在Ubuntu下編譯LibCurl時出錯：zlib.h：沒有這樣的文件或目錄

Question

我想在Ubuntu 13.04下編譯curl源代碼（版本7.22.0）以將libcurl導入到Android平臺。 Android源代碼（版本Android-2.2_r1）已經編譯成功，編譯curl的環境已經成功建立。

編譯環境：

Android Source Code version: 2.2_r1 
    NDK Version:android-ndk-r8e 
    Curl Souce Code version:7.22.0 
    GCC version:4.4.7 
    JDK version:1.5.0_21 

下面是與libcurl設置編譯環境的配置命令：

執行config命令後，我可以看到下列從配置內容。日誌文件在外部/捲曲目錄下

configure:21303: checking zlib.h usability 
configure:21303: $? = 0 
configure:21303: result: yes 

configure:21303: checking zlib.h presence 
configure:21303: $? = 0 
configure:21303: result: yes 

configure:21303: checking for zlib.h 
configure:21303: result: yes 
configure:21384: found both libz and libz.h header 

我也檢查了目錄：$NDK_HOME/platforms/android-14/arch-arm/usr/include並確保zlib.h文件確實存在。

問題：當我嘗試使用命令make libcurl編譯libcurl時，編譯失敗。而我得到的錯誤是：

In file included from external/curl/lib/base64.c:30: 
external/curl/lib/urldata.h:141:59: error: zlib.h: No such file or directory 
In file included from external/curl/lib/base64.c:30: 
external/curl/lib/urldata.h:585: error: expected specifier-qualifier-list before 'z_stream' 

這真的讓我心煩，因爲該文件確實存在，並在配置步驟中發現。

解決方案的嘗試： 我嘗試添加在NDK_HOME zlib.h文件的絕對路徑的Android.mk文件，它座落於像下面這樣外部/捲曲目錄。

LOCAL_C_INCLUDES += $(LOCAL_PATH)/include/ /home/kevin/Software/android-ndk-r8e/platforms/android-14/arch-arm/usr/include 

原來的錯誤都不見了，compliation是成功的，但是在程序中使用curl庫時，下面的錯誤發生：

/home/kevin/Software/android-ndk-r8e/platforms/android-14/arch-arm/usr/lib/libcurl.a(content_encoding.o): in function Curl_unencode_deflate_write:external/curl/lib/content_encoding.c:180: error: undefined reference to 'inflateInit_' 

任何人有同樣的問題？任何幫助是極大的讚賞。

在構建程序時看起來像缺少-lz。
