|  | Building instructions for the DLL versions of Zlib 1.2.8 | 
|  | ======================================================== | 
|  |  | 
|  | This directory contains projects that build zlib and minizip using | 
|  | Microsoft Visual C++ 9.0/10.0. | 
|  |  | 
|  | You don't need to build these projects yourself. You can download the | 
|  | binaries from: | 
|  | http://www.winimage.com/zLibDll | 
|  |  | 
|  | More information can be found at this site. |

|  | Build instructions for Visual Studio 2008 (32 bits or 64 bits) | 
|  | -------------------------------------------------------------- | 
|  | - Uncompress current zlib, including all contrib/* files | 
|  | - Compile assembly code (with Visual Studio Command Prompt) by running: | 
|  | bld_ml64.bat (in contrib\masmx64) | 
|  | bld_ml32.bat (in contrib\masmx86) | 
|  | - Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008 | 
|  | - Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32" | 
|  |  | 
|  | Build instructions for Visual Studio 2010 (32 bits or 64 bits) | 
|  | -------------------------------------------------------------- | 
|  | - Uncompress current zlib, including all contrib/* files | 
|  | - Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010 | 
|  |  | 
|  | Build instructions for Visual Studio 2012 (32 bits or 64 bits) | 
|  | -------------------------------------------------------------- | 
|  | - Uncompress current zlib, including all contrib/* files | 
|  | - Open contrib\vstudio\vc11\zlibvc.sln with Microsoft Visual C++ 2012 | 
|  |  | 
|  |  | 
|  | 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. |
