Can't get Large file and ZIP64 support with Zip 3.0 to work...

Hi folks,
I tried getting Large file and ZIP64 support with Zip 3.0 to work.

I build Zip 3.0 with the param LARGE, and under VMS ZIP64 support is implied with LARGE file support (see osdep.h).

SYSMGR> zip30 :== $DSA2:[ZIP30.ALPHAL]ZIP.EXE
SYSMGR> zip30 -v
Copyright (c) 1990-2008 Info-ZIP - Type 'zip "-L"' for software license.
This is Zip 3.0 (July 5th 2008), by Info-ZIP.
Currently maintained by E. Gordon. Please send bug reports to
the authors using the web page at www.info-zip.org; see README for details.

Latest sources and executables are at ftp://ftp.info-zip.org/pub/infozip,
as of above date; see http://www.info-zip.org/ for other sites.

Compiled with DEC C V7.1-015 for OpenVMS (V7.3-2 Alpha) on May 25 2009.

Zip special compilation options:
USE_EF_UT_TIME (store Universal Time)
VMS_PK_EXTRA
SYMLINK_SUPPORT (symbolic links supported, if C RTL permits)
LARGE_FILE_SUPPORT (can read and write large files on file system)
ZIP64_SUPPORT (use Zip64 to store large files in archives)

I keep getting errors like

End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.

Anyone got a clue?

Which UNZIP version ?
use "unzip -v" to show show if it supports large file.

From _UnZip_?

UnZip 6.0 has, at long last, been released.

Good advice. Info about the program which
emits the complaint can be useful.

I was using an old unzip... I downloaded Unzip 6.00 and now a job is running using both Zip 3.0 and Unzip 6.00. I had to leave the office so I can tell the result tomorrow. I think we hit the right button though.

I was not aware that Zip and Unzip versions are in fact tightly coupled.

In general, they're not, but if you use some
exotic, new feature, like large-file
support, in one, then it probably needs to be
in the other one, too. The story would be
similar for bzip2 compression, symbolic
links, or other new and exciting stuff.

The problem is solved!
With Zip 3.0 and Unzip 6.0 (released May 1st 2009) large file support works for me.

Thanks a lot for your hints!
