LFS - Binutils


INSTALLING BINUTILS package
Shifted to www.linuxfromscratch.org - Linux From Scratch - version 6.8 (the book was outdated so shifting to the website by the same other) - It starts with installation of binutils and not BASH. no problem though.

The main modifications I made is shifted the sources from /usr/src to a dedicated folder at $LFS/sources
The location where the tools are to be installed is $LFS/tools. A symbolic link is created for the same in the host systems

INSTALLATION OF BINUTILS
check for $LFS, $LFS_TGT else
export LFS=/mnt/lfs
export LFS_TGT=$(uname -m)-lfs-linux-gnu

1. download the Binutils-2.21.tar.gz into the $LFS/sources
2. tar xvzf binutils-2.21.tar.gz - extracts into a folder called binutils-2.21
3. mkdir $LFS/sources/binutils-build
4. cd $LFS/binutils-build
5. ../binutils-2.21/confiure --targer=$LFS_TGT --prefix=/tools --disable-nls --disable-werror
6. make
7. make install

LFS_TGT contains the description of the system. The config.guess inside binutils-2.21 contains information on the description of the machine assumed.
--prefix=/tools - tells the configure script to install in the /tools directory
--disable-werror - prevents build from stopping if there are warnings in host compiler

Cannot run the test scripts now because the testsuite framword (Tcl, Expect and DejaGNU is not available yet).
