在对linux上的程序进行调试时，使用file program_name查看这个可执行文件的相关信息，可以看出可执行文件是32位程序。
由于系统的环境是64位的，默认不支持运行32位程序，所以需要安装32位的支持库以执行32位程序。
ar0nw@box: ~$ file program_name
program_name:
ELF 32-bit LSB executable,
Intel 80386, version 1 (SYSV),
dynamically linked,
Interpreter /lib/ld-linux.so.2,
for GNU/Linux 2.6.18,
BuildID[sha1]=96997aacd6ee7889b99dc156d83c9d205eb58092,
stripped
通过uname -a命令可以得知系统是64位的
所以使用sudo apt-getinstall ia32-libs下载32位的lib库
ar0nw@box:~$ sudo apt-get install lib32z1

之后32位的可执行程序即可在64位系统上执行。
