zlibとgzipの圧縮アーカイバーを作成。
http://www.zlib.net/　からzlib source codeをダウンロード(zipファイル)して解凍します。

この中のwin32のMakefile.mscをビルドします。
zlib.libが作成されます。

Menu->Microsoft VisualStudio2012->VisualStudio Tools->x86 NativeTools コマンﾄﾞプロンプトで以下を実行。

>cd xxx\zlib-1.2.8

>nmake -f win32/Makefile.msc

zlib.h、zconf.hとzlib.libを使用したサンプルが以下

#include "zlib.h"

#define CHUNK 16384

#pragma comment( lib, "zlib.lib" )

// 特定の規定のライブラリの無視: msvcrt.lib
bool GZIP::Compress( const byte* src, int src_len, std::stringstream& sm )

{

	z_stream strm;

		

	unsigned char out[CHUNK];

	unsigned char in[CHUNK];


	ZeroMemory( &strm, sizeof(strm));
	// zlib

	//int ret = deflateInit(&strm, Z_DEFAULT_COMPRESSION);

	

	// gzip

	int ret = deflateInit2(&strm,Z_DEFAULT_COMPRESSION, Z_DEFLATED, 31,8,Z_DEFAULT_STRATEGY);
	if (ret != Z_OK)

		return false;
