Probably.  GDB will not debug threads without this (and an unstripped
libpthread.so).

No and no as far as I know.  I don't know if there is a thread
debugging package for FreeBSD at all.

GDB and Thread Problems

[dyadav]

Hi
     I am using GDB 5.2, on i386-unknown-freebsd4.2 .

      I am trying to debug a thread program ( Use PThread Library).
but i did not any output in info thread. What is the problem.

(gdb) info threads
(gdb) thread
[Current thread is 0 (process 20038)]
(gdb) thread 1
Thread ID 1 not known.
(gdb)

Is it due to as i do not have the libthread_db.so.1 library.
       #define LIBTHREAD_DB_SO "libthread_db.so.1"

Please help

Thanks & Regards
Deepak
