===Know your host System===
To be improve the building time it is a good idea to know how many cores your processor has and have that number of concurrent jobs.


To know how many cores you have available use :
Install required packages
<pre>
sudo apt-get install build-essential gawk bison flex automake libtool cvs lzma ncurses-dev
sudo apt-get install texinfo patch g++ gcj
</pre>


{{keyboard|content=<syntaxhighlight lang="bash">grep -c '^processor' /proc/cpuinfo</syntaxhighlight>}}
Create directories and compile crosstool
 
<pre>
This will be used later on while building the toolchain ct-ng build.#number of cores and while compiling export CONCURRENCY_LEVEL=#number of cores.
 
Example for a quadcore system :
 
{{keyboard|content=<syntaxhighlight lang="bash">
ct-ng build.4
CONCURRENCY_LEVEL=4
</syntaxhighlight>}}
 
 
===Installing Cross Tool===
 
Install required packages :
{{keyboard|content=<syntaxhighlight lang="bash">sudo apt-get install build-essential gawk bison flex automake libtool cvs lzma ncurses-dev texinfo patch g++ gcj mercurial git-core</syntaxhighlight>}}
 
Add the enviromental variable to bash :
{{keyboard|content=<syntaxhighlight lang="bash">sudo vi /etc/bash.bashrc</syntaxhighlight>}}
or
{{keyboard|content=<syntaxhighlight lang="bash">vi /home/user/.bashrc</syntaxhighlight>}}
 
 
Add the following lines at the end of the file :
 
{{keyboard|content=<syntaxhighlight lang="bash">
export PATH="${PATH}:/home/user/crosstool/bin/"
export PATH="${PATH}:/home/user/x-tools/powerpc64-unknown-linux-gnu/bin/"
export CONCURRENCY_LEVEL=#number
</syntaxhighlight>}}
 
 
Create directories and compile crosstool :
 
{{keyboard|content=<syntaxhighlight lang="bash">
mkdir /home/user/crosstool
mkdir /home/user/crosstool
mkdir /home/user/kernel
mkdir /home/user/kernel
mkdir -p /home/user/toolchain/powerpc
mkdir -p /home/user/toolchain/powerpc
hg clone http://crosstool-ng.org/hg/crosstool-ng
tar xvjf crosstool-ng-1.10.0.tar.bz2
cd crosstool-ng
cd crosstool-ng-1.10.0/
./configure --prefix=/home/user/crosstool
./configure --prefix=/home/user/crosstool/
make && make install
make && make install
</syntaxhighlight>}}
</pre>

===Patching crosstool===
Add enviromental variable
 
NOTE : MAYBE THIS PATCHING STEP IS USELESS WITH LASTEST CROSSTOOL-NG REVISION
 
For some reason, the compiler removes the symbolic links for lib64.
 
The following patch corrects this behaviour allowing the toolchain to work properly without further modifications.
 
====Required Patch====
 
save the following file as """important.patch""" in home/user/crosstool/lib/ct-ng-1.10.0/scripts/build


<pre>
<pre>
diff --git a/scripts/build/internals.sh b/scripts/build/internals.sh
sudo gedit /etc/bash.bashrc

'''Wait for some time until it finishes compiling'''

===Testing if your toolchain works properly===
 
{{keyboard|content=<syntaxhighlight lang="bash">
export PATH="${PATH}:/home/user/x-tools/powerpc64-unknown-linux-gnu/bin/"
powerpc64-unknown-linux-gnuspe-gcc test.c -o test
</syntaxhighlight>}}
 
More info: http://www.ibm.com/developerworks/linux/tutorials/l-embedded-distro/section3.html
 
===Cross compiling openssl===
 
Download openssl sources
{{keyboard|content=<syntaxhighlight lang="bash">wget http://www.openssl.org/source/openssl-0.9.8g.tar.gz</syntaxhighlight>}}
 
unpack the sources :
{{keyboard|content=<syntaxhighlight lang="bash">tar -zxvf openssl-0.9.8g.tar.gz</syntaxhighlight>}}
 
Go to openssl source path :
{{keyboard|content=<syntaxhighlight lang="bash">cd openssl-0.9.8g/</syntaxhighlight>}}
 
Change the following lines in the Makefile :
 
<pre>
INSTALLTOP= /home/user/x-tools/powerpc64-unknown-linux-gnu/powerpc64-unknown-linux-gnu/sysroot/usr
OPENSSLDIR= /home/user/x-tools/powerpc64-unknown-linux-gnu/powerpc64-unknown-linux-gnu/sysroot/usr
CC= powerpc64-unknown-linux-gnu-gcc
AR= powerpc64-unknown-linux-gnu-ar $(ARFLAGS) r
RANLIB= powerpc64-unknown-linux-gnu-ranlib
</pre>
</pre>


Finally :
=Wait for some time until it finishes compiling=
{{keyboard|content=<syntaxhighlight lang="bash">make</syntaxhighlight>}}
 
 
===Cross compiling graf_chokolo's tools===
 
Make sure you have a working toolchain and openssl installed
 
Comment the current compiler and add your cross compiler in our case "powerpc64-unknown-linux-gnu-gcc" :


Trying if your toolchain works properly
<pre>
<pre>
#CC=gcc
export PATH="${PATH}:/home/user/toolchain/x-tools/powerpc64-unknown-linux-gnuspe/bin/"
CC=powerpc64-unknown-linux-gnu-gcc
powerpc64-unknown-linux-gnuspe-gcc test.c -o test
</pre>
</pre>


Finally :
More info: http://www.ibm.com/developerworks/linux/tutorials/l-embedded-distro/section3.html
 
{{keyboard|content=<syntaxhighlight lang="bash">make</syntaxhighlight>}}
 
You can find graf_chokolo tools and scripts here :
 
http://git-hacks.com/linux-ps3
 
===Compiling graf_chokolo's kernel and making a deb package===
 
Go to the directory where you saved your kernel, untar it and go to the kernel source directory :
{{keyboard|content=<syntaxhighlight lang="bash">
cd /home/user/kernel
tar xfvz linux-2.6.tar.gz
cd linux-2.6
</syntaxhighlight>}}
 
It is a good measure to clean the source directory :
{{keyboard|content=<syntaxhighlight lang="bash">
make clean
make-kpkg clean
</syntaxhighlight>}}
 
Export set ARCH=powerpc
And set the right number of concurrent jobs to be done this is used to improve the building time :
 
{{keyboard|content=<syntaxhighlight lang="bash">
export ARCH=powerpc
export CONCURRENCY_LEVEL=4
</syntaxhighlight>}}
 
Use graf_chokolo config file :
{{keyboard|content=<syntaxhighlight lang="bash">
cp ps3_linux_config .config
make oldconfig
</syntaxhighlight>}}
 
You can customize your by using make menuconfig.
 
Now lets compile and package our kernel :
 
{{keyboard|content=<syntaxhighlight lang="bash">make-kpkg --arch=powerpc --cross-compile=powerpc64-unknown-linux-gnu- --rootcmd=fakeroot --initrd --append-to-version=-graf kernel_image kernel_source kernel_headers</syntaxhighlight>}}
