NEW - plzip - a massively parallel OPEN-SOURCE-compressor based on LZMA

[joerg]

anyone knows this new plzip - program ?

but i can not find a windows 32 binary ...

Plzip uses the lzip file format;
the files produced by plzip are fully compatible with lzip-1.4 or newer.

http://www.nongnu.org/lzip/lzip.html

Plzip is intended for faster compression/decompression of big files on multiprocessor machines, which makes it specially well suited for distribution of big software files and large scale data archiving. On files big enough, plzip can use hundreds of processors.

it seems interesting ...

can someone here please build a win32 binary ?

There's a Win32 binary available for version 1.8 (link).

I also tried to compile 1.10-rc2 using G++ 3.4.5 with this command line:

g++ -O2 -Os -s -DPROGVERSION=\"1.10-rc2\" decoder.cc encoder.cc lziprecover.cc arg_parser.cc main.cc

It almost works, but some errors appear (f.e. S_IRGRP, fchmod, fchown). Guess these can be fixed either by changing some of the code or using a newer/other compiler.

@schnaader: thank you very much for your post

(http://mirrors.zerg.biz/nongnu/lzip/....8-win32-1.zip)

but it seems to be lzip ..

i am searching for a binary of plzip = "parallel-lzip"

maybe with using of "pthreadGC2.dll" ?

Ah, I see, my fault. There are no binaries for plzip, just one for lzip. I'll try building plzip later.

Sorry for the late reply, but I just checked my e-mails of the last month and saw that I missed one from Michael Ortmann who sent a win32 binary of plzip 0.5 (based on lzip 0.9). It includes the binary, pthreadGC2.dll and two source code diffs.

So, thanks Michael! Joerg, I hope this helps

there is a new version 0.8 (18-JAN-2012):

a windows - binary does not exist for now

@schaader:

thanks for publishing the windows-binary of version 0.5
would it be possible to do an update of the windows-binary to version 0.8 ?

best regards

Plzip is a massively parallel (multi-threaded), lossless data compressor
based on the lzlib compression library, with very safe integrity
checking and a user interface similar to the one of bzip2, gzip or lzip.
Plzip uses the lzip file format; the files produced by plzip are fully
compatible with lzip-1.4 or newer, and can be rescued with lziprecover.

Plzip is intended for faster compression/decompression of big files
on multiprocessor machines, which makes it specially well suited for
distribution of big software files and large scale data archiving. On
files big enough, plzip can use hundreds of processors.

I tried to apply the diffs from Michael (see my post above) to version 0.8 and compiling it together with the newest lzlib (1.3) - but though the compiler errors go away it gives a ton of linker errors and I don't know how to fix them. Perhaps some of the others can have a look at it and try to compile it.
