# E-scripts on the "anatomy" of compiled C programs
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.
#
# This file is at <http://angg.twu.net/e/anatocc.e>

Next, decide where you want to install your toolchain. They generally go in /usr/local/, so I'm going to assume /usr/local/cross-arm for this tutorial. To save
yourself some typing, set this path into a shell variable:
# export TOOLPATH=/usr/local/cross-arm
export TOOLPATH=/tmp/local-cross-arm
mkdir $TOOLPATH/
: Step 1: binutils
This is the easiest step: unpack, configure, build.
$ tar xvfj binutils-2.17.tar.bz2
$ cd binutils-2.17
$ mkdir build
$ cd build
$ ../configure --target=arm-elf --prefix=$TOOLPATH --enable-interwork --enable-multilib
--with-gnu-as --with-gnu-ld --disable-nls
$ make all
$ sudo make install
$ export PATH=${TOOLPATH}/bin:$PATH

There is one difference between an array name and a pointer that must
be kept in mind. A pointer is a variable, so pa=a and pa++ are legal.
But an array name is not a variable; constructions like a=pa and a++
are illegal.
When an array name is passed to a function, what is passed is the
location of the initial element. Within the called function, this
argument is a local variable, and so an array name parameter is a
pointer, that is, a variable containing an address. We can use this
fact to write another version of strlen, which computes the length of
a string.
