  • 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.

  • Analysis of Dynamics in Mobile Ad-Hoc Networks
    Analysis of Dynamics in Mobile Ad-Hoc Networks Student Project Student: JÄorgWagner Advisors: Vincent Lenders, Martin May Professor: Bernhard Plattner 31. July 2005 Task Formulation Summary Small and mobile devices such as handhelds (PDAs) with wireless communication capabilities (e.g. WLAN) are becoming more and more ubiquitous. Nowadays, the use of WLAN with such devices is mostly limited to downloading messages or sur¯ng the Web via a ¯xed access point. Ad hoc networking is a promising communication paradigm where devices form a network in a dynamic and self-organizing manner without any ¯xed infrastructure support such as access points or dedicated routers. Therefore, communication is no more limited to ¯xed places con- trolled by network operators but becomes in principle possible anywhere as long as cooperative nodes are available in the neighborhood. In order to develop protocols for ad hoc networks, researchers have made a set of assumptions on the user mobility. However, very few people have validated these assumptions with real networks. The goal of this thesis is to empirically analyze the mobility behavior of users and the resulting network characteristics. For this purpose, the student should collect data from a testbed consisting of approximately 20 handhelds carried by mobile users . The ¯rst task of the student is to develop the required tools and programs to monitor the desired network characteristics. Then, the student should distribute the hand- helds to test users (e.g. TIK members) and conduct the relevant measurements. When enough data is collected, the student should analyze the collected data and extract characteristics on relevant network metrics.
