Building instructions for the DLL versions of Zlib 1.2.3

========================================================

This directory contains projects that build zlib and minizip using
5
Microsoft Visual C++ 7.0/7.1, and Visual C++ .

You don't need to build these projects yourself. You can download the

Build instructions for Visual Studio 7.x (32 bits)
15
--------------------------------------------------
16
- Uncompress current zlib, including all contrib/* files
17
- Download the crtdll library from
18
http://www.winimage.com/zLibDll/crtdll.zip
19
Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc7.
20
- Open contrib\vstudio\vc7\zlibvc.sln with Microsoft Visual C++ 7.x
21
(Visual Studio .Net 2002 or 2003).
23
Build instructions for Visual Studio 2005 (32 bits or 64 bits)
24
--------------------------------------------------------------
25
- Uncompress current zlib, including all contrib/* files
26
- For 32 bits only: download the crtdll library from
27
http://www.winimage.com/zLibDll/crtdll.zip
28
Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc8.
29
- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
31
Build instructions for Visual Studio 2005 64 bits, PSDK compiler
32
----------------------------------------------------------------
33
at the time of writing this text file, Visual Studio 2005 (and
34
Microsoft Visual C++ 8.0) is on the beta 2 stage.
35
Using you can get the free 64 bits compiler from Platform SDK,
36
which is NOT a beta, and compile using the Visual studio 2005 IDE
37
see http://www.winimage.com/misc/sdk64onvs2005/ for instruction
39
- Uncompress current zlib, including all contrib/* files
40
- start Visual Studio 2005 from a platform SDK command prompt, using
42
- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
47
- To use zlibwapi.dll in your application, you must define the
48
macro ZLIB_WINAPI when compiling your application's source files.
53
- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
54
by Gilles Vollant from the zlib 1.1.x sources, and distributed at
55
http://www.winimage.com/zLibDll
56
It uses the WINAPI calling convention for the exported functions, and
57
includes the minizip functionality. If your application needs that
58
particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
60
- The new DLL was renamed because there exist several incompatible
61
versions of zlib.dll on the Internet.
63
- There is also an official DLL build of zlib, named zlib1.dll. This one
64
is exporting the functions using the CDECL convention. See the file
65
win32\DLL_FAQ.txt found in this zlib distribution.
67
- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
68
has a slightly different effect. To avoid compatibility problems, do
