使用autotool工具自动生成 Makefile

1、准备
    $ cd /tmp
    $ mkdir hello
    $ mkdir src
    $ cd src
    $ vim hello.c
        #include <stdio.h>

        int main(int argc, char *argv[])
        {
            printf("Hello, World!\n");

            return 0;
        }

    $ vim Makefile.am
        AUTOMAKE_OPTIONS=foreign
        AM_CFLAGS =\
                   -Wall\
                   -g

        bin_PROGRAMS = hello
        hello_SOURCES = hello.c

    $ cd /tmp/hello
    $ vim Makefile.am
        AUTOMAKE_OPTIONS=foreign
        SUBDIRS=src

2、autoscan
    $ autoscan
    $ mv configure.scan configure.in
    modify configure.in
        #                                               -*- Autoconf -*-
        # Process this file with autoconf to produce a configure script.

        AC_PREREQ([2.67])
        AC_INIT([hello], [1.0], [[email protected]])
        AC_CONFIG_SRCDIR([src/hello.c])
        AC_CONFIG_HEADERS([config.h])
        AM_INIT_AUTOMAKE(hello, 1.0)

        # Checks for programs.
        AC_PROG_CC

        # Checks for libraries.

        # Checks for header files.

        # Checks for typedefs, structures, and compiler characteristics.

        # Checks for library functions.

        AC_CONFIG_FILES([Makefile
                        src/Makefile])
        AC_OUTPUT

3、aclocal
    $ aclocal

4、autoconf
    $ autoconf

5、autoheader
    $ autoheader

6、automake
    $ automake --add-missing

7、./configure
    $ ./configure

8、make
    $ make

9、run
    $ ./src/hello
