  • Download Chapter 3: "Configuring Your Project with Autoconf"
    CONFIGURING YOUR PROJECT WITH AUTOCONF Come my friends, ’Tis not too late to seek a newer world. —Alfred, Lord Tennyson, “Ulysses” Because Automake and Libtool are essen- tially add-on components to the original Autoconf framework, it’s useful to spend some time focusing on using Autoconf without Automake and Libtool. This will provide a fair amount of insight into how Autoconf operates by exposing aspects of the tool that are often hidden by Automake. Before Automake came along, Autoconf was used alone. In fact, many legacy open source projects never made the transition from Autoconf to the full GNU Autotools suite. As a result, it’s not unusual to find a file called configure.in (the original Autoconf naming convention) as well as handwritten Makefile.in templates in older open source projects. In this chapter, I’ll show you how to add an Autoconf build system to an existing project. I’ll spend most of this chapter talking about the fundamental features of Autoconf, and in Chapter 4, I’ll go into much more detail about how some of the more complex Autoconf macros work and how to properly use them. Throughout this process, we’ll continue using the Jupiter project as our example. Autotools © 2010 by John Calcote Autoconf Configuration Scripts The input to the autoconf program is shell script sprinkled with macro calls. The input stream must also include the definitions of all referenced macros—both those that Autoconf provides and those that you write yourself. The macro language used in Autoconf is called M4. (The name means M, plus 4 more letters, or the word Macro.1) The m4 utility is a general-purpose macro language processor originally written by Brian Kernighan and Dennis Ritchie in 1977.

  • Building Multi-File Programs with the Make Tool
    Princeton University Computer Science 217: Introduction to Programming Systems Agenda Motivation for Make Building Multi-File Programs Make Fundamentals with the make Tool Non-File Targets Macros Implicit Rules 1 2 Multi-File Programs Motivation for Make (Part 1) intmath.h (interface) Building testintmath, approach 1: testintmath.c (client) #ifndef INTMATH_INCLUDED • Use one gcc217 command to #define INTMATH_INCLUDED #include "intmath.h" int gcd(int i, int j); #include <stdio.h> preprocess, compile, assemble, and link int lcm(int i, int j); #endif int main(void) { int i; intmath.c (implementation) int j; printf("Enter the first integer:\n"); #include "intmath.h" scanf("%d", &i); testintmath.c intmath.h intmath.c printf("Enter the second integer:\n"); int gcd(int i, int j) scanf("%d", &j); { int temp; printf("Greatest common divisor: %d.\n", while (j != 0) gcd(i, j)); { temp = i % j; printf("Least common multiple: %d.\n", gcc217 testintmath.c intmath.c –o testintmath i = j; lcm(i, j); j = temp; return 0; } } return i; } Note: intmath.h is int lcm(int i, int j) #included into intmath.c { return (i / gcd(i, j)) * j; testintmath } and testintmath.c 3 4 Motivation for Make (Part 2) Partial Builds Building testintmath, approach 2: Approach 2 allows for partial builds • Preprocess, compile, assemble to produce .o files • Example: Change intmath.c • Link to produce executable binary file • Must rebuild intmath.o and testintmath • Need not rebuild testintmath.o!!! Recall: -c option tells gcc217 to omit link changed testintmath.c intmath.h intmath.c
