Glib实例学习（0）开始

1：Glib概述

    Glib是一个底层库，她提供了一系列的的数据类型以及关于这些数据的操作，这些数据类型大概包括：

    Memory chunks
    Doubly-linked lists
    Singly-linked lists
    Hash tables
    Strings (which can grow dynamically)
    String chunks (groups of strings)
    Arrays (which can grow in size as elements are added)
    Balanced binary trees
    N-ary trees
    Quarks (a two-way association of a string and a unique integer identifier)
    Keyed data lists (lists of data elements accessible by a string or integer id)
    Relations and tuples (tables of data which can be indexed on any number of fields)
    Caches

2：从“Hello world”开始

#include <stdio.h>
    #include <glib.h>

    int
    main(int agrc, char **argv)
    {
        g_printf("Hello world!\n");

        return 0;
    }

    $ gcc -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -lglib-2.0 -o hello hello.c

    $ ./hello

鉴于手工指定库相关信息比较麻烦而且容易出错，大部分的发行版Linux 都提供了pkgconfig 工具：

$ gcc `pkg-config --cflags --libs glib-2.0` -o hello hello.c

    $ ./hello
