Summary: A minimal libc subset for use with initramfs. Name: klibc Version: 0.198 Release: 1 License: BSD/GPL Group: Development/Libraries URL: http://www.zytor.com/mailman/listinfo/klibc Source: http://www.kernel.org/pub/linux/libs/klibc-%{version}.tar.gz BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-buildroot BuildRequires: kernel-source >= 2.6.0 Packager: H. Peter Anvin Prefix: /usr Vendor: Starving Linux Artists %description %{name} is intended to be a minimalistic libc subset for use with initramfs. It is deliberately written for small size, minimal entanglement, and portability, not speed. It is definitely a work in progress, and a lot of things are still missing. %package kernheaders Summary: Kernel headers used during the build of klibc. Group: Development/Libraries %description kernheaders This package contains the set of kernel headers that were required to build %{name} and the utilities that ship with it. This may or may not be a complete enough set to build other programs that link against %{name}. If in doubt, use real kernel headers instead. %package utils Summary: Small statically-linked utilities built with klibc. Group: Utilities/System %description utils This package contains a collection of programs that are statically linked against klibc. These duplicate some of the functionality of a regular Linux toolset, but are typically much smaller than their full-function counterparts. They are intended for inclusion in initramfs images and embedded systems. %prep %setup -q cp -as /usr/src/linux-`rpm -q kernel-source | tail -1 | cut -d- -f3-` ./linux make -C linux defconfig ARCH=%{_target_cpu} make -C linux prepare ARCH=%{_target_cpu} # Deal with braindamage in RedHat's kernel-source RPM rm -f linux/include/linux/config.h cat < linux/include/linux/config.h #ifndef _LINUX_CONFIG_H #define _LINUX_CONFIG_H #include #endif EOF mkdir -p %{buildroot} %build make ARCH=%{_target_cpu} %install rm -rf %{buildroot} dest=%{buildroot}/%{prefix} lib=$dest/%{_lib}/klibc inc=$dest/include/klibc exe=$dest/libexec/klibc doc=$dest/share/doc/%{name}-%{version} udoc=$dest/share/doc/%{name}-utils-%{version} # First, the library. install -dD -m 755 $lib $inc/kernel $exe $doc $udoc install -m 755 klibc/klibc.so $lib install -m 644 klibc/libc.a $lib install -m 644 klibc/crt0.o $lib install -m 644 klibc/libc.so.hash $lib ln $lib/klibc.so $lib/libc.so ln $lib/klibc.so $lib/klibc-$(cat $lib/libc.so.hash).so # Next, the generated binaries. # These are currently static binaries, should we go for shared? install -m 755 ash/sh $exe install -m 755 gzip/gzip $exe ln $exe/gzip $exe/gunzip ln $exe/gzip $exe/zcat install -m 755 ipconfig/ipconfig $exe install -m 755 kinit/kinit $exe install -m 755 nfsmount/nfsmount $exe install -m 755 utils/static/* $exe # The docs. install -m 444 README $doc install -m 444 klibc/README $doc/README.klibc install -m 444 klibc/arch/README $doc/README.klibc.arch install -m 444 gzip/COPYING $udoc/COPYING.gzip install -m 444 gzip/README $udoc/README.gzip install -m 444 ipconfig/README $udoc/README.ipconfig install -m 444 kinit/README $udoc/README.kinit # Finally, the include files. bitsize=$(make --no-print-directory -C klibc bitsize ARCH=%{_target_cpu}) cp --parents $(find klibc/include \( -name CVS -o -name SCCS \) -prune \ -o -name '*.h' -print) $inc mv $inc/klibc $inc/klibc.$$ mv $inc/klibc.$$/include/* $inc mv $inc/bits$bitsize/bitsize $inc rm -rf $inc/klibc.$$ $inc/bits[0-9]* pushd klibc/arch/%{_arch}/include cp --parents -f $(find . \( -name CVS -o -name SCCS \) -prune \ -o -name '*.h' -print) $inc popd # Yeugh.
