Building ARM Toolchain

Originally this was a complete walkthrough the compilation and installation process of the ARM Toolchain. Now there is a script called Summon ARM Toolchain that does everything automatically. Apart from the standard development tools linux users should install the following extra packages: libgmp3-dev and libmpfr-dev

For Debian/Ubuntu: > apt-get install libgmp3-dev libmpfr-dev

Or use build-dep to automatically grab everything needed to compile gcc: > apt-get build-dep gcc-4.4

or on Maverick: > apt-get build-dep gcc-4.5

For Cygwin on Windows you need the following packages:
 * automake
 * autoconf
 * make
 * git
 * wget
 * termcap
 * libmpc-devel
 * libmpfr-devel
 * libgmp-devel
 * libncurses-devel
 * libtool
 * patch

Also binutils 2.19.1 needs a patch as described here: http://www.mail-archive.com/bug-binutils@gnu.org/msg06475.html. The current version of summon-arm-toolchain uses a newer binutils version that doesn't require the patch.

Now you only have to:

> wget http://github.com/esden/summon-arm-toolchain/raw/master/summon-arm-toolchain

And run the script: > ./summon-arm-toolchain

This will download all necessary sources and build all the toolchain parts.

After that you should have a complete smooth ARM toolchain that should work with STM32 and LPC21.

This script should work on Linux and Mac OS X and is partly tested on CygWin on Windows 7 (additional patches welcome).

Have fun.
