Problem debugging a multi threaded program using gdb
I am debugging a multi-threaded program remotely on the target from another host, using 'gdbserver' on the target and 'gdb' on the host. I do the following:
target# gdbserver localhost:4567 ./my_prog
Process ./my_prog created; pid = 934
Listening on port 4567
host# arm-none-linux-gnueabi-gdb /home/asabat/targetfs/home/my_prog
(gdb) set sysroot /home/asabat/targetfs/
(gdb) set solib-search-path /home/asabat/targetfs/lib/
(gdb) target remote 10.101.24.118:4567
Remote debugging using 10.101.24.77:4567
(gdb) continue
When I stop it using a breakpoint and check the thread details using the command 'info threads', it shows only one thread. However, there are three threads running on the target for this program being debugged.
host#
(gdb) info threads

Previously I have done debugging of multi threaded programs using gdb and it used to work fine. I don't have any clue what I am missing here. I went through the gdb manual and couldn't find anything related.

Reason: wrong title line
