Xenon Toolchain

Windows

Installing Cygwin

1. Download Cygwin. Once it's done, run the installer. Set the Install Directory to C:\Cygwin, or what ever your root drive path is.
2. When prompted for a server, select anyone, they all have the same packages, but I would recommend xmission.
3. Make sure you install the necessary devs libs:

GCC 
Make 
Git 
build-essential 
texinfo 
Etc.

Linux

Prerequisites

libgmp3-dev
libmpfr-dev
texinfo
git-core

Mac OS X

Prerequisites

1. Install Xcode.
2. Install macports, then "sudo port install mpfr gmp git-core wget"
3. sudo mkdir /usr/local/xenon; sudo chown -R $USER /usr/local/xenon
4. Do the "Building the Toolchain" stuff from below.

If you're running Xcode 3.2, get Apple to fix this bug. Workaround is to compile until it fails with the "duplicate symbol" error (check build.log), then do the mentioned workaround in gcc-4.4.0/gcc directory (changing Make-lang.in), then disable the rebuild of binutils, gcc (first stage) and newlib by setting

BUILD_BINUTILS=false
BUILD_GCC=false
BUILD_NEWLIB=false
BUILD_GCC_SECOND=true

in the build-xenon-toolchain. Then retry the build. It should finish the build.

Building the Toolchain

Run the following commands through the cygwin Bash console:

git clone git://free60.git.sourceforge.net/gitroot/free60/free60
cd free60/toolchain
./build-xenon-toolchain toolchain

The toolchain should start building (Note: This might take some time).
