It is much smaller than the GNU C Library, but nearly all applications supported +by glibc also work perfectly with uClibc.

It currently runs on standard Linux and MMU-less (also known as uClinux) +systems with support for alpha, ARM, cris, i386, i960, h8300, m68k, mips/mipsel, PowerPC, +SH, SPARC, and v850 processors. +</longdescription> +<use> + <flag name='rpc'>Enable sun nis/rpc support (you should use libtirpc though)</flag> + <flag name='ssp'>Force the use of ssp to be built into a hardened uclibc setup</flag> + <flag name='savedconfig'>Adds support for user defined configs</flag> + <flag name='uclibc-compat'>Build uclibc with backwards compatible + options</flag> + <flag name='wordexp'>Add support for word expansion (wordexp.h)</flag> +</use> +</pkgmetadata> diff --git a/sys-libs/uclibc/uclibc-0.9.33.9999.ebuild b/sys-libs/uclibc/uclibc-0.9.33.9999.ebuild new file mode 100644 index 0000000..2be3c93 --- /dev/null +++ b/sys-libs/uclibc/uclibc-0.9.33.9999.ebuild @@ -0,0 +1,334 @@ +# Copyright 1999-2013 Gentoo Foundation +# Distributed under the terms of the GNU General Public License v2 +# $Header: /var/cvsroot/gentoo-x86/sys-libs/uclibc/uclibc-9999.ebuild,v 1.6 2013/05/19 05:36:27 vapier Exp $ + +inherit eutils flag-o-matic multilib toolchain-funcs savedconfig +EGIT_BRANCH="0.9.33" +EGIT_REPO_URI="git://git.busybox.net/uClibc" +inherit git-2 + +export CBUILD=${CBUILD:-${CHOST}} +export CTARGET=${CTARGET:-${CHOST}} +if [[ ${CTARGET} == ${CHOST} ]] ;
