7-Zip for Linux has been released (by Igor Pavlov)

teoberi · 11-26-2021, 01:00 AM

If any of those experienced with slackbuild (Heinz Wiesinger, @alienbob, @ponce) are interested in reviving p7zip (now 7-Zip for Linux) and even for a possible integration into Slackware, I let you know that Igor Pavlov has released version 7-Zip 21.06 for Linux.
This version compiles cleanly into Slackware64-current with and without Asmc.

The compilation instructions can be found in the readme.txt file (DOC folder)

.

Unless the unrar license restrictions are lifted, there's very little chance this will ever be accepted as part of Slackware.

7-Zip 21.07 for Linux is released.

The following changes have been made:
1. The source code can be found in .tar.xz format at the web address:
https://www.7-zip.org/download.html
2. Clarifications/changes have been made to the configuration of the unrar support.
7z2107-src\DOC\readme.txt

Quote:

DISABLE_RAR=1
removes whole RAR related code from compilation.

DISABLE_RAR_COMPRESS=1
removes "not fully free" code of RAR decompression codecs from compilation.

RAR decompression codecs in 7-Zip code has some additional license restrictions,
that can be treated as not fully compatible with free-software licenses.
DISABLE_RAR_COMPRESS=1 allows to exclude such "not-fully-free" RAR code from compilation.
if DISABLE_RAR_COMPRESS=1 is specified, 7-zip will not be able to decompress files
from rar archives, but 7-zip still will be able to open rar archives to get list of
files or to extract files that are stored without compression.
if DISABLE_RAR=1 is specified, 7-zip will not be able to work with RAR archives.

Compiling in this case can be done with the commands:

Code:

cd CPP/7zip/Bundles/Alone2

Code:

make -f ../../cmpl_gcc.mak DISABLE_RAR=1

or

Code:

make -f ../../cmpl_gcc.mak DISABLE_RAR_COMPRESS=1

Can be verified with command: b/g/7zz i
The other two executables can be compiled:
CPP/7zip/Bundles/Alone -> 7za
CPP/7zip/Bundles/Alone7z -> 7zr
7zz, 7za, 7zr -> /usr/bin/
7-Zip for Linux is already present in Arch Linux, OpenSUSE (without support for unrar) and Debian.
Now, I'm not discussing compiling using Asmc or UASM assembler (for faster 7-Zip binary).

Yes, I am one of those people!

I have spent some time in the last few months for 7-Zip, Asmc and UASM until I get a viable solution to replace p7zip.

7-Zip 21.07 compiles cleanly into Slackware64-current using even UASM 2.49 (Linux 64bit) from here.

I think I have something to add.
7-Zip 24.02 is interesting, here more information.
To remember:
1. Debian Trixie uses 7-zip to replace p7zip see comment https://sourceforge.net/p/sevenzip/d...2ab8b42c/#2885;
2. even Windows 11 uses the 7z format.
Check here and here

In addition…
We have added native support for additional archive formats, including tar, 7-zip, rar, gz and many others using the libarchive open-source project. You now can get improved performance of archive functionality during compression on Windows.
