一 Win32环境配置

1 引入头文件

2 引入静态库：libiconv.lib

3 定义一个公用转码函数

#include "iconv.h"


bool iconv_convert(void *src, unsigned int src_len,char *src_charset, void *dest, unsigned int dest_len, char *dest_charset)
{
	const char *in;
	char *out,*dest_ptr;
	size_t in_left,out_left,mutant,converted;


	in_left=src_len;
	out_left=dest_len;
	in=(char *)src;
	out=dest_ptr=(char *)dest;


	iconv_t oConv=iconv_open(dest_charset,src_charset);
	if(oConv==(iconv_t)(-1))
	{
		CCLog("ERROR: unable to open libiconv.");
		return false;
	}


	mutant = iconv(oConv, &in, &in_left, &out, &out_left );
	iconv_close(oConv);
	if(mutant == (size_t)(-1))
	{
		CCLog("ERROR: unable to convert anything.");
		return false;
	}
	converted = dest_len - out_left;
	CCLog("to convert %u characters, %u mutanted , %u converted \n",src_len,mutant,converted);
	dest_ptr[converted]='\0';


	return true;
}

4 测试

void convertTest()
{
	char inStr[] = "Hello, 这是个测试程序";
	char outStr[1024];
	iconv_convert(&inStr, sizeof(inStr), "GBK", &outStr, sizeof(outStr), "UTF-8");
	CCLog("scr string:%s\n", inStr);
	CCLog("dst string:%s\n", outStr);
}

5 跨平台头文件包含设置

#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32
#include "iconv.h"
#elif CC_TARGET_PLATFORM == CC_PLATFORM_IOS
#include <iconv.h>
#elif CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
#include "icov/iconv.h"
#endif

二 为Android编译iconv

1 下载

2 编译

./configure --build=x86_64-pc-linux-gnu --host=arm-linux-eabi

切记此处不是./configure，不然到后面会报一大堆stdio.h里面的错。

make

make clean

3 拷贝头文件

4 配置

4.1 拷贝libiconv 到工程

将libiconv放置在cocos2d-x-2.1.4根目录下

4.2 编译配置 

在libiconv目录下新建一个Android.mk文件，内容如下：

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := iconv_static
LOCAL_MODULE_FILENAME := libiconv


LOCAL_CFLAGS :=   -Wno-multichar   -DAndroid   -DLIBDIR="c"   -DBUILDING_LIBICONV   -DIN_LIBRARY


LOCAL_SRC_FILES :=   libcharset/lib/localcharset.c   lib/iconv.c   lib/relocatable.c


LOCAL_C_INCLUDES +=   $(LOCAL_PATH)/include   $(LOCAL_PATH)/libcharset   $(LOCAL_PATH)/lib   $(LOCAL_PATH)/libcharset/include   $(LOCAL_PATH)/srclib
  
include $(BUILD_STATIC_LIBRARY)

4.3 修改项目的Android.mk

a 添加搜索路径

b 添加iconv_static

c 包含iconv子模块

三 常见错误

1 langinfo.h: No such file or directory

2 ‘c‘ undeclared
