This is an old revision of the document!
In this document I will describe how to build a toolchain for ARM.
setup build environment
In this document we will install the toolchain in the users home directory under $HOME/arm-elf.
Installation will take place in /tmp/toolchain.
$ mkdir -p /tmp/toolchain/src
$ mkdir -p /tmp/toolchain/arm-elf
$ mkdir -p $HOME/arm-elf/bin
$ export PATH=$HOME/arm-elf/bin:$PATH
binutils
Download binutils from http://ftp.gnu.org/gnu/binutils/binutils-2.21.1.tar.gz
$ cd /tmp/toolchain/src
$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.1.tar.gz
$ tar -zxvf binutils-2.21.1.tar.gz
Configure and build.
$ cd /tmp/toolchain/arm-elf
$ mkdir binutils
$ cd binutils
$ ../../src/binutils-2.21.1/configure –prefix=$HOME/arm-elf –target=arm-elf –disable-nls
$ make
$ make install
gcc
newlib
