This is the compiler we are using to compile C programs for the graphing calculator. [Link][http://trac.godzil.net/gcc4ti/wiki/Download]. You can download binaries for Mac, Linux and Windows from this website.

OS X:

1. Download gcc4ti-install-osx5.sh [https://dl.dropboxusercontent.com/u/1932295/gcc4ti-install-osx5.sh]

2. Go to terminal, cd to the Downloads directory and run

Windows:

1. Download tigcc here: [http://www.ticalc.org/pub/win/asm/tigcc.zip]

2. Unzip and install

./gcc4ti-install-osx5.sh

This is the emulator we use to test our programs before running them on an actual graphing calculator.

OS X:

1. Install MacPorts [http://www.macports.org/install.php]

2. Install TiEmu3 from MacPorts

sudo port install tiemu3

Windows:

1. Download and install here [http://www.ticalc.org/archives/files/fileinfo/387/38770.html]

Linux:

1. I'm sorry, but you've have to build from source [http://www.ticalc.org/archives/files/fileinfo/387/38771.html]

After installing, download the ROM image for the TI-89 calculator here [https://dl.dropboxusercontent.com/u/1932295/TI89Titanium_OS.89u] and load the image into TiEmu on your first start up.

This program lets you transfer your compiled program from your computer to the calculator. Unfortunately TI only provide OS X and Windows versions.
