This is the **official** cross-compiling method used at **Arch Linux ARM**. If you plan on building a lot of packages and want to speed up the process, the following guide will turn an *x86* Linux computer into an ARM cross-compiler. It's also much easier than most cross-compile setups. This is the **official** cross-compiling method used at **Arch Linux ARM**.

## Introduction ## Introduction
This guide makes use of *distcc* in order to not have to build a full ARM development environment on x86. This guide makes use of *distcc* and *crosstool-NG* in order to not have to build a full ARM development environment on x86.
*distcc* allow us to use network clients to spread the load of the compilation to slaves from a master. For example, an ARM (distcc) master will send its compile jobs to *x86_64* (distccd) clients. The clients don't need to run *archlinux*. *distcc* allow us to use network clients to spread the load of the compilation to slaves from a master. For example, an ARM (distcc) master will send its compile jobs to *x86_64* (distccd) clients that will use *crosstool-NG* toolchain. The clients don't need to run *archlinux*.
As the *distcc* project website states, "distcc does not require all machines to share a filesystem, have synchronized clocks, or to have the same libraries or header files installed." This is particularly advantageous to us since all that is needed is a working cross-compiler for ARM on a faster machine, while controlling the build from an ARM computer that has all of the current libraries and headers.
