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

1. 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
2. make install
   }}}
