We will start by making the binutils-package (this includes assembler, linkers and some additional tools) for the SH4-processor (the Dreamcast main processor). Just follow this small step-by-step tutorial and everything should work out !

• Set the needed environment variables in your shell with the following commands:
  
  target=sh-elf
  prefix=/usr/local/dc/$target
  binaries=$prefix/bin
  PATH=$binaries:$PATH
  
  
• Change to your BUILD-BINUTILS directory
  
  cd /gcc/build-binutils
  
  
• Configure your makefile so that it reflects your TARGET and DIRECTORIES
  
  ../binutils-2.11.2/configure --target=$target --prefix=$prefix
  
  (this step may take quite some time, so enjoy the nice printouts and take a cup of coffee....... or two...)
  
  
• Start the make-procedure including install
  
  make all install
  
  (as with the step above this may take some time... even some more than configuring)
  
  
• 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/dc/sh-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 SH4-BINUTILS sitting in /usr/local/dc/sh-elf/bin (or any other path you defined in $prefix) . And are ready to comile the remaining parts of the toolchain.
