• 使用bakefile编译C工程代码


    一、前言

    最近有个想法,想把 ineedle 整体架构从头自己编写代码来实现一下,来加深对iNeedle系统的理解,同时加强Linux + C相关知识。由于iNeedle系统的庞大,只能是先把框架搭起来,根据某些功能再往里边添加东西。首先遇到的问题就是每写一部分代码都要进行调试,既不想使用gcc独立的命令来进行调试,这样代码多了或路径复杂就难以控制;又不想使用iNeedle原版的编译文件,于是自己按照旧版本抽取出需要编译iNeedle系统的脚本代码来。这个脚本用来编译iNeedle项目,主要是利用了bakefile工具。bakefile是一个跨平台的自动生成makefile的开源工具,需要在项目中的每个子目录中指定***.bkl配置文件(该配置文件指定需要编译哪些文件,指定头文件等),bakefile利用每个子目录中bkl文件来生成相应的makefile文件;然后在主目录(编译文件所在目录)中生成主makefile文件,由主makefile直接进行系统编译,生成可执行程序。

    1、如果CentOS系统安装:

    yum install bakefile -y

    2、如果debian或ubuntu系统:
    需要源码安装,可以到官网下载bakefile-0.2.9.tar.gz版本的即可:

    tar -zxvf bakefile-0.2.9.tar.gz; 
    cd bakefile-0.2.9; 
    ./configure; 
    make; 
    make install

    二、bakefile使用

    bakefile -f gnu "$folder.bkl" -o "$folder.mk" >/dev/null 2>&1

    单独使用使用make命令进行编译:

    make -f ineedle.mk install

    三、bkl文件参考

     1 <?xml version="1.0"?>
     2 <makefile>
     3     <template id="posT">
     4         <include>../include/pcap</include>
     5         <include>../include/</include>
     6         <include>./</include>
     7         <sources>pos/pos_lib.c</sources>
     8         <sources>pos/pos_var.c</sources>
     9         <sources>pos/db_var.c</sources>
    10         <sources>pos/pos_db.c</sources>
    11         <sources>pos/hk.c</sources>
    12         <sources>pos/hashfunctions.c</sources>
    13         <sources>pos/md5.c</sources>
    14         <sources>pos/ios_time.c</sources>
    15         <sources>pos/pos_ut.c</sources>
    16         <sources>pos/ios_sparse.c</sources>
    17         <sources>pos/pos_lock.c</sources>
    18         <sources>pos/iweb_api.c</sources>
    19         <sources>pos/db_clean.c</sources>
    20         <sources>pos/pos_mem.c</sources>
    21     </template>
    22     <exe id="pos_obj" template="posT"></exe>
    23 </makefile>

    四、iNeedle系统编译脚本

    #!/bin/bash
    #
    #    这个编译文件是从老版本compile.dat中提取出来单独编译ineedle的,目的是用来调试ineedle使用的。
    #
