cocos2d-x 3.0rc1 使用iconv库 解决UTF8乱码问题
来源:互联网 发布:公司宣传画册设计软件 编辑:程序博客网 时间:2024/06/16 01:52
多国语言要用到开源字符转换 iconv
先贴出自己的使用代码 你可以做成头文件

注意设置安卓版本的路径和win32版本的路径
win32版本是rc1版本里面有的自带iocnv.h头文件和lib
但是Android版本需要自己下载
1.下载
在windows上用iconv.dll,在IOS上系统有提供这个库,导入就可以,在android上要自己去下一个。
http://ftp.gnu.org/pub/gnu/libiconv/
这个是官网地址,目前iconv最新版本是1.14,2011.8.7版本的,大小4.8M
官方地址:
http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
2.下载完毕,解压放到E:\MyCocos\cocos2dx-workspace\hello\cocos2d目录下(这里是我自己的目录),改名为iconv,和cocos,extensions,external等同目录
3.在iconv目录下增加Android.mk文件,写入
LOCAL_PATH:= $(call my-dir)#libiconv.soinclude $(CLEAR_VARS)LOCAL_MODULE := iconv_staticLOCAL_MODULE_FILENAME := libiconvLOCAL_CFLAGS := \ -Wno-multichar \ -DAndroid \ -DLIBDIR="c" \ -DBUILDING_LIBICONV \ -DIN_LIBRARYLOCAL_SRC_FILES := \ libcharset/lib/localcharset.c \ lib/iconv.c \ lib/relocatable.cLOCAL_C_INCLUDES += \ $(LOCAL_PATH)/include \ $(LOCAL_PATH)/libcharset \ $(LOCAL_PATH)/lib \ $(LOCAL_PATH)/libcharset/include \ $(LOCAL_PATH)/srclibinclude $(BUILD_STATIC_LIBRARY)
4. 在E:\MyCocos\cocos2dx-workspace\hello\proj.android\jni工程的Android.mk里修改,加入这个lib和include目录(下面的路径要根据项目实际情况修改)
$(LOCAL_PATH)/../../cocos2d/iconv/include \$(LOCAL_PATH)/../../cocos2d/iconv/libcharset \$(LOCAL_PATH)/../../cocos2d/iconv/lib \$(LOCAL_PATH)/../../cocos2d/iconv/libcharset/include \$(LOCAL_PATH)/../../cocos2d/iconv/srclib \$(LOCAL_PATH)/../../cocos2d/iconv \LOCAL_WHOLE_STATIC_LIBRARIES += iconv_static$(call import-module,iconv)以下是我自己的Android.mk文件中的代码 以后如果版本变动可以参考这个代码来改
LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := cocos2dcpp_sharedLOCAL_MODULE_FILENAME := libcocos2dcppLOCAL_SRC_FILES := hellocpp/main.cpp \ ../../Classes/AppDelegate.cpp \ ../../Classes/HelloWorldScene.cppLOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes \$(LOCAL_PATH)/../../cocos2d/iconv/include \$(LOCAL_PATH)/../../cocos2d/iconv/libcharset \$(LOCAL_PATH)/../../cocos2d/iconv/lib \$(LOCAL_PATH)/../../cocos2d/iconv/libcharset/include \$(LOCAL_PATH)/../../cocos2d/iconv/srclib \$(LOCAL_PATH)/../../cocos2d/iconv \LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_staticLOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_staticLOCAL_WHOLE_STATIC_LIBRARIES += box2d_staticLOCAL_WHOLE_STATIC_LIBRARIES += iconv_staticinclude $(BUILD_SHARED_LIBRARY)$(call import-module,2d)$(call import-module,audio/android)$(call import-module,Box2D)$(call import-module,iconv)
5。网上很多教程都说到这里,但实际上,如果这个时候进行编译,问题还一大堆。
1)iconv.h不存在,在ivonv/include/有 iconv.h.in, iconv.h.build.in,就是没看到iconv.h
把iconv.h.in改名成iconv.h,发现编译很多错误
主要错误是类型不匹配,还有很多@符号。
因此需要进行修改。主要改法是不存在的改成存在的,@符号去掉
下面是我自己改完之后的iconv.h文件。编译OK.

copy完这3个文件
交叉编译时还有一个问题
config.h找不到
原因是库里面所以的config.h文件名都是config.h.in
在iocnv下面搜索config.h
将3个文件的.in去掉
交叉编译成功

原文给出的东西很有用 不过使用起来还是有一些错误 不过里面具体改了那些位置 他用蓝色标记注明了 还是很仔细的
