1Building instructions for the DLL versions of Zlib 1.2.8
2========================================================

4This directory contains projects that build zlib and minizip using
5Microsoft Visual C++ 9.0/10.0.

7You don't need to build these projects yourself. You can download the
8binaries from:

17Build instructions for Visual Studio 2008 (32 bits or 64 bits)
18--------------------------------------------------------------
19- Uncompress current zlib, including all contrib/* files
20- Compile assembly code (with Visual Studio Command Prompt) by running:
21   bld_ml64.bat (in contrib\masmx64)
22   bld_ml32.bat (in contrib\masmx86)
23- Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008
24- Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32"
25
26Build instructions for Visual Studio 2010 (32 bits or 64 bits)
27--------------------------------------------------------------
28- Uncompress current zlib, including all contrib/* files
29- Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010
30
31Build instructions for Visual Studio 2012 (32 bits or 64 bits)
32--------------------------------------------------------------
33- Uncompress current zlib, including all contrib/* files
34- Open contrib\vstudio\vc11\zlibvc.sln with Microsoft Visual C++ 2012

37Important
38---------
39- To use zlibwapi.dll in your application, you must define the
40  macro ZLIB_WINAPI when compiling your application's source files.

43Additional notes
44----------------
45- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
46  by Gilles Vollant from the zlib 1.1.x sources, and distributed at
47    http://www.winimage.com/zLibDll
48  It uses the WINAPI calling convention for the exported functions, and
49  includes the minizip functionality. If your application needs that
50  particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
51
52- The new DLL was renamed because there exist several incompatible
53  versions of zlib.dll on the Internet.
54
55- There is also an official DLL build of zlib, named zlib1.dll. This one
56  is exporting the functions using the CDECL convention. See the file
57  win32\DLL_FAQ.txt found in this zlib distribution.
58
59- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
60  has a slightly different effect. To avoid compatibility problems, do
61  not define it here.
