Building a cross compiler, linker and bootstrap compiler

Now, we're ready to compile our cross compiler, linker and bootstrap compiler. The first step is the build of the binutils-2.11.2. This package contains programs for archiving (ar), archive indexing (ranlib) and much more essential:

$ cd ../..
$ cd BUILD
$ tar -xvzf ../SRC/binutils-2.11.2.tar.gz -C .
$ patch -p0 < ../SRC/binutils-2.11.2-sh-linux.diff
$ mkdir build-binutils
$ cd build-binutils
$ ../binutils-2.11.2/configure --target=$TARGET \
  --prefix=$PREFIX
$ make all install
$ cd ..

Following, we're able to build the GNU Compiler Collection:

$ tar -xvzf ../SRC/gcc-3.0.1.tar.gz -C .
$ patch -p0 < ../SRC/gcc-3.0.1-sh-linux.diff
$ mkdir build-gcc
$ cd build-gcc
$ ../gcc-3.0.1/configure --target=$TARGET \
  --prefix=$PREFIX --without-headers \
  --with-newlib --disable-shared \
  --enable-languages=c
$ make all-gcc install-gcc
$ cd ..

The configure - script configures this package for the SEGA Dreamcast only with the specified (only the C language) compiler and their runtime libraries, --without-headers prohibits the use of cross compiler header files (they actually don't exist!) and the use of the newlib C - library as the target C - library. This library will be replaced by uClibc in a later stage.
