Compilation of the IOP toolchain is almost the same as comiling the EE toolchain. Since the IOP target already is a standard target of the GCC compiler we don't have any patches to apply.

• Set the needed environment variables in your shell with the following commands:
  
  target=mipsel-scei-elfl
  prefix=/usr/local/ps2/$target
  binaries=$prefix/bin
  PATH=$binaries:$PATH
  
  
• Change to your BUILD-BINUTILS directory
  
  cd /gcc/build-binutils
  
  
• In case you're compiling the IOP just after the EE toolchain clean up
  
  make clean
  
  
• Configure your makefile so that it reflects your TARGET and DIRECTORIES
  
  ../binutils-2.13.2.1/configure --target=$target --prefix=$prefix
  
  
• Start the make-procedure including install
  
  make all install

Now you have your PS2�EInput/Output Processor GCC Compiler sitting in /usr/local/ps2/mipsel-scei-elfl/bin.

HINT:
As with the EE tools also for some IOP tools it is recommended to create some symbolic links. So you should go to your target directory (if you followed the tutorial it's /usr/local/ps2/mipsel-scei-elfl) and execute the following commands::

ln -s mipsel-scei-elfl-gcc iop-gcc
ln -s mipsel-scei-elfl-ar iop-ar
ln -s mipsel-scei-elfl-ld iop-ld

In case these are not enough you might link all the other IOP tools as well !
