Welcome to the LinuxDevTools web

Linux Development Tools

GNU development tools are the primary tools used to build GNU/Linux systems. CodeSourcery LLC., in partnership with ARM, Ltd., develop improvements to the GNU GCC Toolchain for ARM processors and provides regular, precompiled and tested tool chain releases. More information and pre-built snapshots can be found at the following location. These include support for ARM cores up to and including the ARMv7 architecture, Thread-Local Storage (TLS) as well as Native POSIX Threads Library (NPTL) for ARM.

Application Binary Interface for the ARM® Architecture

The Application Binary Interface (ABI) for the ARM® Architecture is a collection of standards, some open and some specific to the ARM architecture. The standards regulate the inter-operation of binary code, development tools, and a spectrum of ARM core-based execution environments from bare metal to platform operating systems such as ARM Linux.

Version 1.0 of the base standard was principally concerned with governing inter-operation between relocatable files. Version 2.0 also sets standards for executable files. More detailed documentation can be found at the following location.

The GNU GCC tool chain (versions 3.4.3 onwards) conforms to the ABIv2 standard and can inter-operate with other proprietary tool chains which also comply with this standard. Pre-built snapshots of of the GNU tools can be found here and here.

ARM released Application Note 178 on ARM support pages to give more information on how to produce executables from objects compiled with GNU tools and ARM RealView Tools.

Cross Development

Scratchbox

This link has details of how to compile Debian packages for the ABI using Scratchbox with a Qemu qemu-system-arm target.

• OpenEmbedded - a buildsystem which generated toolchains, packages and complete filesystems from scratch
• PTXdist - a buildsystem, based on Kconfig and simple makefiles. PTXdist fits on one disk (plus bugfixing patches for upstream packets).
