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
