gdb debugging threads help

[Teresa Rivas <teresa.rivas@cadenux.com>]

Hi,

I need to debug multi-threaded applications that runs on an arm platform
in my x86 platform but I can't make that gdb compile and build the
thread-db sources. This is the way I configured gdb:

./configure --host=i386-linux --program-prefix=arm-linux-
--target=arm-linux

and this is the way I configure gdbserver:

./configure --host=arm-linux --program-prefix=arm-linux-
--target=arm-linux

this are the libraries in the target and which paths I set in gdb using
set solib-absolute-prefix and set solib-search-path commands:

-rwxr-xr-x  1 trivas trivas   91306 2005-11-17 08:12

lrwxrwxrwx  1 trivas trivas      22 2005-11-17 08:12 libthread_db.so.0

lrwxrwxrwx  1 trivas trivas      22 2005-11-17 17:03 libthread_db.so.1
-> libthread_db-0.9.26.so

the problem is that I can't see the treads created when I am debugging
the application, only the main thread:

on the target:
# gdbserver :5234 simple
Process simple created; pid = 91
Listening on port 5234
Remote debugging from host 192.168.200.29
thread 1 created
thread 2 created
Glory, employees contents was always consistent

Child exited with retcode = 0

Child exited with status 0
GDBserver exiting


on the host:

Program exited normally.
(gdb)

and if I try a info shared it says "No shared libraries loaded at this
time"

I see there is a thread-db.o target on the gdb/Makefile file but I can't
configure gdb so it execute this thread-db.o target which I believe add
the gdb debbug thread support.

Have had somebody a similar problem or an idea that can help me?
