cocos2dx 交叉编译 iconv库 protobuf库
cocos2dx提供三方的iconv来转化字符问题，交叉编译到android的时候，需要引入iconv的module，下载iconv, https://dl.dropbox.com/u/99895284/iconv.zip 解压到cocos2d根目录 ，编写mk：
proto作为游戏中的传输协议一部分是相当的有用（注意将mk，config.h放在同一目录）。版本2.5.0

编译成功运行
附上两个iconv的基本用法
//icove
int Kit::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;
}
/*UTF8 To GB2312*/
string Kit:: utf2gb( const char *inbuf )
{
size_t inlen = strlen( inbuf );
char * outbuf = new char[inlen * 2 + 2];
string strRet;
if(code_convert( "utf-8", "gb2312", inbuf, inlen, outbuf, inlen * 2 + 2 ) == 0)
{
strRet = outbuf;
}
delete[] outbuf;
return strRet;
}
string Kit:: gb2utf8( const char *inbuf )
{
size_t inlen = strlen( inbuf );
char * outbuf = new char[inlen * 2 + 2];
string strRet;
if(code_convert( "gb2312", "utf-8", inbuf, inlen, outbuf, inlen * 2 + 2 ) == 0)
{
strRet = outbuf;
}
delete[] outbuf;
outbuf = NULL;
return strRet;
}
注意修改iconv中.h ;.c中函数形参，否则编译不过
const char *from_charset, const char *to_charset, const char *inbuf, size_t inlen, char *outbuf, size_t outlen
由于NDK的变更，针对protobuf的编译config.h存在一定的变化 编译android 和IOS 等平台调整：
