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
libmpc-dev
texinfo
git-core
build-essential

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 console your using:

git clone git://github.com/Free60Project/libxenon.git
cd libxenon/toolchain
./build-xenon-toolchain toolchain

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

Full process of installation

To give people a start who are not used to Linux but want to start coding, here it goes. In this example I am refering to Ubuntu/Debian.

First we install dependencies

apt-get install libgmp3-dev libmpfr-dev libmpc-dev texinfo git-core gettext build-essential

Now we create the target directory for the Toolchain & Libxenon and own it by the current user
Note: If your distro has the "su" command to get superuser rights, get superuser before typing the commands in the following block.
Note: If not, append "sudo" before those commands (example: "sudo mkdir -p /usr/local/xenon")

mkdir -p /usr/local/xenon
chown -R your_regular_user:your_regular_user /usr/local/xenon
# exit the superuser-environment now!

Then we grab the toolchain from git and build it

git clone git://github.com/Free60Project/libxenon.git
cd libxenon/toolchain
./build-xenon-toolchain toolchain

Note: If gcc building, 2nd stage, fails for you, do "apt-get install libgmp4-dev" and restart building process.

Note for Ubuntu users: If you encounter in the build.log following error:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.2+ and MPC 0.8.0+.

Do the following:

cd gcc-4.6.1
wget ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2
tar xvjf gmp-5.0.2.tar.bz2 && mv gmp-5.0.2 gmp
wget http://www.multiprecision.org/mpc/download/mpc-0.9.tar.gz
tar xvzf mpc-0.9.tar.gz && mv mpc-0.9 mpc 
wget http://www.mpfr.org/mpfr-current/mpfr-3.0.1.tar.gz
tar xvzf mpfr-3.0.1.tar.gz && mv mpfr-3.0.1 mpfr
cd ..
./build-xenon-toolchain toolchain

At the end of compiling it will tell you to add paths to your ~/.bashrc - that's an improper solution.
Rather do it the following way:

# Get superuser rights first!
touch /etc/profile.d/devkitxenon.sh
chmod +x /etc/profile.d/devkitxenon.sh
# Now open the file and insert the two export lines
nano /etc/profile.d/devkitxenon.sh
# Insert the lines below in the text editor!

export DEVKITXENON="/usr/local/xenon"
export PATH="$PATH:$DEVKITXENON/bin:$DEVKITXENON/usr/bin"

Press Ctrl+O for saving the file and press ENTER if it asks for a filename Press Ctrl+X for closing nano

Have fun compiling your code ;)
