cocos2d-x 3.0rc1 使用iconv库 解决UTF8乱码问题

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

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)#include "..\cocos2d\iconv\include\iconv.h"#endif#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)#include "..\cocos2d\external\win32-specific\icon\include\iconv.h"#endif#pragma comment(lib,"libiconv.lib")#include "string"using namespace std;//#ifndef A2U//#define A2Ustatic int code_convert(const char *from_charset, const char *to_charset, const char *inbuf, size_t inlen, char *outbuf, size_t outlen){    iconv_t cd;    const char *temp = inbuf;    const char **pin = &temp;    char **pout = &outbuf;    memset(outbuf,0,outlen);    cd = iconv_open(to_charset,from_charset);    if(cd==0) return -1;    if(iconv(cd,pin,&inlen,pout,&outlen)==-1) return -1;    iconv_close(cd);    return 0;}/*UTF8תΪGB2312*/static std::string u2a(const char *inbuf){    size_t inlen = strlen(inbuf);    char * outbuf = new char[inlen * 2 + 2];    std::string strRet;    if(code_convert("utf-8", "gb2312", inbuf, inlen, outbuf, inlen * 2 + 2) == 0)    {        strRet = outbuf;    }    delete [] outbuf;    return strRet;}/*GB2312תΪUTF8*/static std::string a2u(const char *inbuf){    size_t inlen = strlen(inbuf);    char * outbuf = new char[inlen * 2 + 2];    std::string strRet;    if(code_convert("gb2312", "utf-8", inbuf, inlen, outbuf, inlen * 2 + 2) == 0)    {        strRet = outbuf;    }    delete [] outbuf;    return strRet;}//#endif

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

cocos2d-x-3.0rc1 完美运行iocnv显示中文字符串

这里我就不截图了

这里也留个记录 供以后使用

参考了原文地址:http://blog.sina.com.cn/s/blog_a17b071c0101lm91.html

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

我的这个版本 代码就是直接copy
