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

| 14 | Build instructions
|
|---|
| 15 | ------------------
|
|---|
| 16 | - Unzip zlib*.zip and copy the files from contrib\vstudio\vc7,
|
|---|
| 17 | from contrib\vstudio\masmx86 and from contrib\minizip into the same
|
|---|
| 18 | directory.
|
|---|
| 19 | - Download the crtdll library from
|
|---|
| 20 | http://www.winimage.com/zLibDll/crtdll.zip
|
|---|
| 21 | Unzip crtdll.zip to extract crtdll.lib.
|
|---|
| 22 | - If you are using x86, use the Release target.
|
|---|
| 23 | - Open zlibvc.sln with Microsoft Visual C++ 7.0 or 7.1
|
|---|
| 24 | (Visual Studio .Net 2002 or 2003).
|
|---|
| 25 |

|
|---|
| 27 | Important
|
|---|
| 28 | ---------
|
|---|
| 29 | - To use zlibwapi.dll in your application, you must define the
|
|---|
| 30 | macro ZLIB_WINAPI when compiling your application's source files.
|
|---|
| 31 |
|
|---|
| 32 |
|
|---|
| 33 | Additional notes
|
|---|
| 34 | ----------------
|
|---|
| 35 | - This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
|
|---|
| 36 | by Gilles Vollant from the zlib 1.1.x sources, and distributed at
|
|---|
| 37 | http://www.winimage.com/zLibDll
|
|---|
| 38 | It uses the WINAPI calling convention for the exported functions, and
|
|---|
| 39 | includes the minizip functionality. If your application needs that
|
|---|
| 40 | particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
|
|---|
| 41 |
|
|---|
| 42 | - The new DLL was renamed because there exist several incompatible
|
|---|
| 43 | versions of zlib.dll on the Internet.
|
|---|
| 44 |
|
|---|
| 45 | - There is also an official DLL build of zlib, named zlib1.dll. This one
|
|---|
| 46 | is exporting the functions using the CDECL convention. See the file
|
|---|
| 47 | win32\DLL_FAQ.txt found in this zlib distribution.
|
|---|
| 48 |
|
|---|
| 49 | - There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
|
|---|
| 50 | has a slightly different effect. To avoid compatibility problems, do
|
|---|
| 51 | not define it here.
