  • Functional C
    Functional C Pieter Hartel Henk Muller January 3, 1999 i Functional C Pieter Hartel Henk Muller University of Southampton University of Bristol Revision: 6.7 ii To Marijke Pieter To my family and other sources of inspiration Henk Revision: 6.7 c 1995,1996 Pieter Hartel & Henk Muller, all rights reserved. Preface The Computer Science Departments of many universities teach a functional lan- guage as the first programming language. Using a functional language with its high level of abstraction helps to emphasize the principles of programming. Func- tional programming is only one of the paradigms with which a student should be acquainted. Imperative, Concurrent, Object-Oriented, and Logic programming are also important. Depending on the problem to be solved, one of the paradigms will be chosen as the most natural paradigm for that problem. This book is the course material to teach a second paradigm: imperative pro- gramming, using C as the programming language. The book has been written so that it builds on the knowledge that the students have acquired during their first course on functional programming, using SML. The prerequisite of this book is that the principles of programming are already understood; this book does not specifically aim to teach `problem solving' or `programming'. This book aims to: ¡ Familiarise the reader with imperative programming as another way of imple- menting programs. The aim is to preserve the programming style, that is, the programmer thinks functionally while implementing an imperative pro- gram. ¡ Provide understanding of the differences between functional and imperative pro- gramming. Functional programming is a high level activity.

  • Building the Package
    5 Building the package Nowwehav e configured our package and we’re ready to build. This is the Big Moment: at the end of the build process we should have a complete, functioning software product in our source tree. In this chapter,we’ll look at the surprises that make can have instore for you. Youcan find the corresponding theoretical material in Chapter 19, Make. Preparation If you’re unlucky, a port can go seriously wrong. The first time that error messages appear thick and fast and scroll offthe screen before you can read them, you could get the impression that the packages were built this way deliberately to annoyyou. Alittle bit of preparation can go a long way towards keeping you in control of what’sgoing on. Here are some suggestions: Makesure you have enough space One of the most frequent reasons of failure of a build is that the file system fills up. If possi- ble, ensure that you have enough space before you start. The trouble is, howmuch is enough? Hardly anypackage will tell you howmuch space you need, and if it does it will probably be wrong, since the size depends greatly on the platform. If you are short on space, consider compiling without debugging symbols (which takeupalot of space). If you do run out of space in the middle of a build, you might be able to save the day by stripping the objects with strip,inother words removing the symbols from the file. Use a windowing system The sheer size of a complicated port can be a problem.

  • Useful Things in the C Programming Environment
    Useful Things in the C Programming Environment Remzi Arpaci-Dusseau Introduction This is a very brief document to familiarize you with the basics of the C programming environment on UNIX-based systems. It is not comprehensive or detailed, but should just give you enough to get you going. A couple of general points of advice about programming: if you want to become an expert programmer, you need to master more than just the syntax of a language. Specifically, you should know your tools, know your libraries, and know your documentation. The tools that are relevant to C and C++ compilation are gcc, gdb, and maybe ld. There are tons of library routines that are also available to you, but fortunately a lot of functionality is included in libc, which is linked with all C and C++ programs by default – all you need to do is include the right header files. Finally, knowing how to find the library routines you need (e.g., learning to find and read man pages) is a skill worth acquiring. We’ll talk about each of these in more detail later on. Like (almost) everything worth doing in life, becoming an expert in these domains takes time, but the result of spending the time up-front will definitely be well worth the effort. A Simple C Program We’ll start with a simple C program, perhaps saved in the file “hw.c”. Unlike Java, there is no connection between the file name and the contents of the file; because of that, just use your common sense in naming files.

  • X Window System, Version 11, Release 4, Release
    X Window System, Version 11 Release 4 Release Notes Jim Fulton X Consortium MIT Laboratory for Computer Science ABSTRACT The X Window System is a portable, network-transparent window system origi- nally developed at MIT. It can be used on a wide variety of raster display devices, ranging from from simple monochrome frame buffers to deep, true color graphics pro- cessors. This document describes contents of the fourth public release of X, Version 11 from MIT and how it has changed from previous releases. 1. Overview This is the fourth release of the X Window System, Version 11 from MIT. Substantial progress has been made in optimizing the sample server, window manager, and programming libraries. In addition, major improvements to the user interface of several of the key applications (in particular, xmh, twm, xman, and xterm) should make release noticably nicer to use. Sample implementations of the various new Consortium Standards are included as well as prototype implementations of several efforts currently under development. No incompatible changes have been made to either the core Protocol or to the Xlib programming library. The Xt Intrinsics should be source compatible with the previous release. Changes have been made to the Xaw widget set, but a configuration option for providing back- wards compatibility interfaces is available. Several new sets of fonts have been added: a new fixed width family of fonts, a Kanji and Kana font, the Lucida family from Bigelow & Holmes and Sun Microsystems, a terminal emulator font from Digi- tal Equipment Corporation, and 100 dots-per-inch (dpi) versions of all 75dpi fonts.

  • Development Tools
    b544977 Ch09.qxd 12/1/03 8:56 AM Page 365 9 Development Tools In this chapter, we’ll look at some of the tools available for developing programs on Linux systems, some of which are also available for UNIX. In addition to the obvious necessities of compilers and debuggers, Linux provides a set of tools, each of which does a single job, and allows the developer to combine these tools in new and innovative ways. This is part of the UNIX philosophy Linux has inherited. Here, we’ll look at a few of the more important tools and see some examples of their being used to solve problems, including ❑ The make command and makefiles ❑ Source code control using RCS and CVS ❑ Writing a manual page ❑ Distributing software using patch and tar ❑ Development environments Problems of Multiple Source Files When they’re writing small programs, many people simply rebuild their application after edits by recompiling all the files. However, with larger programs, some problems with this simple approach become apparent. The time for the edit-compile-test cycle will grow. Even the most patient programmer will want to avoid recompiling all the files when only one file has been changed. A potentially much more difficult problem arises when multiple header files are created and included in different source files. Suppose we have header files a.h, b.h, and c.h, and C source files main.c, 2.c, and 3.c. (We hope that you choose better names than these for real projects!) We could have the situation following situation.

Build Process • The build process can often: – Be complex – Rely on several different processes – Be time-consuming – Be difficult to remember defs.h command.h main.m kbd.m main.o kbd.o edit Steps towards make • Complex => write a shell script and run that • But that’s time consuming (compiling a million lines used to take 24 hours) • So just recompile the bits that need recompiling and relink • Do that using ‘if’ in scripts. • But that’s tricky and repetitive. • Sounds like a task for a little language! • Also, we can derive more than one artefact from the same sources (code, several kinds of library, static checks, listings, archives, …) Make combines 3 languages • A scripting language (normally sh) for commands • A language for stating target(s)-depends-on- source(s) edges in a dependency graph • A templating language for constructing the others • Mixing several languages is always tricky; even if each one is simple, the combination may not be. Dependencies • If a header changes then the source must be recompiled – If command.h changes then • recompile kbd.m • relink edit • Actually, we must rebuild: – All files that include the header – All executables that depend on the object code – All libraries that depend on the object code – All executables that depend on the library – All web-listings, cross-references,
