Writing makefile by hand is a very interesting thing, and for a relatively large project, if there is a tool to do it, it is a good thing. In the Linux system development environment, the GNU Autotools has undoubtedly played an important role. (in the development environment of Windows systems, IDE tools, such as visual Studio, are also handy for managing projects.) )

This article takes a simple project as an example to describe the use of a list of the GNU Autotools Tools and their commands.

Autotools is a series of tools, consisting mainly of autoconf, Automake, Perl locales, and M4, and contains five commands:
(1) aclocal
(2) AutoScan
(3) autoconf
(4) Autoheader
(5) Automake

first, prepare source code

(1) Directory project contains a main.c file and two subdirectory lib with a test.h in the Include;lib directory containing a test.c,include directory. In the system, it appears as follows:

[C-sharp] view plain copy [root@localhost project]# ls include lib main.c [root@localhost project]# [Roo T@localhost project]# ls include/test.h [root@localhost project]# ls lib/test.c [root@localhost project]#

(2) The source code is as follows:

[CPP] view plain Copy/* project/main.c/#include <stdio.h> #include "include/test.h" int main ()       {printf ("main entrance./n");       Test_method ();   return 0; }

[C-sharp] View plain Copy/* project/lib/test.c/#include <stdio.h> #include ".   /include/test.h "void Test_method () {printf (" Test method./n "); }

[CPP] view plain copy/* project/include/test.h*/void Test_method ();

second, the use of autotools steps

2.1 Using the AutoScan command, it scans the working directory and generates Configure.scan files.    [C-sharp] view plain copy [root@localhost project]# autoscan autom4te:configure.ac:no such file or directory AutoScan:/usr/bin/autom4te failed with exit status:1 [root@localhost project]# ls autoscan.log configure.scan i Nclude Lib Main.c [root@localhost project]#

2.2 Rename the Configure.scan file to Configure.ac and make the appropriate modifications. In Configure.ac, the line at the beginning of the # number is a comment, and the other is M4 macro command; The main function of the macros in Configure.ac is to detect the system.

[C-sharp]  View plain Copy [root@localhost project]mv configure.scan configure.ac   [ root@localhost project]# ls   autoscan.log  configure.ac include   lib  main.c   [root@localhost project]#   [root@localhost project]#  cat configure.ac   #                                                 -* - autoconf -*-   # process this file with autoconf to  produce a configure script.   ac_prereq (2.59)    Ac_init (Full-package-name,  version, bug-report-address)    Ac_config_srcdir ([main.c])    Ac_config_header ([ Config.h])    # Checks for programs.   ac_prog_cc
