For several years CodeSourcery (now Mentor Graphics) maintained and released the GCC for ARM compiler binaries, bundled with an easy to use installer, under the name Codesourcery G++ Lite. Unfortunately, their website now states that “Sourcery CodeBench Lite releases for ARM EABI, ARM GNU/Linux, ARM AARCH64-Linux, IA32/IA64 GNU/Linux and ELF are no longer available”.

Fortunately, the ARM organization itself is actively maintaining and enhancing the GCC compiler for the ARM architecture. At regular intervals they release pre-built binaries of the toolchain under the name GCC ARM Embedded

Several OpenBLT demo programs that target microcontrollers with an ARM core, make use of the Codesourcery G++ Lite toolchain. You can still find a download link to a working version of the toolchain on the page that describes the demo specifics. However, is it recommended to switch to the GCC ARM Embedded toolchain.

This page describes how to upgrade

To compile the demo programs with Codesourcery G++ Lite (Target OS EABI), you can invoke the make utility from the command line.
