Re: multi-thread remote debugging i386-linux target (NEED HELP)

[Peter Choi <peter_tkchoi@yahoo.com>]

Hi,

  Looking at the map of gdbserver :

00843000-00858000 r-xp 00000000 03:02 755706    
/lib/ld-2.3.2.so
00858000-00859000 rw-p 00015000 03:02 755706    
/lib/ld-2.3.2.so
0085b000-0098e000 r-xp 00000000 03:02 985716    
/lib/tls/libc-2.3.2.so
0098e000-00991000 rw-p 00132000 03:02 985716    
/lib/tls/libc-2.3.2.so
00991000-00994000 rw-p 00000000 00:00 0
00996000-0099b000 r-xp 00000000 03:02 983102    
/lib/tls/libthread_db-1.0.so
0099b000-0099c000 rw-p 00004000 03:02 983102    
/lib/tls/libthread_db-1.0.so
08048000-08053000 r-xp 00000000 03:05 412011    
/home/pchoi/work/tools/i386-linux/bin/gdbserver
08053000-08054000 rw-p 0000b000 03:05 412011    
/home/pchoi/work/tools/i386-linux/bin/gdbserver
08054000-08056000 rw-p 00000000 00:00 0
0964e000-0966f000 rw-p 00000000 00:00 0
bf56e000-bf56f000 rw-p 00000000 00:00 0
bff7a000-c0000000 rw-p fffdc000 00:00 0

  It seems it can load the libthread_db. So the path
should be correct.

  But I still can't see other threads being created.
So, what could be the possible problem???

  Pls advise. Thank you for your attention.

Regards.
Peter Choi
