# Barebones [ i686-elf / ARMv7-eabi / MIPS ] cross-compiler & toolchain

This repo provides a stand-alone barebones gcc cross-compiler and toolchain for
the following target architectures:

* i686 (32-bit ELF),
* ARMv7 (eabi),
* MIPS

There are two platform flavors, 32- and 64-bit depending on your host linux environment.
The correct one is automatically chosen when the `setenv.sh` script is run.

## Provided versions

| Package  | Version |
|----------|---------|
| binutils | 2.27    |
| gcc      | 6.2.0   |
| gmp      | 6.1.1   |
| isl      | 0.17    |
| libiconv | 1.14    |
| mpc      | 1.0.3   |
| mpfr     | 3.1.4   |

## Setup details

Git clone this repository, then run the `setenv.sh` script to configure your PATH:

    $ git clone https://github.com/rm-hull/barebones-toolchain.git
    $ cd barebones-toolchain
    $ . ./setenv.sh

Check that it worked:

    6.2.0

If you want to use an older version, checkout with that specific tag:

    $ git checkout 4.9.2

## TODO

* ~~Build 64-bit platform tools for ARMv7 target~~
* ~~Build 32- & 64-bit platform tools for MIPS target~~

## Acknowledgements

Built from instructions here: http://wiki.osdev.org/GCC_Cross-Compiler.

ARM build was exactly the same except: `export TARGET=arm-none-eabi`.
Likewise MIPS build was exactly the same except: `export TARGET=mips`.
