and extend

Automatic file expansion & combination, reducing repetitive boilerplate

Pre/post build hooks and runtime manipulators for advanced workflows

It’s written entirely in C++ using only STL, so it’s fast, portable, and lightweight. GDBS is particularly useful for large projects where traditional Makefiles become hard to manage or slow.
