automake工具集的使用

关于automake的重要性已经在上一篇文章中作了说明。上一篇‘大家’写的文章讲得十分详细，在这里鄙人还是要啰嗦一下，记下自己使用时的各种问题。

1，新建一个目录：auto，其中存放本项目所需的两个源文件：hello.c和hello.h，具体内容如下：

lihacker@lihacker-laptop:~/workspace/makefile/auto$ cat hello.c
#include "hello.h"
int main()
{
    printf("Hello everyone!\n");
}

 

lihacker@lihacker-laptop:~/workspace/makefile/auto$ cat hello.h
#include <stdio.h>

2，使用命令：autoscan

3，修改configure.scan文件如下：

lihacker@lihacker-laptop:~/workspace/makefile/auto$ cat configure.scan
# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.

AC_PREREQ([2.63])
AC_INIT(hello,1.0)
AM_INIT_AUTOMAKE(hello,1.0)
AC_CONFIG_SRCDIR([hello.h])
AC_CONFIG_HEADERS([config.h])

# 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])
AC_OUTPUT

4，保存退出，并cp configure.scan configure.in

5，运行aclocal

6，运行autoconf

7，运行autoheader

8，用VI编辑Makefile.am文件

lihacker@lihacker-laptop:~/workspace/makefile/auto$ vi Makefile.am
AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=hello
hello_SOURCES=hello.c hello.h

9，运行automake --add-missing(一定要加上后面这个参数，不然下一步没法做)

lihacker@lihacker-laptop:~/workspace/makefile/auto$ automake --add-missing
configure.in: installing `./install-sh'
configure.in: installing `./mkinstalldirs'
configure.in: installing `./missing'
Makefile.am: installing `./depcomp

10，运行./configure

lihacker@lihacker-laptop:~/workspace/makefile/auto$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking for style of include used by make... GNU
checking dependency style of gcc... gcc3
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: executing depfiles commands

11，运行make

lihacker@lihacker-laptop:~/workspace/makefile/auto$ make
cd . && /bin/bash /home/lihacker/workspace/makefile/auto/missing --run autoheader
rm -f stamp-h1
touch config.h.in
cd . && /bin/bash ./config.status config.h
config.status: creating config.h
config.status: config.h is unchanged
make all-am
make[1]: Entering directory `/home/lihacker/workspace/makefile/auto'
make[1]: Leaving directory `/home/lihacker/workspace/makefile/auto

12，运行./hello

lihacker@lihacker-laptop:~/workspace/makefile/auto$ ./hello
Hello
