Re: threads/2292: GDB process stops when debugging threaded program

Re: threads/2292: GDB process stops when debugging threaded program

[Oleg V. Zhylin]

Hi,

  As this issue came up again, I've checked with DDD folks, since DDD
steps through threads successfully. DDD does use gdb as debugging
engine, so clearly it does some configuraiton. We didn't figure out
what exactly DDD does, but the effect of it is that gdb locates
/lib/libthread_db.so.1. Thus it looks like my problem can be
re-formulated 

 How to make gdb locate libpthread_db library?

Take a look at the messages from the first message you posted about
the bug.  GDB already was finding libthread_db.so.1.  If it can't, it
will let you know loudly.

  Sorry for not looking this up myself, I definitely should have. It
seems like a lot of people use "pure" gdb (w/o DDD or other "shells")
for pthread projects debugging, but for some reason I experience
behavior described threads/2292 on every Linux box I have access to.
Looks like I'm missing something obvious, but I would be very grateful
if someone points out what is it exactly.
