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

Question

我正在嘗試在ubuntu 13.04下編譯curl源代碼（7.22.0版），以將libcurl導入Android平台。 Android源代碼（版本Android-2.2_r1）已成功編譯，並且已成功設置curl的編譯環境。

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

以下是用於為libcurl設置編譯環境的configure命令：

執行config命令后，我可以從external / curl目錄下的config.log文件中看到以下內容：

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

我還檢查了目錄： $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make libcurl命令編譯libcurl時，編譯失敗。 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'

由於文件確實存在並且在配置步驟中找到了文件，這確實讓我感到沮喪。

解決方案嘗試：我嘗試將NDK_HOME中zlib.h文件的絕對路徑添加到位於external / curl目錄的Android.mk文件中，如下所示。

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

事實證明錯誤消失了，並且編譯成功，但是在程序中使用curl庫時，發生以下錯誤：

/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_'

有人有同樣的問題嗎？ 任何幫助是極大的贊賞。

看起來在構建程序時缺少-lz。
