  • Using Codewarrior for Macintosh
    CS106B Handout #5M Winter 04-05 January 7, 2005 Using CodeWarrior for Macintosh In CS106, you have the option of writing your programs on the Mac or PC. For the Macintosh environment, you will write your programs using the C++ compiler by Metrowerks called CodeWarrior Professional. The current version of CodeWarrior, Pro 8, has been site-licensed to Stanford and can be downloaded from the Software page on the course web site. CodeWarrior provides a very nice editing environment and debugger, and it is the state-of-the-art C++ compiler for the Mac. One of the consequences of using a state-of-the-art compiler is that the system requirements for CodeWarrior Pro 8 are somewhat high – it requires Mac OS 9.2.2 or later, 700MB of hard drive space, and at least 64 MB of RAM. You also have to have CarbonLib 1.5, since Pro 8 is written for Mac OS X as well. If you have OS X, then you need 128MB of RAM to run CodeWarrior Pro 8, and you don’t need CarbonLib as this is already part of OS X. You can download CarbonLib from Apple—more on this later. Using CodeWarrior at a cluster CodeWarrior is available for use in the Lair (the Tresidder Macintosh cluster), on the Macs in Meyer library, and in the residential computer clusters. Often it will already be in the Applications folder on the machine’s hard disk. If there is a folder there named something like Metrowerks CodeWarrior 8, then the application can be found within that folder.

  • This Introduction to the Metrowerks Codewarrior Software Development Tools
    Tutorial Introduction PURPOSE: - Provides an overview of the Metrowerks CodeWarrior toolset and explains how the toolset is organized and operates OBJECTIVES - Describe the CodeWarrior integrated development environment (IDE) - Identify the components of the CodeWarrior build system. - Identify the hosts on which the IDE executes. - Define a target. CONTENT: - 14 pages - 3 questions LEARNING TIME: - 20 minutes Welcome to this introduction to the Metrowerks CodeWarrior software development tools. This tutorial explains how CodeWarrior combines the programs required to write software into one seamless, integrated work environment. CodeWarrior tools run on several different platforms and can generate machine code for a variety of desktop and embedded systems. Upon completion of this tutorial, you’ll be able to describe the components of the CodeWarrior build system and the general organization of the software package. You’ll also be able to define a target and describe the operating systems that will host the software. 1 What is an IDE? • The IDE consists of tools that are used throughout the software development process. Project Manager Compiler Editor Assembler Search engine Linker Source code browser Debugger GUI designer • The tools are integrated fully and seamlessly. • A single environment is provided for software development. -- consistent operation -- move among all the tools freely -- a non-modal design In the CodeWarrior toolset, the Editor, Compiler, Linker, Debugger, and other software modules operate within an Integrated Development Environment, or IDE. The IDE oversees the control and execution of the tools. It provides an interface to the tools that is consistent and predictable. The operation of the development tools is seamless.

  • For Smartphones?
    15.912 TECHNOLOGY STRATEGY SPRING SEMESTER 2005 FINAL PAPER SHOULD MOTOROLA EMBRACE 100% THE LINUX OPERATING SYSTEM (OS) FOR SMARTPHONES? Silvia Battigelli Alberto Farronato Carlos Mazariegos 15.912 - Technology Strategy Final Paper 1. Introduction In a period when the market for mobile devices is changing and moving towards convergence of multiple products into one single device, it is time for the big players in all related industries to reconsider their strategy to capture more of the value that convergence will create. Motorola, the second largest manufacturer of mobile handsets, recently adopted a new open source OS in a completely new market, such as the one of smartphones in China, and the question is: should they strongly adopt the new standard in all of the new products and in all of the markets? We believe that the answer is yes, and in this paper we will explain why. 2. An Overview of Motorola Motorola was originally founded as the Galvin Manufacturing Corporation in 1928 by Paul V. Galvin and his brother Joseph E. Galvin in Chicago, Illinois. Galvin Manufacturing Corporation's first product was a battery eliminator, a device that allows battery-powered radios to run on standard household electric current. In the 1930’s the company introduced one of the first commercially successful car radios and a single-frequency mobile radio receiver for police broadcasts. The company had just entered into the new field of mobile radio communications with net annual sales of $287,256. In the 1940’s, after Galvin Manufacturing Corporation becomes Motorola and offers first public stock, and into the 1950’s Motorola kept growing with new technological and commercial innovations in radio devices, television and personal pagers.
