After we successfully compiled the binutils for the SH4 now comes the compiler we need for compiling the Newlib library for the SH4 target. (we will compile the GCC a second time for the final Dreamcast target).

• 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
  
  
• 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
  
  (As withbuilding the binutils this takes some time.. one difference... it takes longer ;)
  
  
• Start the make-procedure including install
  
  make all install
  
  (this again takes a bit longer than before)
  

Now you have our preliminary SH4-GCC Compiler sitting in /usr/local/dc/sh-elf/bin.

NOTE:
The compiler binaries resulting from this step are only used for compilation of the Newlib !! The real GCC (with C++ support) will be compiled after newlib !
