Building instructions for the DLL versions of Zlib 1.21 | |
======================================================= | |
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 | |
More information can be found at this site. | |
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). | |
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. | |
