-For create the 16 and 32 bits DLL of Zlib 1.20

+Building instructions for the DLL versions of Zlib 1.21

+=======================================================

 

-For the 16 bits :

-unzip zlib120.zip and copy file from contrib\vstudio\vc15_16 and from contrib\minizip in the same directory

-open zlib16.mak with Microsoft Visual C++ 1.52

+This directory contains projects that build zlib and minizip using

+Microsoft Visual C++ 7.0/7.1.

 

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

+binaries from:

+  http://www.winimage.com/zLibDll

 

-For the 32 bits :

-unzip zlib120.zip and copy file from contrib\vstudio\vc70_32 and from contrib\minizip in the same directory

-You can also need unzip http://www.winimage.com/zLibDll/crtdll.zip

+More information can be found at this site.

 

-If you are using x86, use target Release

-open zlibvc.sln with Microsoft Visual C++ 7.0 (Visual Studio .net)

 

+Build instructions

+------------------

+- Unzip zlib*.zip and copy the files from contrib\vstudio\vc7,

+  from contrib\vstudio\masmx86 and from contrib\minizip into the same

+  directory.

+- Download the crtdll library from

+    http://www.winimage.com/zLibDll/crtdll.zip

+  Unzip crtdll.zip to extract crtdll.lib.

+- If you are using x86, use the Release target.

+- Open zlibvc.sln with Microsoft Visual C++ 7.0 or 7.1

+  (Visual Studio .Net 2002 or 2003).

 

-Note : You don't need recompile yourself. There is compiled .LIB in

-  http://www.winimage.com/zLibDll . See this page for more information

 

+Important

+---------

+- To use zlibwapi.dll in your application, you must define the

+  macro ZLIB_WINAPI when compiling your application's source files.

+

+

+Additional notes

+----------------

+- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built

+  by Gilles Vollant from the zlib 1.1.x sources, and distributed at

+    http://www.winimage.com/zLibDll

+  It uses the WINAPI calling convention for the exported functions, and

+  includes the minizip functionality. If your application needs that

+  particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.

+

+- The new DLL was renamed because there exist several incompatible

+  versions of zlib.dll on the Internet.

+

+- There is also an official DLL build of zlib, named zlib1.dll. This one

+  is exporting the functions using the CDECL convention. See the file

+  win32\DLL_FAQ.txt found in this zlib distribution.

+

+- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol

+  has a slightly different effect. To avoid compatibility problems, do

+  not define it here.
