This directory contains a .Net wrapper class library for the ZLib1.dll
The wrapper includes support for inflating/deflating memory buffers,
.Net streaming wrappers for the gz streams part of zlib, and wrappers
for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
Directory structure:
--------------------
LICENSE_1_0.txt - License file.
readme.txt - This file.
DotZLib.chm - Class library documentation
DotZLib.build - NAnt build file
DotZLib.sln - Microsoft Visual Studio 2003 solution file
DotZLib\*.cs - Source files for the class library
Unit tests:
-----------
The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
To include unit tests in the build, define nunit before building.
Build instructions:
-------------------
1. Using Visual Studio.Net 2003:
Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
you are building the release or debug version of the library. Check
DotZLib/UnitTests.cs for instructions on how to include unit tests in the
build.
2. Using NAnt:
Open a command prompt with access to the build environment and run nant
in the same directory as the DotZLib.build file.
You can define 2 properties on the nant command-line to control the build:
debug={true|false} to toggle between release/debug builds (default=true).
nunit={true|false} to include or esclude unit tests (default=true).
Also the target clean will remove binaries.
Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
or ./DotZLib/bin/debug, depending on whether you are building the release
or debug version of the library.
Examples:
nant -D:debug=false -D:nunit=false
will build a release mode version of the library without unit tests.
nant
will build a debug version of the library with unit tests
nant clean
will remove all previously built files.
