我在64位gentoo上运行32位代码时遇到困难，该程序非常简单:
#include <stdio.h>
main()
{
printf("Hello World");
}
我用
gcc -m32 -o hello32 hello.c编译了它。输出似乎正确:ozn@yeni2gen:~$ gcc -m32 -o hello32 hello.c
ozn@yeni2gen:~$ file hello32
hello32: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, not stripped
但是，当我尝试运行文件时，出现错误:
./hello32
bash: ./hello32: No such file or directory

最佳答案
好的，谢谢您的提示。显然，我的gentoo做错了。在gentoo论坛上进行了很多研究之后，并感谢这里的提示，我找到了一个解决方案:
(root)# ln -vs /lib32/ld-linux.so.2 /lib/ld-linux.so.2
给我这个提示的original discussion in the gentoo forums。
