我已经建立了使用LSB SDK测试程序ELF(注意,我的问题是不特定于LSB):我怎样才能找到不符合ELF的依赖关系?
$ /opt/lsb/bin/lsbcc tst.c
$ ls -l a.out
-rwxr-xr-x 1 math math 10791 2009-10-13 20:13 a.out
$ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped
但我无法启动它(是的,我向你保证文件是在目录 ...):
$ ./a.out
bash: ./a.out: No such file or directory
$ uname -a
Linux math 2.6.28-15-generiC#52-Ubuntu SMP Wed Sep 9 10:48:52 UTC 2009 x86_64 GNU/Linux
我觉得这是一个ELF依赖未履行,但我不知道如何找到它。是否有类似于ldd的工具可用于找到缺失的链接?
我不认为这是关系到2.6.15/2.6.28-15区别,因为LSB编译器工作:
$ file /opt/lsb/bin/lsbcc
/opt/lsb/bin/lsbcc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped
以防万一,这里是一个ELF的动态部分.out:

就是这样,我没有系统上的LSB解释器(/lib64/ld-lsb-x86-64.so.3)。事实上,我不知道我需要安装一个LSB特定解释器...... 有趣的是,LSB SDK中的二进制文件不符合LSB标准。 – math 2009-10-13 21:17:39
