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

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)
