7-Zip Copyright (C) 1999-2016 Igor Pavlov.
7-Zip is free software distributed under the GNU LGPL
(except for unRar code).
read License.txt for more infomation about license.
Notes about unRAR license:
Please check main restriction from unRar license:
2. The unRAR sources may be used in any software to handle RAR
archives without limitations free of charge, but cannot be used
to re-create the RAR compression algorithm, which is proprietary.
Distribution of modified unRAR sources in separate form or as a
part of other software is permitted, provided that it is clearly
stated in the documentation and source comments that the code may
not be used to develop a RAR (WinRAR) compatible archiver.
In brief it means:
1) You can compile and use compiled files under GNU LGPL rules, since
unRAR license almost has no restrictions for compiled files.
You can link these compiled files to LGPL programs.
2) You can fix bugs in source code and use compiled fixed version.
3) You can not use unRAR sources to re-create the RAR compression algorithm.
This package also contains some files from LZMA SDK
You can download LZMA SDK from:
LZMA SDK is written and placed in the public domain by Igor Pavlov.
How to compile
To compile sources you need Visual C++ 6.0.
For compiling some files you also need
new Platform SDK from Microsoft' Site:
If you use MSVC6, specify SDK directories at top of directories lists:
Tools / Options / Directories
- Include files
- Library files
To compile 7-Zip for AMD64 and IA64 you need:
Windows Server 2003 SP1 Platform SDK from microsoft.com
Also you need Microsoft Macro Assembler:
- ml.exe for x86
- ml64.exe for AMD64
You can use ml.exe from Windows SDK for Windows Vista or some other version.
Compiling under Unix/Linux
Check this site for Posix/Linux version:
7-Zip consists of COM modules (DLL files).
But 7-Zip doesn't use standard COM interfaces for creating objects.
7zip\UI\Client7z folder for example of using DLL files of 7-Zip.
Some DLL files can use other DLL files from 7-Zip.
If you don't like it, you must use standalone version of DLL.
To compile standalone version of DLL you must include all used parts
to project and define some defs.
For example, 7zip\Bundles\Format7z is a standalone version of 7z.dll
that works with 7z format. So you can use such DLL in your project
without additional DLL files.
