Level: Beginner+ (and curious experts)
Goal: Get your first (or your nth) patch merged into the GNU C Library!

After two years of incredible growth, jumping from six patches in 2024 to over fifteen submitted in 2025, the glibc development workshop is back for its third year. Whether you are new to C or a seasoned systems engineer, you can help us make the GNU C Library better, one patch at a time.

As in previous years, we will work on picking low-hanging fruit, producing small, incremental improvements, and getting some new names (yours?) on the glibc commit log. We will fix typos, improve documentation, improve existing tests, add new ones, and even squash a bug or three.

The workshop starts with a quick introduction to glibc and its codebase. Then, each willing participant will receive an individual cheat-sheet featuring one small, well-defined problem and pointers on how to solve it. Experienced glibc contributors will be around to help you across the finish line.
