1、准备:
需要工具autoscan aclocal autoheader automake autoconf make 等工具.
2、测试程序编写:
建立目录:mkdir include src
编写程序:include/str.h
#include <stdio.h>
int str(char *string);
编写程序:src/str.c
#include "str.h"
//print string
int str(char *string){
printf("\n----PRINT STRING----\n\"%s\"\n",string);
return 0;
}
//interface of this program
int main(int argc , char **argv){
char str_read[1024];
printf("Please INPUT something end by [ENTER]\n");
scanf("%s",str_read);
return str(str_read );
}
3、生成configure.ac
configure.ac是automake的输入文件,所以必须先生成该文件。
执行命令:
[root@localhost str]# ls
include src
[root@localhost str]# autoscan
autom4te: configure.ac: no such file or directory
autoscan: /usr/bin/autom4te failed with exit status: 1
[root@localhost str]# ls
autoscan.log configure.scan include src
[root@localhost str]# cp configure.scan configure.ac
修改 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([include/str.h])
AC_CONFIG_HEADER([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_OUTPUT
修改
AC_INIT(FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS)
为
AC_INIT(str,0.0.1, [bug@sounos.org])
FULL-PACKAGE-NAME 为程序名称,VERSION为当前版本, BUG-REPORT-ADDRESS为bug汇报地址
添加AM_INIT_AUTOMAKE
添加AC_CONFIG_FILES([Makefile])
# -*- 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_INIT(str, 0.0.1, [bug@sounos.org])
AM_INIT_AUTOMAKE
AC_CONFIG_SRCDIR([include/str.h])
AC_CONFIG_HEADER([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、执行aclocal
[root@localhost str]# aclocal
/usr/share/aclocal/libfame.m4:6: warning: underquoted definition of AM_PATH_LIBFAME
run info '(automake)Extending aclocal'
