不同Linux系统下同一个可执行文件执行问题

[fjpqzm]

==>问题
把A Linux系统上的一个执行文件mytest拷贝B Linux系统上，chmod a+x mytest后执行出现如下问题：
bash: ./mytest: 没有那个文件或目录

==>
用file和ojdump查看mytest如下：
>file mytest
mytest: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped


>objdump -h mytest
mytest： 文件格式 elf32-i386

为了一步做比较，我用file和objdump查看B系统上的一个可执行文件new_mytest如下：
>file new_mytest

>objdump -f new_mytest

new_mytest： 文件格式 elf32-i386
体系结构：i386，标志 0x00000112：
EXEC_P, HAS_SYMS, D_PAGED
起始地址 0x0804a4b0

比较两个可执行文件的结果，看不出为什么会出现这个问题。各位CSDN的大虾们帮忙看看是什么问题导致mytest执行文件不能执行？

[dai_weitao]

mytest: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped

new_mytest: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.4, dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped

这能说明什么? 为什么一个有kernel版本而另一个没有?

[cceczjxy]

ldd: /lib/ld-linux.so.2 exited with unknown exit code (139)

这样就是缺少共享库了.
正常的
[root@shwhg test]# ldd a.out
libc.so.6 => /lib/tls/libc.so.6 (0x4eb26000)
/lib/ld-linux.so.2 (0x4eb0d000)


静态编译的
[root@shwhg test]# ldd a.out
not a dynamic executable


你在原来的机器上改成静态编译看看.

[k_f]

加个.sh后缀，用sh mytest.sh试试

[lurenfu]

导致不能执行的原因多半是动态库的问题
用ldd看看

[cceczjxy]

也可能是路径的问题,你用绝对路径执行一下.

[maoxianqu]

关注

[fjpqzm]

1.我这个是elf文件，不是sh脚本
2.用绝对路径也不行，还是出现没有那个文件或目录问题
3.用ldd查看结果如下
ldd: /lib/ld-linux.so.2 exited with unknown exit code (139)
好像有点眉目，可是我不知到是什么问题？

[fjpqzm]

我原来的机子坏了，没办法重新弄过

[fjpqzm]

虽然经过各位大虾们的建议，这个问题还是没有解决，但是还是谢谢大家！
