Loading dl-debug.c in gdb / Ubuntu 14.04.4 LTS

转自: https://stackoverflow.com/questions/36025694/loading-dl-debug-c-in-gdb-ubuntu-14-04-4-lts

 

==============================Question=============================

 

When I use

 

gdb xxx

 

, while loading, this is the result:

dl-debug.c:74: No such file or directory. 
dl-debug.c:74: No such file or directory. 
dl-debug.c:74: No such file or directory. 
dl-debug.c:74: No such file or directory. 
dl-debug.c:74: No such file or directory.

lots of it, how can I solve it?

I've searched this in the internet, but all the answers are not the resolution. Some might recommended that "apt-get source glibc" or "apt-get install libc-source", but NO HELP.

I've tried to

 

find /usr | grep dl-debug.c

 

, but, this file is not on my linux.

Any help?

I've solved this problem.

Firstly, use "apt-get install eglibc-source" to get the source file, while "glibc-source" is not a valid package. Secondly, locate your source file .tar.xz (mine is in /usr/src), uncompressed it. Finally, run gdb, and type "directory /usr/src/glibc-xxx(your location)/elf", and "dl-debug.c" is in this directory.

Also, adding "directory /usr/src/glibc-xxx(your location)/elf" in ~/.gdbinit might help u a lot.
