Cross Compiling
This page shows how to cross compile for CellBE/ppc64
Gentoo
Server: Emerge distcc crossdev & env-update & source /etc/profile & crossdev -t powerpc64-unknown-linux-gnu
Client: http://www.gentoo.org/doc/en/cross-compiling-distcc.xml (Because it's much better written than anything I could do)
Ubuntu/Debian
Install required packages
sudo apt-get install build-essential gawk bison flex automake libtool cvs lzma ncurses-dev texinfo patch g++ gcj
Create directories and compile crosstool
mkdir /home/user/crosstool mkdir /home/user/kernel mkdir -p /home/user/toolchain/powerpc 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 the enviromental variable to bash
sudo gedit /etc/bash.bashrc
Add the following line at the end of the file
"export PATH="${PATH}:/home/user/crosstool/bin/"
Download graf_chokolo's kernel
cd /home/user/kernel wget -O linux-2.6.tar.gz http://git.dukio.com/gitweb.cgi?p=linux-2.6\;a=snapshot\;h=HEAD\;sf=tgz
Copy the sample configuration file and modify it
cp /home/user/crosstool/lib/ct-ng-1.10.0/samples/powerpc64-unknown-linux-gnu/* /home/user/toolchain/powerppc/ mv crosstool.config .config cd /home/user/toolchain/powerppc/ ct-ng menuconfig
I've added graf_chokolos kernel
- Operating System -> Linux Kernel version -> custom tarball
- Operating System -> Path to custom tarball -> /home/user/kernel/linux-2.6.tar.gz
or
Start from scratch and configure the toolchain the way you want
cd /home/user/toolchain/powerppc/ ct-ng menuconfig
Compile ppc64 toolchain
unset LD_LIBRARY_PATH LIBRARY_PATH CPATH export LD_LIBRARY_PATH LIBRARY_PATH CPATH ct-ng build
Wait for some time until it finishes compiling
Testing if your toolchain works properly
export PATH="${PATH}:/home/user/x-tools/powerpc64-unknown-linux-gnu/bin/"
powerpc64-unknown-linux-gnuspe-gcc test.c -o test
