After we successfully built the binutils and the GCC for the SH4 now comes the newlib libraries we may need!

• 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-NEWLIB directory
  
  cd /gcc/build-newlib
  
  
• Configure your makefile so that it reflects your TARGET and DIRECTORIES
  
  ../newlib-1.9.0/configure --target=$target --prefix=$prefix
  
  (and finally here we go with the longest configuration time <g> ;)
  
  
• Without further changes make the project
  
  make all install \
  CC_FOR_TARGET=$binaries/${target}-gcc \
  AS_FOR_TARGET=$binaries/${target}-as \
  LD_FOR_TARGET=$binaries/${target}-ld \
  AR_FOR_TARGET=$binaries/${target}-ar \
  RANLIB_FOR_TARGET=$binaries/${target}-ranlib
  

NOTE:
The backslashes just tell the shell that the next line still belongs to the same command. So you may also type it all in one line leaving the backslashes out.

That is was for the compiling part of the SH4 newlib.
