Supported Configurations

The GNU C Library currently supports configurations that match the following patterns:

alpha-*-linux
arm-*-linux
arm-*-linuxaout
arm-*-none
ix86-*-gnu
ix86-*-linux
m68k-*-linux
powerpc-*-linux
sparc-*-linux
sparc64-*-linux

Former releases of this library (version 1.09.1 and perhaps earlier versions) used to run on the following configurations:

alpha-dec-osf1
alpha-*-linuxecoff
ix86-*-bsd4.3
ix86-*-isc2.2
ix86-*-isc3.n
ix86-*-sco3.2
ix86-*-sco3.2v4
ix86-*-sysv
ix86-*-sysv4
ix86-force_cpu386-none
ix86-sequent-bsd
i960-nindy960-none
m68k-hp-bsd4.3
m68k-mvme135-none
m68k-mvme136-none
m68k-sony-newsos3
m68k-sony-newsos4
m68k-sun-sunos4.n
mips-dec-ultrix4.n
mips-sgi-irix4.n
sparc-sun-solaris2.n
sparc-sun-sunos4.n

Since no one has volunteered to test and fix these configurations, they are not supported at the moment. They probably don't compile; they definitely don't work anymore. Porting the library is not hard. If you are interested in doing a port, please contact the glibc maintainers by sending electronic mail to bug-glibc@gnu.org.

Each case of `ix86' can be `i386', `i486', `i586', or `i686'. All of those configurations produce a library that can run on any of these processors. The library will be optimized for the specified processor, but will not use instructions not available on all of them. If you want the library to use instructions only available on newer processors, give GCC the appropriate `-m' switches via CFLAGS.
