Supported Systems

Version 2 currently supports only GNU systems (both Hurd-based and Linux-based). The list of supported architectures is

• GNU/Hurd. We believe all platforms the Hurd runs on are also supported by GNU libc.
• GNU/Linux. GNU libc works with the Linux kernel, version 2.0.10 or later, on the following architectures:
  • Intel ix86
  • Motorola 680x0
  • DEC Alpha
  • PowerPC (32 and 64 bit)
  • Sparc
  • Sparc64
  • ARM
  • MIPS (Kernels > 2.2.15)
  • Intel IA64 (Kernels > 2.4.0)
  • IBM S/390 (32 and 64 bit)
  • SH
  • CRIS
  • AMD x86-64

Subtree Maintainers

The system-dependent parts of glibc are organised in subtrees which are used for different systems or different architectures. While the glibc maintainers are responsible for the whole system, some of the subtrees are maintained by other people as well. The following table lists the subdirectories, describes briefly the contents, and shows who can be contacted. Every directory listed includes all directories below it as well.

All architecture-specific or system-specific directories not listed here are currently not actively maintained.

Ongoing work

Other ports are being developed but are not yet usable. If you are interested in porting GNU libc, please to see whether somebody is already working on your system or a related system.

No new ports under development

If you have interest in working on one of the systems listed above, please contact the appropriate people and also drop a note to the GNU libc maintainers <libc-alpha@sources.redhat.com> so that this table can be updated.

If you have interest in working on a system not listed above, please contact the GNU libc maintainers <libc-ports@sources.redhat.com> so that duplicate work can be avoided.

Chances are that your particular port will find a home in the `ports' package, which has been available since version 2.3.4. This add-on package is the home for code supporting machines and operating systems maintained only by volunteers, not as part of the core glibc maintenance effort. Queries about the ports system should be directed to <libc-ports@sources.redhat.com>.
