autoconf 简单demo试用

1. 安装工具

yum install  -y automake

 

2. 基本项目

a. 项目参考结构

├── AUTHORS
├── COPYING
├── ChangeLog
├── Makefile.am
├── NEWS
├── README
├── README.md
├── a.out
├── configure.ac
├── main
└── main.c

b.  configure.ac  Makefile.am  main.c

configure.ac  Makefile.am

configure.ac

AC_INIT([main],[0.0.1])
AC_CONFIG_SRCDIR("main.c")
AC_CONFIG_AUX_DIR([build-aux])
AM_INIT_AUTOMAKE([1.11 -Wall -Werror])
AC_CONFIG_FILES([Makefile])
AC_PROG_CC
AC_OUTPUT

Makefile.am

bin_PROGRAMS = main
main_SOURCES =main.c

main.c

#include <stdio.h>

int main (){

 printf("%s","appdemo");
 return 0;

}

c. 生成文档

autoreconf  -i  提示的错误信息如下：

Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './README' not found
Makefile.am: error: required file './ChangeLog' not found
Makefile.am: installing './COPYING' using GNU General Public License v3 file
Makefile.am:     Consider adding the COPYING file to the version control system
Makefile.am:     for your code, to avoid questions about which license your project uses
autoreconf: automake failed with exit status: 1

解决方法
list="INSTALL NEWS README AUTHORS ChangeLog COPYING"
touch  $list

重新生成之后  ./configure

d. make && install 

make install 

备注：或者使用autoscan 帮助生成部分代码，也是一个不错的选择
