android -- libcurl移植、编译与测试
1、移植Curl工具到 2.3 环境步骤
& &1、直接到网站上下载 curl
& &2、利用tar在android编译环境下，一般放在 external 目录下
& &3、由于Curl依赖一些一些头文件及定义需要先执行配置文件先，在external/curl 下面编译curl.sh
& & & 需要 cd external/curl/.curl.sh进行执行，或者放在android根目录下的*.sh脚本中执行：source external/curl/curl.sh
& & & 其中修改了相应的CURL路径及编译工具链路径等变量

#include &curl/curl.h&
#include &stdio.h&;
int main() {&
& & CURL *&
& & curl_global_init(CURL_GLOBAL_ALL);

& & if (curl) { & &&
& & & & curl_easy_setopt(curl, CURLOPT_URL, &/&); &
& & & & res = curl_easy_perform(curl);&
& & & & if (0!=res) { & & &
& & & & & & printf(&curl error: %d\n&, res); & & & &&
& & & & curl_easy_cleanup(curl); & &&
& & curl_global_cleanup();
& & return 0;
编译一个相应的android.mk生成可执行文件：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)&
LOCAL_C_INCLUDES += \
& & $(TOP)/external/curl/include/ \&
LOCAL_SRC_FILES:= curl_test.cpp
LOCAL_SHARED_LIBRARIES := libcurl
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := curl_test
include $(BUILD_EXECUTABLE)
即可进行测试的，输出的内容就是打开 / 页面的源代码
3、编译问题
& & & 请根据具体android版本及路径修改 curl.sh 文件并重新执行即可，暂时没碰到其它的问题。&>&&>&&>&&>&mac平台curl库源码编译libcurl

系统是fedora core5.0，可以YUM
請愛用 yum.
yum install curl curl-devel复制代码
若你要編譯連結使用 library 才需要裝 curl-devel
還有請不要用在線等這種描述，論壇不是給您即時諮詢的園地。

我是真的不怎么懂才来请教，提供的那几个网址都去看过了，可还是不是很明白
英语不是很好，也不清楚怎么装libcrul,自己试着装了几次都不行又不知道是哪里出了问题
希望能耐心点，我会虚心向学的

我先使用curl-config --cflags
curl-config --libs
curl-config --feature
yum install curl curl-devel这几个命令安装libcurl
结果编译 时还是出现问题是什么原因
[root@localhost example]# gcc -o wang wang.c
/tmp/ccfP2skF.o: In function `main':wang.c: (.text+0x12)：对‘curl_easy_init’未定 义的引用
:wang.c: (.text+0x36)：对‘curl_easy_setopt’未定义的引用
:wang.c: （.text+0x41)：对‘curl_easy_perform’未定义的引用
:wang.c: (.text+0x4f)：对‘curl_easy_cleanup’未定义的引用
collect2: ld 返回 1

fedora 上有收錄 curl，所以剛剛提供用 yum 即可安裝。或者是你可以學學基本系統管理的東西，把基礎 package 管理議題熟悉一下也不錯，這樣至少後續你要在系統上進形成是設計開發會比較輕鬆一點。
官方提供範例來看:
程式碼改一下，成為:
SayyaBBS:kendlee@~/tmp& cat -n simple.c
& &&&1&&/*& && && && && && && && && && && & _& &_ ____&&_
& &&&2& &*&&Project& && && && && && && &___| | | |&&_ \| |

& &&&5& &*& && && && && && && && && &&&\___|\___/|_| \_\_____|
& &&&6& &*
& &&&7& &* $Id: simple.c,v 1.6
14:22:52 bagder Exp $
& &&&8& &*/
& &&&9
& & 10&&#include &stdio.h&
& & 11&&#include &curl/curl.h&
& & 12
& & 13&&int main(void)
& & 14&&{
& & 15& & CURL *
& & 16& & CURL
& & 17
& & 18& & curl = curl_easy_init();
& & 19& & if(curl) {
& & 20& && &curl_easy_setopt(curl, CURLOPT_URL, &&);
& & 21& && &res = curl_easy_perform(curl);
& & 22
& & 23& && &/* always cleanup */
& & 24& && &curl_easy_cleanup(curl);
& & 25& & }
& & 26& & return 0;
& & 27&&}
& & 28
复制代码
編譯需要哪些程式庫？使用 curl --libs 看看...
curl-config --libs
-lcurl
复制代码
輸出只有連結使用 curl library 的話，那簡化編譯方式就是:
SayyaBBS:kendlee@~/tmp&
SayyaBBS:kendlee@~/tmp& ls -l
總計 4
-rw-rw-r-- 1 kendlee kendlee 624
18:09 simple.c
SayyaBBS:kendlee@~/tmp&
SayyaBBS:kendlee@~/tmp&
SayyaBBS:kendlee@~/tmp& gcc -lcurl simple.c
SayyaBBS:kendlee@~/tmp&
SayyaBBS:kendlee@~/tmp&
SayyaBBS:kendlee@~/tmp& ls -l
總計 12
-rwxrwxr-x 1 kendlee kendlee -08 18:10 a.out*
-rw-rw-r-- 1 kendlee kendlee&&624
18:09 simple.c
SayyaBBS:kendlee@~/tmp&
复制代码
若你要使用 gcc $(curl-config --libs) simple.c 也可以。
執行程式輸出結果:
SayyaBBS:kendlee@~/tmp& ./a.out
&HTML&&HEAD&&meta http-equiv=&content-type& content=&text/charset=utf-8&&
&TITLE&302 Moved&/TITLE&&/HEAD&&BODY&
&H1&302 Moved&/H1&
The document has moved
&A HREF=&.tw/&&here&/A&.
&/BODY&&/HTML&
复制代码
所以問題拉回來，其實您的問題主要還是對於 unix 基本 programming 的技巧比較不清楚，包含程式庫連結方式不清楚等，這克服學會後就都沒問題了。
