64位的linux系统运行32位程序

执行apt-get install ia32-libs的时候提示：bash: ./test: cannot execute binary file，应该是内核中没有编译与32位的兼容所致。

Executable file formats / Emulations

[*] Kernel support for ELF binaries
[ ] Write ELF core dumps with partial segments
<*> Kernel support for MISC binaries
[*] IA32 Emulation
IA32 a.out support

解决办法是编译进上面的模块即可。
