VC++ 編譯libcurl 支援SSL,GZIP（有指令碼）
由於網上下載的 libcurl 不支援 gzip，只好自己動手編譯，期間走了很多彎路，下面是最終成功的記錄。
我所使用的環境 Visual Studio 2010 、 Windows 7 64 bit
下載檔案
libcurl
下載頁面 http://curl.haxx.se/download.html
下載地址 http://curl.haxx.se/download/curl-7.26.0.zip
zlib
下載頁面 http://sourceforge.net/projects/libpng/files/zlib/
下載地址 http://sourceforge.net/projects/libpng/files/zlib/1.2.5/zlib125.zip/download
openssl
下載頁面 http://www.openssl.org/source/
下載地址 http://www.openssl.org/source/openssl-1.0.0c.tar.gz
編譯openssl還需下載ActivePerl
官方下載 http://www.activestate.com/activeperl/downloads
下載地址：http://downloads.activestate.com/ActivePerl/releases/5.16.0.1600/ActivePerl-5.16.0.1600-MSWin32-x86-295879.msi
X64下載地址：http://downloads.activestate.com/ActivePerl/releases/5.16.0.1600/ActivePerl-5.16.0.1600-MSWin32-x64-295879.msi
解壓及安裝檔案
ActivePerl安裝，雙擊直接下一步，預設設定到底。
zlib openssl libcurl分別解壓，他們三個在同一級目錄。
例如：D:UserDeweiTestCurlcurl-7.26.0、D:UserDeweiTestCurlopenssl-1.0.0c、D:UserDeweiTestCurlzlib-1.2.5
編譯過程
zlib編譯
用vs2010開啟zlib-1.2.5/old/visualc6/zlib.dsw，選擇DLL_Release編譯，把編譯生成的zlib-1.2.5/old/visualc6/Win32_DLL_Release/ zlib1.lib 複製到curl-7.26.0/lib目錄下，重新命名為 zdll.lib （注意必須為此檔名） 。
openssl編譯
開啟cmd，cd到openssl-1.0.0c目錄下；
執行命令 perl Configure VC-WIN32
再執行 msdo_ms.bat
再執行 “C:Program Files (x86)Microsoft Visual Studio 10.0vcvars32.bat”
執行命令 nmake -f ms/ntdll.mak
編譯curl-7.26.0
在curl-7.26.0/lib目錄下新建release.bat,輸入以下內容
call “C:/Program Files/Microsoft Visual Studio 10.0/VC/bin/vcvars32.bat”
set CFG=release-dll-ssl-dll-zlib-dll
set OPENSSL_PATH=../../openssl-1.0.0c
set ZLIB_PATH=../../zlib-1.2.5
nmake -f Makefile.vc10
儲存，然後執行。
等待一會兒，就可以到 curl-7.26.0librelease-dll-ssl-dll-zlib-dll 目錄下拷檔案 libcurl_imp.lib和libcurl.dll 啦！
