I am trying to compile curl source code (version 7.22.0)under ubuntu 13.04 to import libcurl to Android platform. The Android source code (version Android-2.2_r1) has been already compiled successfully and environment for compiling curl has been set up successfully.
我试图在ubuntu 13.04下编译curl源代码(version 7.22.0)，将libcurl导入到Android平台。已经成功编译了Android源代码(Android-2.2_r1版本)，并成功地设置了编译curl的环境。
Compiling environment:
编译环境:
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
The following is the configure command for setting up compiling environment for libcurl:

after executing the config command, I can see following content from the config.log file under external/curl directory that
执行配置命令后，我可以从配置中看到以下内容。在外部/curl目录下的日志文件。
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
I also checked the directory : $NDK_HOME/platforms/android-14/arch-arm/usr/include and make sure zlib.h file does exist there.
我还检查了目录:$NDK_HOME/平台/android-14/ archarm /usr/包括并确保zlib。h文件确实存在。
Problem: when I tried to compile libcurl using commands make libcurl, the compliation fails. And the error I got is:
问题:当我试图使用命令来编译libcurl时，遵从性就会失败。我得到的错误是:
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'
It really makes me upset since the file does exist and found at the configuration step.
因为文件确实存在，并且在配置步骤中找到，所以我很沮丧。
Solution attempt: I tried to add the absolute path of zlib.h file in NDK_HOME to Android.mk file which locates at external/curl directory like the following.
解决方案尝试:我尝试添加zlib的绝对路径。h文件在NDK_HOME到Android。位于外部/curl目录的mkfile，如下所示。
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include/ /home/kevin/Software/android-ndk-r8e/platforms/android-14/arch-arm/usr/include
It turns out the errors are gone and compliation is successful, but when using the curl library in the program, the following error happens:
结果表明，错误已经消失，遵从性是成功的，但是当在程序中使用curl库时，会发生以下错误:
/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_'
Anyone has the same problem? Any help is greatly appreciated.
有人有同样的问题吗?非常感谢您的帮助。

Looks like you are missing -lz when building your program.
看起来你在构建程序时缺少了-lz。
