本文解决了一个在Cocos2d-x项目中遇到的问题，即使用OpenSSL时出现的编译错误。通过修改jni的Android.mk文件，指定了正确的头文件路径和库文件路径后，成功解决了编译过程中的fatal error和链接阶段的invalid character问题。

一、执行 build_native.sh 时报错了（项目中使用到了 openssl，胡乱找了些头文件丢在库目录里面）
=========================================================================================
sogas-Mac-mini:~ soga$ /Users/soga/Desktop/cocos2d-x-2.2.3/projects/CatchMonkey/proj.android/build_native.sh
NDK_ROOT = /Users/soga/Downloads/android-ndk-r8e
COCOS2DX_ROOT = /Users/soga/Desktop/cocos2d-x-2.2.3/projects/CatchMonkey/proj.android/../../..
APP_ROOT = /Users/soga/Desktop/cocos2d-x-2.2.3/projects/CatchMonkey/proj.android/..
APP_ANDROID_ROOT = /Users/soga/Desktop/cocos2d-x-2.2.3/projects/CatchMonkey/proj.android

make: Leaving directory `/Users/soga/Desktop/cocos2d-x-2.2.3/projects/CatchMonkey/proj.android'

二、在 jni 的 Android.mk 中加入如下行
=========================================================================================
LOCAL_C_INCLUDES :=$(LOCAL_PATH)/../../Classes \
/Users/soga/Downloads/openssl-1.0.1h/include \
LOCAL_LDFLAGS := $(LOCAL_PATH)/../../libs.cpp/libcrypto.a \
$(LOCAL_PATH)/../../libs.cpp/libsqlcipher.a

三、再执行的时候编译顺利通过了（坑爹的，等 link 的时候就跟老子说 invalid character，因为 .a 文件的架构不是 armeabi）
=========================================================================================
