2、開這些軟件，就可以給 你的朋友發(fā)送信息，不管對(duì)方是否也同時(shí)在線，只要知道他有號(hào)碼。linux操作系統(tǒng)作為一個(gè)開放資源的操作系統(tǒng)被越來越多的人所應(yīng)用，它的 好處在于操作系統(tǒng)源代碼的公開化！只要是基于gnu公約的軟件你都可以任意 使用并修改它的源代碼。但對(duì)很多習(xí)慣于windows操作系統(tǒng)的人來說，linux的 操作不夠人性化、交互界而不夠美觀，這給linux操作系統(tǒng)的普及帶來了很大的 阻礙。因此制作一個(gè)linux操作系統(tǒng)下的擁有人性化界面的實(shí)時(shí)通訊工具，將 給那些剛剛接觸linux操作系統(tǒng)的用戶帶來極大的方便，而且通過設(shè)計(jì)這樣的一 個(gè)應(yīng)用程序還能更好的學(xué)習(xí)網(wǎng)絡(luò)編程知識(shí)和掌握linux平臺(tái)上應(yīng)用程序

3、設(shè)計(jì)開 發(fā)的過程。編程語言和編程工具簡介因?yàn)閏語言是平臺(tái)適應(yīng)性最強(qiáng)的語言，差不多每種平臺(tái)上都會(huì)有一個(gè)c編 譯器。c語言也更易移植，因而，在linux下編程的最佳語言應(yīng)該是c語言，linux 上的很多應(yīng)用程序就是用c語言寫的。因?yàn)間tk+和gnome是用c語言編寫的, 所以在開發(fā)linux下的gui程序時(shí)使用c語言是非常方便的。linux發(fā)布版本中都提供了 c編譯器gcc,它目前的版本是4. lolinux系統(tǒng)下的gcc （gnu c compiler）是gnu推出的功能強(qiáng)大、性能 優(yōu)越的多平臺(tái)編譯器，是gnu的代表作品之一。gcc是可以在多種硬體平臺(tái)上 編譯岀可執(zhí)行程序的超級(jí)編譯器，其執(zhí)行效率

4、與-般的編譯器相比平均效率要高 20%30% gcc編譯器能將c、c+語言源程序、匯程式化序和fi標(biāo)程序編譯、連 接成可執(zhí)行文件，如果沒有給出可執(zhí)行文件的名字，gcc將生成一個(gè)名為a. out 的文件。調(diào)試器gdb能讓你觀察另一個(gè)程序在執(zhí)行時(shí)的內(nèi)部活動(dòng)，或程序出錯(cuò)時(shí)發(fā) 生了什么。gdb主要能做四件事（包括為了完成這些事而附加的功能），幫助用 戶找岀程序中的錯(cuò)誤。運(yùn)行程序，設(shè)置所有的能影響程序運(yùn)行的東四。保證程序在指定的條件下停止。當(dāng)程序停止時(shí)，讓用戶檢查發(fā)生了什么。改變程序。那樣用戶可以試著修正某個(gè)bug引起的問題，然后繼續(xù)查找另一 個(gè) bugo用戶可以用gdb來調(diào)試c和c+寫的程序。該系統(tǒng)所

6、化參數(shù)，這將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）創(chuàng)建，您將 需要使用對(duì)象來創(chuàng)建一個(gè)databloc對(duì)于像parsecommand功能結(jié)構(gòu)參數(shù)。重塑你的腳木系統(tǒng)功能肓接可能需要較長時(shí)間，但會(huì)帶來一些新的優(yōu)勢(shì)。主 要明顯的是豐富的api相比，這是一個(gè)插件的可用的腳本系統(tǒng)提供。你的腳本 將可以做更多和更少的代碼。您還可以利用界面窗口的messenger plus功能優(yōu)勢(shì)！ 為您的生活和腳本，完全融合在messenger創(chuàng)建窗口。不過，如果你想要直接加 載您的舊插件的dll,這里是如何做到這一點(diǎn)：/load a c plugin dllfunction l

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
