linux使用iconv库问题，急急急！！！

有A/B两台机器，都是linux，redhat
我写了一个简单的程序，main.cpp，引用<iconv.h>



#include <iostream>

#include <map>

#include <iconv.h>

 

using namespace std;

 

char* utf8_to_gbk(char *inbuf)

{

        iconv_t cd = iconv_open("GBK", "UTF-8");

            size_t inlen = 1500;

                size_t outlen = inlen * 4;

                    char *outbuf = (char*)malloc(outlen);

                        bzero(outbuf, outlen);

                            char *in = inbuf;

                                char *out = outbuf;

                                    iconv(cd, &in, (size_t*)&inlen, &out, &outlen);

                                        iconv_close(cd);

                                            return outbuf;

}

 

int gbk_to_utf8(char *inbuf, char *outbuf)

{

        iconv_t cd = iconv_open("UTF-8", "GBK");

            size_t inlen = 1500;

                size_t outlen = inlen;

                    bzero(outbuf, outlen);

                        char *in = inbuf;

                            char *out = outbuf;

                                iconv(cd, &in, (size_t*)&inlen, &out, &outlen);

                                    iconv_close(cd); 

                                        return 0;

}   

 

int main()

{

    std::map<int, int> imap;

    cout << imap[1] << endl;

    imap[1] = 1;

    cout << imap[1] << endl;

 

    return 0;

}

在A机器上直接g++ main.cpp -o test 能编译
在B机器上g++ main.cpp -o test 编译报：: undefined reference to `libiconv_open'

目的想让B机器也能直接g++ main.cpp -o test编译过，而不需要改变A机器的环境配置
查了一下，iconv是glibc里的，难道是A/B机器的glibc版本问题？

求大神们指点如何解决？还需要什么信息？
