Replicant

= Replicant Native 64 Bit Build =

This page explains how to configure a 64b native build. The goal is to build Replicant without the need of 32b compatibility libs and to produce 64b host binaries (adb, fastboot, emulator, etc).

'''Note: This is a quite experimental and long process. Although you don't risk any damage to your computer while trying to set this up, you should better already have basic knowledge about building gcc, dealing with Makefiles and other related stuff, since some errors may append.''' 

Note for the whole page: when a line is prefixed with #, that means that you have to run the command as root. Don't copy the # on the shell. 

== Required tools ==

(Basic building tools)

== Building the toolchain ==

First, you'll need to download binutils, gcc-core, gcc-g++, gmp and mpfr:

{{{

mkdir replicant-toolchain

cd replicant-toolchain

wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.tar.bz2

wget http://ftp.gnu.org/gnu/gcc/gcc-4.4.3/gcc-core-4.4.3.tar.bz2

wget http://ftp.gnu.org/gnu/gcc/gcc-4.4.3/gcc-g++-4.4.3.tar.bz2

wget http://ftp.gnu.org/gnu/gmp/gmp-4.3.2.tar.bz2

wget http://ftp.gnu.org/gnu/mpfr/mpfr-3.0.1.tar.bz2

tar -xf binutils-2.21.tar.bz2

tar -xf gcc-core-4.4.3.tar.bz2

tar -xf gcc-g++-4.4.3.tar.bz2

tar -xf gmp-4.3.2.tar.bz2

tar -xf mpfr-3.0.1.tar.bz2

mv gmp-4.3.2 gcc-4.4.3/

mv mpfr-3.0.1 gcc-4.4.3/

}}}

Now, you have to build binutils and gcc for the arm-eabi target:

{{{

cd binutils-2.21

./configure --target=arm-eabi --prefix=/usr/local

make

# make install

cd ../gcc-4.4.3

mkdir build

cd build

../configure --target=arm-eabi --prefix=/usr/local --with-mpfr=../mpfr-3.0.1/ --with-gmp=../gmp-4.3.2/ --enable-shared

make

# make install

}}}
