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 
    
         #include 
     
          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
