You will need:

* An x86 PC running Linux, bash, gcc, GNU make

* The file attached to this message

* The following tarballs, available from FTP sites the world over: binutils-2.10.1.tar.gz, gcc-2.95.3.tar.gz, glibc-2.1.3.tar.gz, glibc-crypt-2.1.tar.gz, glibc-linuxthreads-2.1.3.tar.gz, linux-2.4.3.tar.gz

* 90Mb free disc space, plus another 250Mb for the compilation process

You should:

* Untar armtools.tar.gz to create the 'armtools' directory

* Stick all the tarballs you've collected in that directory

* Edit the PREFIX in the Makefile to dictate where your toolchain ends up (suggestions are in the file)

* Run make. This will build and install your toolchain (so you should run it as a user that can write to $PREFIX). It takes about one trillion cycles (20min on 1GHz).

You will then have an ARM Linux cross-compiler that's the same version as we use for V2.0 car player software. When cross-compiling, add $PREFIX/bin to your path. (Don't do it when you're not cross-compiling, in case you get the wrong cpp.)
