Cross-Compiled Linux From Scratch - Version 1.0.0rc1-x86_64-Pure64

Chapter 6. Constructing a Temporary System

6.3. Binutils-2.17

The Binutils package contains a linker, an assembler, and other tools for handling object files.

6.3.1. Installation of Binutils

To make sure that the proper syntax is used for a couple of tools, apply the following patch: 

patch -Np1 -i ../binutils-2.17-posix-1.patch

The Binutils documentation recommends building Binutils outside of the source directory in a dedicated build directory: 

mkdir -v ../binutils-build
cd ../binutils-build

Prepare Binutils for compilation: 

CC="${CC} ${BUILD64}" \
     ../binutils-2.17/configure --prefix=/tools \
     --build=${LFS_HOST} --host=${LFS_TARGET} --target=${LFS_TARGET} \
     --disable-nls --enable-shared --enable-64-bit-bfd \
     --disable-multilib

The meaning of the new configure options:

CC="${CC} ${BUILD64}"

Tells the compiler to use our 64-bit build flags.

Compile the package: 

make configure-host
make

Install the package: 

make install

Details on this package are located in Section 10.8.2, “Contents of Binutils.”
