GNU Tools Cauldron 2025

GNU C Library BoF
2025-09-26 , Auditorium B032

The GNU C Library is used as the C library in the GNU systems and many other systems with the Linux kernel. The library is primarily designed to be a portable and high performance C library. It aims to follows all relevant standards including ISO C17 and POSIX.1-2008. It is also internationalized and has one of the most complete internationalization interfaces known.


This BoF aims to bring together developers of other components that have dependencies on glibc and glibc developers to talk about the following topics:

  • Planning for glibc 2.43 and what work needs to be done
    between September 2025 and February 2026.

  • Planning for glibc 2.44 and what work needs to be done
    between February 2026 and August 2026.

  • Can we try month-to-month feature planning again?

... and more.
