请教关于fatal error LNK1104: 无法打开文件“libcimt.lib”解决方法
大家好，最近由于工作需要，找到了一个ppmd压缩，解压算法，算法是用VC6.0开发的，但是转换成VS2005的项目后，总是报错fatal error LNK1104: 无法打开文件“libcimt.lib”。我已将VC6下的ppmd_coder.h 中#include <iostream.h>、#include <fstream.h>改成了#include <iostream>、#include <fstream>，并使用了using namespace std命令。感觉问题出在fstream，但耐与能力有限，找不出问题的真正所在，烦请各位大侠给予指点帮助。ppmd算法的下载地址：http://hi.baidu.com/%B4%F3%D5%AC%C0%C7/blog/item/68fb6f55df0164133b293516.html
现将ppmd_coder.h附上，希望各位大侠给提供个解决思路，谢谢。

/** PPMD_Coder is a class to compress and uncompress a file using the very
sophisticated PPMD method. It is based on the public domain code by Dmitry
Shkarin which is widely available. Please notice that only one file can
compressed, archiving several files can be done with the help of TAR.
There is no general rule which OrderSize to use. If you have highly repeatable
data it's worth to use a high value but in general this should be avoided
because the overhead is slightly greater and would increase your output file
compared to smaller OrderSizes. Just play around with the values to see what
I mean.
The SubAllocatorSize is the size in MB which will be allocated dynamically
on the heap. Only use high values if you have enough memory.
You must include the "ppmd.lib" in your project!
Please send any bugs to:

希望大侠们给提个思路，我调试的时候只要包含 fstream.h就会报这个链接错误，貌似以下这个网址能给些帮助http://msdn.microsoft.com/zh-cn/library/8h8eh904(VS.90).aspx
