I wound up using the ZLIB library (see www.zlib.org <http://www.zlib.org> ), with small C and CL wrapper files to access the zip and unzip functionality through FFI. I have this working on Linux (CMU) and Windows (ACL), with not a huge amount of effort. Look in the contrib/minizip directory. -----Original Message----- From: Bill Davis [mailto:[email protected]] Sent: Thursday, September 04, 2003 12:08 PM To: '[email protected]' Subject: ideas on "reversing" the process for deflate code? JKF's code to "inflate" a compressed stream is at http://opensource.franz.com/deflate/index.html <http://opensource.franz.com/deflate/index.html> As John's notes indicate that: We have written the code to uncompress deflated files, which we call Inflation. The source is available on our open source web site at http://opensource.franz.com/deflate/index.html <http://opensource.franz.com/deflate/index.html> . We will be adding code to show how to turn a simple-stream into a stream that inflates its input. At this point in time we have no plans to implement compression of files using the deflate algorithm. My question: Can anyone offer pointers or helpful insight on how one might be able to use the above-reference code to reverse the process and perform the original compression? We ultimately want to come through a list of specific files and generate a compressed file (as if we had manually does it with a "WinZip" utility). Thanks in advance.
