• autoconf 添加三方库(libcurl)简单试用


    1. 参考项目

    https://github.com/rongfengliang/autoconf-project
    2. 项目说明
    a. 项目结构
    ├── Jenkinsfile  # jenkins 构建,实际使用可选
    ├── Makefile.am  
    ├── README.md
    ├── autogen.sh   # 生成配置的shell
    ├── configure.ac # configure 配置说明
    ├── src
    │   ├── Makefile.am # makefile 构建说明
    │   ├── main.c
    │   ├── userservice.c
    │   ├── userservice.h
    
    b. configure.ac 
    
    #                                               -*- Autoconf -*-
    # Process this file with autoconf to produce a configure script.
    
    AC_PREREQ([2.69])
    AC_INIT([dalongdemoapp], [0.0.1], [dalong@qq.com])
    AC_CONFIG_SRCDIR([src/main.c])
    AC_CONFIG_HEADERS([config.h])
    AM_INIT_AUTOMAKE
    
    # Checks for programs.
    AC_PROG_CXX
    AC_PROG_CC
    AC_PROG_INSTALL
    AC_PROG_AWK
    AC_PROG_MKDIR_P
    
    # Checks for libraries.
    AC_CHECK_LIB([curl])  # libcurl check
    
    # Checks for header files.
    AC_CHECK_HEADERS([string.h])
    
    # Checks for typedefs, structures, and compiler characteristics.
    
    # Checks for library functions.
    
    AC_CONFIG_FILES([Makefile
                     src/Makefile])
    AC_OUTPUT
    
    c. Makefile.am 
    
    AUTOMAKE_OPTIONS=foreign
    SUBDIRS=src
    
    d. src/Makefile.am
    
    bin_PROGRAMS=dalongdemoapp
    dalongdemoapp_SOURCES=main.c userservice.c
    include_HEADERS=userservice.h
    dalongdemoapp_LDADD=-lcurl 
    
    备注:dalongdemoapp_LDADD=-lcurl 获取方式
    可以使用pkg-confg   
    命令如下: 
    pkg-config --libs --cflags libcurl
    
    e. main.c userservice.c userservice.h
    
    主要是一个简单的demo 以及一个使用libcurl 获取博客园博客信息的
    主要方法userservice.h/printcontent
    3. 生成使用
    ./autogen.sh
    ./configure
    make
    src/dalongdemoapp
    
    备注: 实际系统需要安装libcurl 对于centos如下: 
    yum install -y libcurl-devel
