Bug 76627 – New ebuild: app-arch/lzma-0.02

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Mihai Limbasan 2005-01-04 05:46:22 UTC]

As requested in http://forums.gentoo.org/viewtopic.php?t=274644
Blurb: lzma is a high-performance data compressor based on the LZMA algorithm.
Its raison d'etre is that p7zip doesn't work as a pipe filter.
I had to patch the source to be able to compile it with GCC 3.4.x. It seems to work now, passed some impromptu tests of mine fine (tested on 32-bit x86 platform only though, ebuild keywords reflect that).
Also had to patch the makefile for it to pick up Gentoo's {C,CXX,LD}FLAGS.
Both patches attached. They are created by me, and in case it's an issue I assign copyright for them to whoever / whatever / I frankly don't care ;-)

Reproducible: Always

[Comment 5 Martin Ankerl 2005-01-12 08:49:33 UTC]

I have created a new release of lzma that contains the GCC 3.4.x compatibility patch, and the makefile build system compatibility patch:

http://martinus.geekisp.com/files/lzma-0.03.tar.gz

I have updated the ebuild, but I am not shure if it works as I have no idea how to test ebuilds :-/

New ebuild for lzma 0.03

This should obsolete the patches and the previous ebuild

thank you for your contribution but due to upstream of lzma information about no further support, and possibility of fixing p7zip (which is maintained) to add support for -si and -so in one call, i hardly see benefits of inclusion lzma into portage, and would rather not do it. i sugest using portage overlay for this. will reconsider it this month, as for now, i'm not sure what to do.

[Comment 8 Mihai Limbasan 2005-01-14 13:08:10 UTC]

MArtin Ankerl is the LZMA author. He mentioned that he wouldn't further develop LZMA as it already accomplishes its purpose. But if p7zip gets fixed as you mentioned, I agree with not including it as it'd become moot.

[Comment 9 Radoslaw Stachowiak (RETIRED) 2005-02-19 02:10:33 UTC]

after some discussion with p7zip author, he pointed me to http://www.7-zip.org/sdk.html page for plain stream lzma usage. this is actively maintained, so if You want lzma support in portage, could you please use this? 

please write what you think about it.

P.S. p7zip (and 7z) wont have lzma-as-in-gzip.

[Comment 10 Martin Ankerl 2005-03-28 14:02:33 UTC]

I have just had a look at the LZMA SDK, it should be really easy to use this. The binary generated from this already is able to use stdin and stdout. If still someone is interested and capable of writing ebuilds, this would be nice.
The SDK can be found here: http://www.7-zip.org/sdk.html

i can write the ebuild, but unfortunatly, after decompressing http://www.7-zip.org/dl/lzma416.tar.bz2 and trying to do 'make' in  "SRC/7zip/Compress/LZMA_Alone" directory on my box i get pretty much long error messages related probably to missing MyGuidDef.h file.

If You can help me with this, we can try get it working together.

gcc 3.4.3 error message:
g++ -O2 -Wall -c -I ../../../ LzmaAlone.cpp
In file included from StdAfx.h:6,
                 from LzmaAlone.cpp:3:

LZMA SDK 4.26 working ebuild

Here is an ebuild to build the lzma single-file command-line program out of the
latest (version 4.27) LZMA SDK.  I have tested this on both x86 and amd64.

[Comment 13 Radoslaw Stachowiak (RETIRED) 2005-08-27 07:00:37 UTC]

thank you, commited into portage with only ~x86 keywords - please use
/etc/portage/package.keywords file for testing.
