解决方法：+++++++++++++ 在上面基础上，编译libiconv （静态库）
這似乎是NDK的BUG，在stdlib.h內有宣告出__ctype_get_mb_cur_max函數，但是卻沒有去實作它。如果出現這個問題，不建議直接修改NDK，要到libiconv目錄下，修改「libcharset/lib」目錄裡的「localcharset.c」檔案，在檔案最下面加上以下程式碼即可。
[root@localhost libiconv-1.14]# gedit /opt/cBPM-android/libiconv-1.14/libcharset/lib/localcharset.c
size_t __ctype_get_mb_cur_max(void){
return 1;
}
保存，重新编译libiconv （静态库）

U __ctype_get_mb_cur_max
