Qt-Phonon

刚刚发现有一个很好用的工具在Eclipse：Project View --> properties --> Restore from Local History (可以将以前误删的文件找回)
以下是一个德国高手关于Phonon在WinXP的安装的介绍，是我至今看到最好的。阅读时请注意：这个是对于Qt对于Microsoft Visual Studio的，对于Qt和MinGW则无法进行操作，Qt的官方网站上已经有说道，我就是看介绍太不仔细，居然 没看到：Warning: The MinGW version of Qt does not support building the Qt backend. 所以，在这里我用的是MinGW + Qt openSource + Eclipse是无法building Qt backend 的.
以下我摘抄的要点,对于Microsoft Visual Studio的：
Compilation of Phonon under Windows XP

注意：Patch SDKs
Wired but true, the Windows SDK does not compile. It is somehow broken. You need to do the following:
Add the following line
#include "rpcsal.h"
to linenumber 32 in files
C:\Programme\Microsoft SDKs\Windows\v6.1\Include\medparam.h
C:\Programme\Microsoft SDKs\Windows\v6.1\Include\mediaobj.h .pro for qmake:
INCLUDEPATH = C:\DXSDK\Include \ C:\Program Files\Microsoft SDKs\Windows\v6.1\Include
LIBPATH += C:\Program Files\Microsoft SDKs\Windows\v6.1\Lib
产生: phonon.bat以及Configure"%PROGRAMFILES%\Microsoft DirectX SDK (April 2007)\utilities\bin\dx_setenv.cmd"
%PROGRAMFILES%\Microsoft SDKs\Windows\v6.1\Bin\SetEnv.Cmd
The last one should only be necessary if you use the Express Version, but it is no problem if is called anyway
注意：请使用Qt Command Prompt 然后进入Qt的目录执行configure.exe : If your environment is setup correctly, executing configure.exe on your Qt installation should automatically activate Phonon.
