| 4 | This directory contains projects that build zlib and minizip using
|
|---|
| 5 | Microsoft Visual C++ 7.0/7.1, and Visual C++ .
|
|---|
| 6 |
|
|---|
| 7 | You don't need to build these projects yourself. You can download the
|
|---|
| 8 | binaries from:

| 14 | 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).
|
|---|
| 22 |
|
|---|
| 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
|
|---|
| 30 |
|
|---|
| 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
|
|---|
| 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 |
|
|---|
| 45 | Important
|
|---|
| 46 | ---------
|
|---|
| 47 | - To use zlibwapi.dll in your application, you must define the
|
|---|
| 48 | macro ZLIB_WINAPI when compiling your application's source files.
|

|

|
|---|
| 51 | Additional 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.
