在使用gdb调试核心转储时指定glibc

我有一个程序在RHEL6.5上崩溃了，还有一个coredump文件

我想在RHEL6.4上调试它，但它有另一个版本的glibc。我将RHEL 6.5中的glibc.so.6放在lib/目录中，但无法将gdb设置为使用它：

[nskdvlp@srv2-csd-mong01 snmp_int]$ LD_LIBRARY_PATH=/u01/app/maa/snmp_int/lib gdb bin/snmp_int

(gdb) info sharedlibrary

Do you need "set solib-search-path" or "set sysroot"?

所以库可以很好地从lib加载/

我将RHEL 6.5中的glibc.so.6放在lib/目录中，但无法将gdb设置为使用它：

没有glibc.so.6这样的东西。你的意思是

libc.so.6

这远远不够：您需要生成核心的系统中的所有库和动态加载程序。看看这个你需要做什么
