android -- libcurl移植、編譯與測試

      1、移植Curl工具到Android 2.3 環境步驟      1、直接到網站上下載 curl 源碼      2、利用tar在android編譯環境下，一般放在 external 目錄下      3、由於Curl依賴一些一些頭文件及定義需要先執行配置文件先，在external/curl 下面編譯curl.sh         需要 cd external/curl/.curl.sh進行執行，或者放在android根目錄下的*.sh腳本中執行：source external/curl/curl.sh         其中修改了相應的CURL路徑及編譯工具鏈路徑等變量   [cpp]   #!/bin/bash       ANDROID_HOME_CURL=../../ && \   NDK_HOME_CURL=../../ndk
