我交叉编译的方法如下 /configure  --host=arm-linux --enable-shared  --enable-static --prefix=/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/

然后写的测试例子如下:

#include

int code_convert(char *from_charset,char *to_charset,char *inbuf,int inlen,char *outbuf,int outlen)

{

iconv_t cd;

char **pin = &inbuf;

char **pout = &outbuf;

cd = iconv_open(to_charset,from_charset);

if (cd==0) return -1;

memset(outbuf,0,outlen);

if (iconv(cd,pin,&inlen,pout,&outlen)==-1)

return -1;

iconv_close(cd);

return 0;

}

int u2g(char *inbuf,int inlen,char *outbuf,int outlen)   //UNICODE码转为GB2312码

{

return code_convert("utf-8","gb2312",inbuf,inlen,outbuf,outlen);

}

int g2u(char *inbuf,size_t inlen,char *outbuf,size_t outlen)  //GB2312码转为UNICODE码

{

return code_convert("gb2312","utf-8",inbuf,inlen,outbuf,outlen);

}

int main()

{

unsigned char in_utf8[] = {0x20,0xe8,0xbf,0x99,0xe6,0x98,0xaf,0xe4,0xb8,0x80,0xe4,0xb8,0xaa,0x69,0x63,0x6f,0x6e,0x76,0xe7,0x9a,0x84,0xe6,0xb5,0x8b,0xe8,0xaf,0x95,0xe4,0xbe,0x8b,0xe7,0xa8,0x8b,0xef,0xbc,0x9a,0xa,0xe2,0x80,0x9c,0xe7,0xba,0xb5,0xe6,0xb5,0xb7,0xe6,0x9d,0xaf,0xe2,0x80,0x9d,0xe4,0xb8,0x9c,0xe5,0x8d,0x97,0xe5,0xa4,0xa7,0xe5,0xad,0xa6,0xe7,0xac,0xac,0xe4,0xb8,0x89,0xe5,0xb1,0x8a,0xe5,0xb5,0x8c,0xe5,0x85,0xa5,0xe5,0xbc,0x8f,0xe7,0xb3,0xbb,0xe7,0xbb,0x9f,0xe8,0xae,0xbe,0xe8,0xae,0xa1,0xe9,0x82,0x80,0xe8,0xaf,0xb7,0xe8,0xb5,0x9b};    //UTF-8编码

char out[100];

int rc;

rc = u2g(in_utf8,strlen(in_utf8),out,100);

printf("ddddddd%s\n",out);

char uOut[100],inG[100];

char *p="utf-8编码的问题\n";

printf("pppp:%s\n",p);

sprintf(inG,"%s",p);

rc=g2u(inG,16,uOut,100);

printf("utf-8 %s\n",uOut);

}

编译方法如下: arm-linux-gcc -o word wordtest.c -libconv

报如下错误:

/opt/FriendlyARM/toolschain/4.5.1/lib/gcc/arm-none-linux-gnueabi/4.5.1/../../../../arm-none-linux-gnueabi/bin/ld: cannot find -libconv

用arm-linux-gcc -o word wordtest.c -Llibconv

却出现： [attachment=4362]
