一、調(diào)試與發(fā)布

1、發(fā)布應(yīng)用程序時(shí)的候選者

（1）、調(diào)試版（debug）：開發(fā)階段生成可執(zhí)行程序

（2）、發(fā)布版（release）：最終產(chǎn)品的可執(zhí)行程序

2、調(diào)試版的可執(zhí)行程序

（1）、包含調(diào)試相關(guān)的信息，體積巨大

（2）、執(zhí)行速度慢，支持?jǐn)帱c(diǎn)調(diào)試

3、發(fā)布版的可執(zhí)行程序

（1）、無任何冗余信息，體積小巧

（2）、執(zhí)行速度快，無法映射到源碼調(diào)試

二、程序的庫(kù)依賴

1、可執(zhí)行程序的正常運(yùn)行需要外部庫(kù)的支持

因此：發(fā)布程序時(shí)必須保證所有依賴庫(kù)都存在

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

2、Windows可以用Depends工具查看程序的依賴庫(kù)

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

3、Linux可以用ldd命令查看程序的依賴庫(kù)

（1）、ldd是Linux系統(tǒng)中的一個(gè)腳本程序

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

三、程序的環(huán)境依賴

1、應(yīng)用程序?qū)τ趫?zhí)行程序環(huán)境可能還存在依賴關(guān)系

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

2、在客戶機(jī)上部署程序的執(zhí)行環(huán)境

（1）、方案一

A、用戶根據(jù)提供的手冊(cè)自行部署環(huán)境（不可?。?/span>

（2）、方案二

A、開發(fā)一個(gè)專用的部署（安裝）程序
B、部署（安裝）程序運(yùn)行后自動(dòng)部署執(zhí)行環(huán)境

3、部署（安裝）程序的開發(fā)

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

4、InstallShield的簡(jiǎn)介

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

5、Inno Setup簡(jiǎn)介

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

6、NSIS簡(jiǎn)介

Qt開發(fā)-應(yīng)用程序的打包與發(fā)布（qt程序打包發(fā)布安裝）

7、LinuxQt程序發(fā)布簡(jiǎn)介

（1）、方法一：

A、通過ldd命令確定程序的庫(kù)依賴

B、通過shell腳本開發(fā)部署程序

（2）、方法二

根據(jù)具體發(fā)行版開發(fā)專用部署程序（dep、rpm）

四、文本編輯器項(xiàng)目完整程序
