在把这个
玩玩DirectShow--(1)Sample: Texture3D9 改成Unicode版本的时候，总是链接不过，居然好长时间都没想到是链接的strmbasd.lib不是unicode的，我靠！憋着没问别人，终于解决了。培养独立解决问题的能力！
在目录C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Samples\Multimedia\DirectShow\BaseClasses\里
自己建个新文件叫makefile_unicode，把makefile的内容拷过来，改几个地方
1）粗体的部分加了个u
!IFDEF NODEBUG
STRMBASE=strmbaseu
!else
STRMBASE=strmbasud
!endif
2） 编译选项增加了
/D "_UNICODE" /D "UNICODE"看下面的粗体部分就是改变的部分

好了，开始生成吧
