Cross Compiling

Cross Compiling

This page shows how to cross compile for cellBE/ppc

Install required packages

sudo apt-get install build-essential gawk bison flex automake libtool cvs lzma ncurses-dev
sudo apt-get install texinfo patch g++ gcj

Create directories and compile crosstool

mkdir /home/user/crosstool
mkdir /home/user/kernel
mkdir -p /home/user/toolchain/mips
tar xvjf crosstool-ng-1.10.0.tar.bz2
cd crosstool-ng-1.10.0/
./configure --prefix=/home/user/crosstool/
make && make install

• /home/user/crosstool-ng-1.10.0/ -> ""crostool-ng sources""
• /home/user/crosstool/ -> ""Crosstool install directory with binaries""
• /home/user/toolchain/ -> ""Directory where the binary will be installed""
• /home/user/toolchain/powerpc/ -> ""Crosstool files generated in this tutorial for powerpc""
• /home/user/toolchain/x-tools/ -> ""generated toolchain""
• /home/user/kernel -> ""Place were graf_chokolo's linux kernel tarball will be saved""

Add enviromental variable

sudo gedit /etc/bash.bashrc

Add the following line at the end of the file

"export PATH="${PATH}:/home/user/crosstool/bin/"

Download graf_chokolo's kernel

cd /home/user/kernel
wget -O linux-2.6.tar.gz http://git.dukio.com/gitweb.cgi?p=linux-2.6\;a=snapshot\;h=HEAD\;sf=tgz

Copy the configuration file and modify it

cp /home/user/crosstool/lib/ct-ng-1.10.0/samples/powerpc64-unknown-linux-gnu/* /home/user/toolchain/powerppc/
mv crosstool.config .config
cd /home/user/toolchain/powerppc/
ct-ng menuconfig

I added graf_chokolos kernell 

*Operating System -> Linux Kernel version -> custom tarball
*Operating System -> Path to custom tarball -> /home/user/kernel/linux-2.6.tar.gz

or
Configure the toolchain the way you want 
cd /home/user/toolchain/powerppc/
ct-ng menuconfig
