使用gdb看core的问题
来源: 互联网 发布时间：2015-10-25
本文导语: 我在solaris下用gdb -c core查看函数栈. 但函数名都是?: --- # gdb -c 94048.001.866.core GNU gdb 6.0 Copyright 2003 Free Software Foundation, Inc. GDB is free software, covered by the GNU General Public License, and you are welcome to change it ...

do_attach: couldn't open /proc file for process 94048
Core was generated by `./kfcm120'.
Program terminated with signal 11, Segmentation fault.

(gdb) where

#2 0xff115550 in ?? ()

这样的问题, 在别的平台也有类似的, 请问如何看到函数名?
thx

dbx yourprogram core
|
这个没办法，函数的符号已经被strip掉了，这样的话是没办法看得……
|
编译的时候加-g 选项，另外把该文件和源代码放在一个目录
|
不要使用-O优化选项
|
把这个core拷到你的编译的可执行文件同一目录下
然后gdb -c core文件名 可执行文件名
应该可以(linux下面)
