1Building instructions for the DLL versions of Zlib 1.2.3 2======================================================== 3 4This directory contains projects that build zlib and minizip using 5Microsoft Visual C++ 7.0/7.1, and Visual C++ . 6 7You don't need to build these projects yourself. You can download the 8binaries from: 9 http://www.winimage.com/zLibDll 10 11More information can be found at this site. 12 13 14Build 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). 22 23Build 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 30 31Build instructions for Visual Studio 2005 64 bits, PSDK compiler 32---------------------------------------------------------------- 33at the time of writing this text file, Visual Studio 2005 (and 34 Microsoft Visual C++ 8.0) is on the beta 2 stage. 35Using 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 37see http://www.winimage.com/misc/sdk64onvs2005/ for instruction 38 39- Uncompress current zlib, including all contrib/* files 40- start Visual Studio 2005 from a platform SDK command prompt, using 41 the /useenv switch 42- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0 43 44 45Important 46--------- 47- To use zlibwapi.dll in your application, you must define the 48 macro ZLIB_WINAPI when compiling your application's source files. 49 50 51Additional notes 52---------------- 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. 59 60- The new DLL was renamed because there exist several incompatible 61 versions of zlib.dll on the Internet. 62 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. 66 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 69 not define it here. 70 71 72Gilles Vollant 73info@winimage.com 74
