Qt Deployment on Windows

在 Windows 上 deploy Qt 程式也很簡單

只要把引用的相關 share library 放在程式的同一個目錄底下, 就完成了

Qt 引用的 library 有哪些呢？

有 1. Qt library 2. compiler specific library

compiler specific share library 就看你使用的 compiler 是哪一種, 就把對應的 library copy 到目錄底下

Qt	VC++ 6.0	VC++ 7.1 (2003)	VC++ 8.0 (2005)	MinGW
QTCORE4.DLL - The QtCoreruntime QTGUI4.DLL - The QtGuiruntime	MSVCRT.DLL - The C runtime MSVCP60.DLL - The C++ runtime (only when STL is installed)	MSVCR71.DLL - The C runtime MSVCP71.DLL - The C++ runtime (only when STL is installed)	MSVCR80.DLL - The C runtime MSVCP80.DLL - The C++ runtime (only when STL is installed)	MINGWM10.DLL - The MinGW run-time

那要怎樣才知道引用哪些 Qt library 呢？

可以用 Dependency Walker 來查詢

Qt deployment on Mac

在 Mac 上 deploy Qt 程式很簡單

只要使用 Qt SDK 所提供的 macdeployqt 指令就可以完成 deployment

macdeployqt 會將程式引用的相關 Qt library 打包, 並且改變引用路徑

以下以 MyApp.app 做為範例：

mac 提供一個 otool 指令可以查看程式引用的 share library

$ otool -L MyApp.app/Contents/MacOS/MyApp

MyApp.app/Contents/MacOS/MyApp:

/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 635.21.0)
/Users/OOO/QtSDK/Desktop/Qt/4.8.0/gcc/lib/QtWebKit.framework/Versions/4/QtWebKit (compatibility version 4.8.0, current version 4.8.0)
/Users/OOO/QtSDK/Desktop/Qt/4.8.0/gcc/lib/QtGui.framework/Versions/4/QtGui (compatibility version 4.8.0, current version 4.8.0)
/Users/OOO/QtSDK/Desktop/Qt/4.8.0/gcc/lib/QtNetwork.framework/Versions/4/QtNetwork (compatibility version 4.8.0, current version 4.8.0)
/Users/OOO/QtSDK/Desktop/Qt/4.8.0/gcc/lib/QtCore.framework/Versions/4/QtCore (compatibility version 4.8.0, current version 4.8.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1094.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

以上紅色的字就是 MyApp.app 引用的相關 Qt share library, 注意這裡是絕對路徑

使用 macdeployqt 指令, 來 deploy Qt 程式
macdeployqt 在 Qt SDK 安裝目錄底下可以找到, 要稍微找一下

$ macdeployqt MyApp.app

接下來再用一次 otool

$ otool -L MyApp.app/Contents/MacOS/MyApp
MyApp.app/Contents/MacOS/MyApp:

/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 635.21.0)
@executable_path/../Frameworks/QtWebKit.framework/Versions/4/QtWebKit (compatibility version 4.8.0, current version 4.8.0)
@executable_path/../Frameworks/QtGui.framework/Versions/4/QtGui (compatibility version 4.8.0, current version 4.8.0)
@executable_path/../Frameworks/QtNetwork.framework/Versions/4/QtNetwork (compatibility version 4.8.0, current version 4.8.0)
@executable_path/../Frameworks/QtCore.framework/Versions/4/QtCore (compatibility version 4.8.0, current version 4.8.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1094.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

有沒有發現, macdeployqt 指令已經將相關 Qt share library 打包, 並且將絕對路徑改成相對路徑

這樣有沒有很簡單?
