C语言用GNU源码编译建构系统工具（GNU BUILD SYSTEM）编译创建动态库
C语言用GNU源码编译建构系统工具（GNU BUILD SYSTEM）编译创建动态库
- 首先看一下这篇博文：C语言数据结构之顺序结构（Sequence）
- 此次目的是将sequence.c改造一下，创建为一个动态链接库同时打包一个可发布的源码包，包括源码、头文件、测试文件！
创建工作目录
- 工作目录libmg（mg即muggles，一定要有一个自己的名称空间namespace）
工作目录结构如下所示：
libmg
\- Makefile.am
\- src
\- Makefile.am
\- sequence.c
\- libmg.h
\- mg
\- Makefile.am
\- types.h
\- sequence.h
\- tests
\- Makefile.am
\- test_seq.c
每个子目录下都编辑一个Makefile.am文件！！！
- 主目录libmg/Makefile.am内容如下：
SUBDIRS = src tests
- 源码目录libmg/src/Makefile.am内容如下：
SUBDIRS = mg
lib_LTLIBRARIES = libmg.la
libmg_la_SOURCES = libmg.h \
mg/types.h \
sequence.c mg/sequence.h
libmg_la_LDFLAGS = -release 1.0
include_HEADERS = libmg.h
nobase_include_HEADERS = \
mg/types.h \
mg/sequence.h
- 源码目录下子目录mg的libmg/src/mg/Makefile.am内容如下：
EXTRA_DIST = types.h sequence.h
- 测试目录tests/Makefile.am内容如下：
AM_CFLAGS = -I ../src -I .
AM_LDFLAGS = -L../src -lmg
check_PROGRAMS = test_seq
test_seq_SOURCES = test_seq.c
TESTS = $(check_PROGRAMS)
将源码sequence.c改造一下
- 主头文件libmg/src/libmg.h代码如下：
/* filename : libmg.h */
#ifndef __LIBMG_HEAD
#define __LIBMG_HEAD
#include "mg/types.h"
#include "mg/sequence.h"
#endif/*__LIBMG_HEAD*/
- 主源码文件libmg/src/sequence.c代码如下：

#include <stdio.h>
#include <stdlib.h>
#include "mg/sequence.h"
/* create a new sequence */

- 注意libmg.h头文件，用到sequence相关函数的话，包含libmg.h即可！！！
运行autoscan命令，生成配置文件
- 运行 autoscan
- 更改文件名 mv configure.scan configure.ac
编辑配置文件configure.ac，修改以下四处
- 修改包名字、版本号、报错邮件地址 AC_INIT([libmg], [0.1], [gwsong52@qq.com])
- 添加AUTOMAKE宏 AM_INIT_AUTOMAKE([ -Wall -Werror foreign ])
- 添加检查ar工具宏 AM_PROG_AR
- 添加检查LIBTOOL宏 LT_INIT
修改后内容如下：
# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
AC_PREREQ([2.69])
AC_INIT([libmg], [0.1], [gwsong52@qq.com])
AM_INIT_AUTOMAKE([ -Wall -Werror foreign ])
AC_CONFIG_SRCDIR([tests/test_seq.c])
AC_CONFIG_HEADERS([config.h])
# Checks for programs.
AM_PROG_AR
AC_PROG_CC
#
LT_INIT
# Checks for libraries.
# FIXME: Replace `main' with a function in `-lmg':
# AC_CHECK_LIB([mg], [main])
# Checks for header files.
AC_CHECK_HEADERS([stdlib.h])
# Checks for typedefs, structures, and compiler characteristics.
# Checks for library functions.
AC_FUNC_MALLOC
AC_FUNC_REALLOC
AC_CONFIG_FILES([Makefile
src/Makefile
src/mg/Makefile
tests/Makefile])
AC_OUTPUT
运行命令：autoreconf --install 生成 configure 脚本
如下所示：
songvm@ubuntu:~/works/xdn/aoo/libmg$ ls
autoscan.log configure.ac Makefile.am src tests
songvm@ubuntu:~/works/xdn/aoo/libmg$ autoreconf --install
libtoolize: putting auxiliary files in '.'.
libtoolize: copying file './ltmain.sh'
libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,

libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

songvm@ubuntu:~/works/xdn/aoo/libmg$
运行 configure 脚本，生成 Makefile
- 运行命令：./configure --prefix=/tmp/boo ，注意加参数！！！
如下所示：
songvm@ubuntu:~/works/xdn/aoo/libmg$ ls
aclocal.m4 compile configure ltmain.sh src
ar-lib config.guess configure.ac Makefile.am test-driver
autom4te.cache config.h.in depcomp Makefile.in tests

----------------------------------------------------------------------
Libraries have been installed in:
/tmp/boo/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
