uClibc - a small libc implementation
Erik Andersen <erik@codepoet.org>
uClibc (aka µClibc/pronounced yew-see-lib-see) is size-optimized
implementation of the standard C library. The primary use is
for developing embedded Linux systems. It is much smaller then
the GNU C Library (glibc), but nearly all applications supported
by glibc also compile and work perfectly with uClibc. Porting
applications from glibc to uClibc typically involves just
recompiling the source code. uClibc even supports shared
libraries and threading. It currently runs on standard Linux
and MMU-less Linux (also known as µClinux) systems on the
following processors: ARM, i386, h8300, m68k, mips, mipsel,
PowerPC, SH, SPARC, and v850.
For installation instructions, see the file INSTALL.
This distribution contains a wrapper for gcc and ld that allows
you to use existing toolchains that were targetted for glibc.
See extra/gcc-uClibc/ for information.
uClibc strives to be standards compliant, which means that most
documentation written for functions in glibc also apply to uClibc
functions. However, many GNU extensions are not supported
because they have not been ported, or more importantly, would
increase the size of uClibc disproportional to the added
functionality.
Additional information (recent releases, FAQ, mailing list, bugs,
etc.) can be found at http://www.uclibc.org/.
uClibc may be freely modified distributed under the terms of the
GNU Library General Public License, which can be found in the
file COPYING.LIB.
