Question

最近我在下面的回溯中遇到了崩溃：

gdb) bt
#0  0x41447f48 in do_lookup_x () from /auto/andpkg/rep_cache/wr-x86/3.0FCS/sysroot/lib/ld-linux.so.2
#1  0x4144821f in _dl_lookup_symbol_x () from /auto/andpkg/rep_cache/wr-x86/3.0FCS/sysroot/lib/ld-linux.so.2

#7  0x415278ce in clone () from /auto/andpkg/rep_cache/wr-x86/3.0FCS/sysroot/lib/libc.so.6

我不知道如何从第4帧进行调试，所以我在前几帧开始使用googling do_lookup_x，_dl_lookup_symbol_x，发现它可能是ld-linux.so.2中的现有错误。所以我想得到这个.so文件的版本号。有人能帮我吗？谢谢！

来自 Linux from Scratch（LFS）主机系统要求文档，

ldd --version | head -n1 | cut -d" " -f2-  # glibc version

当我在现有机器上运行时，它会输出

$ ldd --version | head -n1 | cut -d" " -f2-
(Ubuntu EGLIBC 2.19-0ubuntu6.1) 2.19

如何查看ld-linux.so.2的版本？
