Target compatibility
--------------------
The default configuration is:
 * 2.1.0 2014.02
 * A GCC 4.8 series libgcc and libstdc++

Host compatibility
------------------
The Linux version is supported on:
 * Ubuntu 10.04.3 and later
 * Debian 6.0.2
 * Fedora 16
 * openSUSE 12.1
 * Red Hat Enterprise Linux Workstation 5.7 and later

and should run on any Linux Standard Base 3.0 compatible
distribution.  Installing the LSB depends on the distribution:

 * On Ubuntu or Debian, run `sudo apt-get install lsb`
 * On Fedora 16, run `sudo yum install redhat-lsb.i686`
 * On openSUSE 12, run `sudo zypper install lsb.i586`
 * Red Hat 5 is LSB compatible by default
 * For other distributions, please see the distribution documentation

This package contains 32 bit executables that also run on 64 bit
hosts.  In some cases you may need to install the 32 bit support
libraries.  On Ubuntu or Debian run `sudo apt-get install ia32-libs`.
For other distributions, please see the distribution documentation.

The Windows version is supported on:
 * Windows XP Pro SP3
 * Windows Vista Business SP2
 * Windows 7 Pro SP1

on both 32 bit and 64 bit hosts.  No other files are required.
For best results, make sure there are no spaces in the directory name.

Source
------
This package was built using an Ubuntu 10.04 i686 host, crosstool-NG,
and the source tarballs included in the `src` archive.

The following instructions are untested.  Patches are welcome!

To reproduce this build:
 * Install the build dependencies:
  * apt-get build-dep gcc binutils gdb
  * apt-get install lsb lsb-build-cc3 lsb-appchk3 ccache
  * apt-get install gcc-mingw32 gcc-4.1 g++-4.1 gcc-4.1-multilib g++-4.1-multilib
  * apt-get install texlive flip
 * Building requires /bin/sh to be bash. See http://crosstool-ng.org/ for more
 * Download the `src` archive
 * Download and extract the crosstool-NG tarball
 * Change to the crosstool-NG directory
 * Extract the `src` archive giving `tarballs/binutils-*` and similar
 * Run `make -f contrib/linaro/build.mk TARGETS=arm-none-eabi`

The builds will end up in `builds/$target-$host`.  See
`contrib/linaro/build.mk` for more.

Alternatively, you can build directly using the sample configurations.
See the crosstool-NG documentation and `samples/linaro-arm-linux-gnueabihf`.

A patched version of the LSB is used to work around configuration and
host GCC compatibility issues.  `build.mk` builds and uses this
automatically.  See `contrib/linaro/lsb/make-lsb.sh` for manual builds.
