Before being able to compile the C compiler itself, we will have to start compiling the cross binutils (these include assembler, linkers and some additional tools) for the  EmotionEngine Processor (the main processor of the PS2). Just follow this small step-by-step tutorial and everything should work out !

• Download the following patch for the binutils toolchain (you should download them to the directory where you put the sourcetree tarballs), which enables the PS2 target configurations:
  
  binutils-2.13.2.1-EE.diff.gz
  
• Apply the patch to your binutils sourcetree (unzip them and then patch the sourcetree):
  
  gunzip binutils-2.13.2.1-EE.diff.gz
  patch -p0 <binutils-2.13.2.1-EE.diff
  
  NOTE:
  You have to be in the /GCC-PS2/ directory for these patches to work
  
• Now, set the needed environment variables in your shell with the following commands:
  
  target=ee
  prefix=/usr/local/ps2/$target
  binaries=$prefix/bin
  PATH=$binaries:$PATH
  
  NOTE:
  With these current compiler sources you are not able to produce big-endian binaries for the target mips64r5900-sce-elf (which I had in these guides prior)

• Change to your BUILD-BINUTILS directory
  
  cd /gcc/build-binutils

• Configure your makefile so that it reflects your TARGET and DIRECTORIES
  
  ../binutils-2.13.2.1/configure --target=$target --prefix=$prefix
  
  (as usual with compiling compilers this might take some time depending on your build machine)
  
  
• Start the make-procedure including install
  
  make all install
  
  
• Also to be able to use the binutils and compilers we have to add the directory to our path in either .profile or .bashrc add the following line: (this line puts both the binutils and gcc into your path)
  
  PATH=/usr/local/ps2/mips64r5900-sce-elf/bin:$PATH
  
  NOTE: If you used an other path in prefix. Please add your own path to your .bashrc or .profile !
  

Now you have your EE-BINUTILS sitting in /usr/local/ps2/ee/bin (or any other path you defined in $prefix) . And are ready to comile the remaining parts of the toolchain.
