+#define _PAGE_ Building the SH1 cross compiler
+#include "head.t"
+
+<p>
+In this example I will assume that you are running Linux with the bash shell.
+We will only build the C compiler along with the assembler, linker and stuff.
+<h2>Download the source code</h2>
+<p>
+You will need the following archives:
+<ul>
+<li>binutils-2.11.tar.gz (find it at your closest GNU FTP site)
+<li>gcc-3.0.3.tar.gz (find it at your closest GNU FTP site)
+<li>newlib-1.10.0.tar.gz (go to <a href="http://sources.redhat.com/newlib/">the newlib home page</a> for information)
+<li>(optional) gdb-5.1.1.tar.gz (find it at your closest GNU FTP site)
+</ul>
+<h2>Unpack the archives</h2>
+<p>
+<pre>
+ /home/linus> tar zxf binutils-2.11.tar.gz
+ /home/linus> tar zxf gcc-3.0.3.tar.gz
+ /home/linus> tar zxf newlib-1.10.0.tar.gz
+ /home/linus> tar zxf gdb-5.1.1.tar.gz
+</pre>
+<h2>Create the directory tree</h2>
+<p>
+<pre>
+ /home/linus> mkdir build
+ /home/linus> cd build
+ /home/linus/build> mkdir binutils
+ /home/linus/build> mkdir gcc
+ /home/linus/build> mkdir gdb
+</pre>
+<h2>Create the newlib and libgloss links</h2>
+<p>
+The GCC configuration script finds the newlib and libgloss files if they are in the GCC tree. Let's create two soft links.
+<pre>
+ /home/linus> cd gcc-3.0.3
+ /home/linus/gcc-3.0.3> ln -s ../newlib-1.10.0/newlib .
+ /home/linus/gcc-3.0.3> ln -s ../newlib-1.10.0/libgloss .
+</pre>
+<h2>Make up your mind</h2>
+<p>
+Now is the time to decide where you want the tools to be installed. This is
+the directory where all binaries, libraries, man pages and stuff end up when
+you do "make install".
+<p>
+In this example I have chosen "/home/linus/sh1" as my installation directory, or <i>prefix</i> as it is called. Feel free to use any prefix, like
+/usr/local/sh1 for example.
+<h2>Build binutils</h2>
+<p>
+We will start with building the binutils (the assembler, linker and stuff).
+This is pretty straightforward. We will be installing the whole tool chain
+in the /home/linus/sh1 directory.
+<pre>
+ /home/linus> cd build/binutils
+ /home/linus/build/binutils> ../../binutils-2.11/configure --target=sh-elf --prefix=/home/linus/sh1
+ /home/linus/build/binutils> make
+ /home/linus/build/binutils> make install
+</pre>
+<h2>Build GCC</h2>
+<p>
+Now you are ready to build GCC. To do this, you must have the newly built
+binutils in the PATH.
+<pre>
+ /home/linus> export PATH=/home/linus/sh1/bin:$PATH
+ /home/linus> cd build/gcc
+ /home/linus/gcc> ../../gcc-3.0.3/configure --target=sh-elf --prefix=/home/linus/sh1 --with-newlib --enable-languages=c
+ /home/linus/build/binutils> make
+ /home/linus/build/binutils> make install
+</pre>
+<h2>Build GDB</h2>
+<p>
+If you are planning to debug your code with GDB, you have to build it as well.
+<pre>
+ /home/linus> export PATH=/home/linus/sh1/bin:$PATH
+ /home/linus> cd build/gdb
+ /home/linus/gdb> ../../gdb-5.1.1/configure --target=sh-elf --prefix=/home/linus/sh1
+ /home/linus/build/binutils> make
+ /home/linus/build/binutils> make install
+</pre>
+<h2>Done</h2>
+<p>
+If someone up there likes you, you now have a working tool chain for SH1.
+To compile a file with gcc:
+<pre>
+ /home/linus> sh-elf-gcc -c main.o main.c
+</pre>
+Good luck!
+<p>
