I am now working on a project to tranlate a system form unix to VC. This code


can excute well in unix and I can also copile in VC, but when I run my program it give an error info says "access violation".

COMPRESSION_LZ /*5: Lempel-Ziv & Welch */

Can anybody give me some suggestion how to fix this problem.

When your code linked properly - as it seems - your problem is NOT missing LZW en/decoder code.

For a LZW license, the Unisys website is a good starting point (but I think Google and "Unisys LZW license" is as good). I have the URL somewhere, but not at hand ATM ;)
