cocosjs jsbinding笔记

IOS

步骤

在cocos2d/cocos/scripting/js-bindings/proj.ios_mac/目录中复制自带的工程，改成自己需要的名称。
在cocos2d/tools/tojs/中创建ini，直接从现有ini拷贝一个，修改文件名以及编译相关参数，文件路径等等。
在cocos2d/tools/tojs/创建py文件，直接将genbindings.py拷贝一份，修改文件吗，以及修改cmd_args为新建的ini文件
修改cocos2d/tools/bindings-generator/clang/目录cindex.py的bug。第3395行library = cdll.LoadLibrary(self.get_filename())改为library = cdll.LoadLibrary("../bindings-generator/libclang/" + self.get_filename())
执行cocos2d/tools/tojs/中的py生产auto文件。
自定义头文件加到jsext.h

# templates

# create a target namespace (in javascript, this would create some code like the equiv. to `ns = ns || {}`)

默认python版本编译出错解决

进入cocos2d/tools/tojs/执行
python genbindings.js

报错： Import Error: No module named yaml

解决：执行 sudo easy_install pyyaml

报错： Cheetah。。。
解决：下载cheetahtemplate-cheetah-v2.4.0.0.zip
进入目录，执行:sudo python setup.py install

Android

步骤

创建Android.mk
修改cocos2d/cocos/scripting/js-bindings/proj.android/Android.mk，在LOCAL_C_INCLUDES中加上导出的头文件目录，LOCAL_STATIC_LIBRARIES加上本lib的名称，最后加上
$(call import-module,jsext)，如下所示

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../manual 
                    $(LOCAL_PATH)/../../../../jsext 
	                $(LOCAL_PATH)/../../../../jsext/alipay/ 
	                $(LOCAL_PATH)/../../../../jsext/system/ 
	                $(LOCAL_PATH)/../../../../jsext/video/ 
	                $(LOCAL_PATH)/../../../../jsext/webview/ 
	                $(LOCAL_PATH)/../../../../jsext/umeng/

LOCAL_STATIC_LIBRARIES += cocos_jsext_static

$(call import-module,jsext)

LOCAL_SRC_FILES加上auto.cpp，如下所示
LOCAL_SRC_FILES := ../auto/jsb_cocos2dx_blank_auto.cpp ../auto/jsb_jsext_auto.cpp
3. 调用项目中添加头文件头文件目录

Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE    := cocos_jsext_static

LOCAL_MODULE_FILENAME := libjsext

ifeq ($(USE_ARM_MODE),1)
LOCAL_ARM_MODE := arm
endif

LOCAL_SRC_FILES := 
    ext1.cpp 
	alipay/AlipayUtil-android.cpp 
	system/SysUtil-android.cpp 
	umeng/UMUtil.cpp 
	video/VideoUtil.cpp 
	webview/WebviewUtil.cpp

				   
LOCAL_EXPORT_C_INCLUDES :=  $(LOCAL_PATH)/ 
	                $(LOCAL_PATH)/alipay/ 
	                $(LOCAL_PATH)/system/ 
	                $(LOCAL_PATH)/video/ 
	                $(LOCAL_PATH)/webview/ 
	                $(LOCAL_PATH)/umeng/

LOCAL_C_INCLUDES := $(LOCAL_PATH)/ 
					$(LOCAL_PATH)/../cocos/ui 
					$(LOCAL_PATH)/umeng/UMCocos2dxAnalyticsNative_no_idfa/android/libmobclickcpp/include/ 
	                $(LOCAL_PATH)/alipay/ 
	                $(LOCAL_PATH)/system/ 
	                $(LOCAL_PATH)/video/ 
	                $(LOCAL_PATH)/webview/ 
	                $(LOCAL_PATH)/umeng/

LOCAL_STATIC_LIBRARIES := cocos2dx_static

#LOCAL_CXXFLAGS += -fexceptions

#LOCAL_EXPORT_C_INCLUDES := 
                    
include $(BUILD_STATIC_LIBRARY)

Android.mk 2

编译成功后，在项目的proj.android/obj/local/armeabi/目录下可以找到lib，复制到代码目录，将mk文件修改为如下，在下次编译时，lib将不再编译。

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE    := cocos_jsext_static

LOCAL_MODULE_FILENAME := libjsext

ifeq ($(USE_ARM_MODE),1)
LOCAL_ARM_MODE := arm
endif

LOCAL_SRC_FILES := libjsext.a
LOCAL_EXPORT_C_INCLUDES :=  $(LOCAL_PATH)/
LOCAL_C_INCLUDES := $(LOCAL_PATH)/

include $(PREBUILT_STATIC_LIBRARY)
