2、开这些软件，就可以给 你的朋友发送信息，不管对方是否也同时在线，只要知道他有号码。linux操作系统作为一个开放资源的操作系统被越来越多的人所应用，它的 好处在于操作系统源代码的公开化！只要是基于gnu公约的软件你都可以任意 使用并修改它的源代码。但对很多习惯于windows操作系统的人来说，linux的 操作不够人性化、交互界而不够美观，这给linux操作系统的普及带来了很大的 阻碍。因此制作一个linux操作系统下的拥有人性化界面的实时通讯工具，将 给那些刚刚接触linux操作系统的用户带来极大的方便，而且通过设计这样的一 个应用程序还能更好的学习网络编程知识和掌握linux平台上应用程序

3、设计开 发的过程。编程语言和编程工具简介因为c语言是平台适应性最强的语言，差不多每种平台上都会有一个c编 译器。c语言也更易移植，因而，在linux下编程的最佳语言应该是c语言，linux 上的很多应用程序就是用c语言写的。因为gtk+和gnome是用c语言编写的, 所以在开发linux下的gui程序时使用c语言是非常方便的。linux发布版本中都提供了 c编译器gcc,它目前的版本是4. lolinux系统下的gcc （gnu c compiler）是gnu推出的功能强大、性能 优越的多平台编译器，是gnu的代表作品之一。gcc是可以在多种硬体平台上 编译岀可执行程序的超级编译器，其执行效率

4、与-般的编译器相比平均效率要高 20%30% gcc编译器能将c、c+语言源程序、汇程式化序和fi标程序编译、连 接成可执行文件，如果没有给出可执行文件的名字，gcc将生成一个名为a. out 的文件。调试器gdb能让你观察另一个程序在执行时的内部活动，或程序出错时发 生了什么。gdb主要能做四件事（包括为了完成这些事而附加的功能），帮助用 户找岀程序中的错误。运行程序，设置所有的能影响程序运行的东四。保证程序在指定的条件下停止。当程序停止时，让用户检查发生了什么。改变程序。那样用户可以试着修正某个bug引起的问题，然后继续查找另一 个 bugo用户可以用gdb来调试c和c+写的程序。该系统所

6、化参数，这将需要修改工作在新的 制度。另外，如果你的插件是用c / c接口（而不是vb的界面）创建，您将 需要使用对象来创建一个databloc对于像parsecommand功能结构参数。重塑你的脚木系统功能肓接可能需要较长时间，但会带来一些新的优势。主 要明显的是丰富的api相比，这是一个插件的可用的脚本系统提供。你的脚本 将可以做更多和更少的代码。您还可以利用界面窗口的messenger plus功能优势！ 为您的生活和脚本，完全融合在messenger创建窗口。不过，如果你想要直接加 载您的旧插件的dll,这里是如何做到这一点：/load a c plugin dllfunction l

10、e, it has the advantage of operating system open source code! as long as the convention is based on gnu software, you can free to use and modify its source code. but for many people who used to run windows operating systems, linux operating less humane, less attractive interface, which spread to the

20、features from scratch in the new messenger plus! live scripting system.if yoifre in a hurry, solution 1 may sound appealing ,so you may want to know that this solution comes with a couple of limitations. first, the scripting api does not give direct access to the old messenger com object (from the d

21、ays of windows messenger 4) which means that if your plugin was using the nimessengerobjn or nomessengern parameter of initialize, it will need to be modified to work in the new system. also, if your plugin was created with the c/c+ interface (as opposed to the vb interface), you will need to use a databloc object to create the structure parameters for functions like parsecommand.recreating your features directly in the scripting system may take longer but will bring several new advantages. the main obvious one is the rich api offered by the scripting system compared to the o
