-------------------

7-Zip is a file archiver for Windows. 

7-Zip Copyright (C) 1999-2018 Igor Pavlov.


License Info
------------

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.


LZMA SDK
--------

This package also contains some files from LZMA SDK
You can download LZMA SDK from:
  http://www.7-zip.org/sdk.html
LZMA SDK is written and placed in the public domain by Igor Pavlov.


How to compile
--------------

To compile the sources to Windows binaries you need Visual Studio compiler and/or Windows SDK.
You can use latest Windows Studio 2017 to compile binaries for x86, x64 and arm64 platforms.
Also you can use old compilers for some platforms:
  x86   : Visual C++ 6.0 with Platform SDK
  x64   : Windows Server 2003 R2 Platform SDK
  arm64 : Windows Studio 2017
  arm   : Windows Studio 2017
  ia64 (itanium)     : Windows Server 2003 R2 Platform SDK
  arm for Windows CE : Standard SDK for Windows CE 5.0

If you use MSVC6, specify also Platform SDK directories at top of directories lists:
Tools / Options / Directories
  - Include files
  - Library files

Also you need Microsoft Macro Assembler:
  - ml.exe for x86 
  - ml64.exe for x64
You can use ml.exe from Windows SDK for Windows Vista or some later versions.

There are two ways to compile 7-Zip binaries:
1) via makefile in command line.
2) via dsp file in Visual Studio.

The dsp file compiling can be used for development and debug purposes.
The final 7-Zip binaries are compiled via makefiles, that provide best 
optimization options.

How to compile with makefile
----------------------------

Some macronames can be defined for compiling with makefile:

PLATFORM
  with possible values: x64, x86, arm64, arm, ia64

OLD_COMPILER
  for old VC compiler, like MSCV 6.0.

MY_DYNAMIC_LINK
  for dynamic linking to the run-time library (msvcrt.dll). 
  The default makefile option is static linking to the run-time library.



Compiling under Unix/Linux
--------------------------

Notes:
------
7-Zip consists of COM modules (DLL files).
But 7-Zip doesn't use standard COM interfaces for creating objects.
Look at
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.
