Zipping 3+ Gb file in Solaris environment
underh20.s...@gmail.com
Does anyone know where I can download a Zip 64-bit utility in
Solaris OS, e.g., 8 or 10 ?
I need to zip a 3+ gb size file. We could not use "gzip" or
"compress" utility. The current zip program at our server cannot zip
any file over 2gb in size.
Thanks,
Bill

You can split the file and zip it.
So the size of the file will get reduced ( below 2GB )

Try something like:
cat file | gzip > file.gz
Doing the compression from standard input to standard output bypasses
the large file offset problems that you seem to be encountering.

The manual page for zip indicates that you can use it similarly for
single files
zip < bigfile > bigfile.zip
Also the .gz above should be a valid zip-file with a single member.

Actually I had a similar problem squeezing a VMWare Solaris 10 u4
"appliance"
I made which was 5GB in size. zip gzip etc all failed. I wanted to put
the lot
on a DVD so's to turn on a pal to Solaris. But zip wouldnt compress
the file.
So, I compiled a 64 bit version of zip but neither WinBlow$ or /usr/
bin/unzip could unpack it : /
bzip2 works fine unpacking in both universes though. Took the DVD over
and
used winrar (free demo) to unpack and now he's got Solaris 10 running.

Bill,
It's not it's 64 bitness that allows you to work on 2+ gig files per
se (although it helps). The binary (32 big executables) needs to be
largefile aware. According to the largefile man page the compress
utility is largefile aware (although it give lousy compression vs.
gzip or bzip2) in Solaris 9 and gzip is in Solaris 10.

Not quite. gzip does not generate zip files, although it can
_decompress_ a single-member (deflated) zip file.

If you are able to build from source then make the latest BETA version
of zip:
http://sourceforge.net/projects/infozip/
This will build large .zip files which include +2GB files and they
extract OK with WinZip on MS Windows.
The beta zip seems to work.
I had problems with the beta unzip utility on solaris (sparc) where it
will not read a .zip archive > 2GB. Not had time to debug code yet or
look at the issue (possibly I did not build it right, need to recheck,
but it was very easy).

I got unzip working, seems to be a problem with type definitions for
64-bit unsigned integer. Running with sun CC and an ugly hack to
unzip60c/unzpriv.h
*** 1753,1759 ****
# ifdef __GNUC__
typedef unsigned long long z_uint8;
# else
! typedef unsigned __int64 z_uint8;
# endif
# define Z_UINT8_DEFINED
# endif
--- 1753,1760 ----
# ifdef __GNUC__
typedef unsigned long long z_uint8;
# else
! typedef unsigned long long z_uint8;
! /* typedef unsigned __int64 z_uint8;*/
# endif
# define Z_UINT8_DEFINED
# endif
And then build using "make -f unix/Makefile generic". This needs a more
elegant solution but has me up and running with +2GB files.
