Xvid编译的error C2520问题及解决

自www.xvid.org 下载源代码后，按照doc目录下的INSTALL安装之。编译时出现错误：

C:/Downloads/xvidcore-1.0.1/xvidcore-1.0.1/src/plugins/plugin_2pass2.c(444) : error C2520: conversion from unsigned __int64 to double not implemented, use signed __int64

最终解决方法：

1、安装Visual Studio 6 Service Pack 5

2、安装Visual C++ Processor Pack 5 (for VSSP5)

2只能在1上安装，而不能在VSSP6上安装

当然还有其它的解决方法：

自行修改xvid的代码或者用GCC for mingW，未曾尝试
