Now that we used the preliminary GCC for compilation of newlib we can finally compile the complete GCC package (including GCC and G++). This compiler will then be used for the actual Dreamcast compilation.

• Set the needed environment variables in your shell with the following commands:
  (you should have already set them if you're going step-by-step through the SH4 toolchain guide)
  
  target=sh-elf
  prefix=/usr/local/dc/$target
  binaries=$prefix/bin
  PATH=$binaries:$PATH
  
  
• Change to your BUILD-GCC directory
  
  cd /gcc/build-gcc
  
  
• Clean the build directory
  
  make clean
  
  
• Configure your makefile so that it reflects your TARGET and DIRECTORIES
  
  ../gcc-3.0.3/configure --target=$target --prefix=$prefix --without-headers --with-newlib --enable-languages=c,c++
  
  
• Start the make-procedure including install
  
  make all install
  
  (this takes even longer than building the preliminary GCC compiler, be prepared to drink a tea or two !)

Now you have your final SH4-GCC Compilter sitting in /usr/local/dc/sh-elf/bin.
