android-ndk-r10 编译 curl

这里只讲curl是如何编译的关于ssl zlib 其他的自行查找方式

下载源curl源码 http://curl.haxx.se/download.html

C库：curl-7.46.0

目标平台：android

编译平台：win7

编译工具：ndk r10

编译过程

1、随手创建一个eclipse的android项目,记得在源码中增加jni目录,写过ndk的朋友都知道

2、构建curl编译目录,下面所指向的目录均以上面创建的jni目录为根结构,因为最后我们执行ndk-build命令也是在此目录

｛1｝把正解好的curl源码解压,把目录改名为curl,并复制到jni目录下

｛2｝在jni目录创建 Android.mk 并复制下面的内容

 1 LOCAL_PATH:= $(call my-dir)
 2 
 3 CFLAGS := -Wpointer-arith -Wwrite-strings -Wunused -Winline 
 4  -Wnested-externs -Wmissing-declarations -Wmissing-prototypes -Wno-long-long 
 5  -Wfloat-equal -Wno-multichar -Wsign-compare -Wno-format-nonliteral 
 6  -Wendif-labels -Wstrict-prototypes -Wdeclaration-after-statement 
 7  -Wno-system-headers -DHAVE_CONFIG_H
 8 
 9 include $(CLEAR_VARS)
10 include $(LOCAL_PATH)/curl/lib/Makefile.inc
11 
12 
13 LOCAL_SRC_FILES := $(addprefix curl/lib/,$(CSOURCES))
14 LOCAL_CFLAGS += $(CFLAGS)
15 LOCAL_C_INCLUDES += $(LOCAL_PATH)/curl/include/ $(LOCAL_PATH)/curl/lib
16 
17 LOCAL_COPY_HEADERS_TO := libcurl
18 LOCAL_COPY_HEADERS := $(addprefix curl/include/curl/,$(HHEADERS))
19 
20 LOCAL_MODULE:= libcurl
21 
22 include $(BUILD_STATIC_LIBRARY)

View Code

｛3｝在jni目录创建 Application.mk 并复制下面的内容

APP_ABI :=  x86 armeabi armeabi-v7a

最后目录结构如下

jni
 |-Android.mk 
 |-Application.mk
 |-curl(这里为curl源码目录)

3 、构建config.h文件其实就是在linux下使用./configurl生成的config.h文件在这里我们手动构建

在jni/curl/lib/下创建curl_config.h文件并复制下面源码直接覆盖就好了源码来源于 http://www.cnblogs.com/stratrail/archive/2013/04/12/3016663.html 感谢这位大神,虽然我用他介绍的方式没有编译成功

4、下面我们就打开cmd 窗口进入 android项目中的jni目录

执行 ndk-bulid 激动人心的时刻就这样来临了生成后的静态库在android项目中的 obj目录中

至此我也只是成功编译了静态库有任何其他的问题大家可以一起到 25093009 NDK JNI android开发交流群,大家一起交流讨论

5、

关于静态编译似乎有个误区我在尝试

LOCAL_STATIC_LIBRARIES := $(LOCAL_PATH)/curl/$(TARGET_ARCH_ABI)/libcurl.a

编译的时候始终会提供找没有定义的函数

一定需要这样子写

LOCAL_LDFLAGS := $(LOCAL_PATH)/curl/$(TARGET_ARCH_ABI)/libcurl.a

才会正常但是ndk-build的时候会报一个警告单单的忧伤

贴一下测试项目的代码
