gdbserver on arm and multithreading again

[unknown <tmp1@nerdig.de>]

Hi

I read many postings about this, but I cannot get it working. :(

My Testprogram:
--
#include <stdio.h>
#include <pthread.h>
#include <sched.h>

void * Thread1( void * p )
{
  char * ptr = 0;
  *ptr = 0; // Make Segfault in Thread
  return NULL;
}


int main( int argc, char ** argv )
{
  pthread_t pid;
  pthread_create( &pid, NULL, Thread1, NULL );
  pthread_join( pid, NULL );
  return 0;
}

-----------------------------------------------------------

I built gdbserver like this:

frank@ruhe:/arbeit/gdbserver$ export

frank@ruhe:file gdbserver
gdbserver: ELF 32-bit LSB executable, ARM, version 1 (ARM), for
GNU/Linux 2.0.0, dynamically linked (uses shared libs), not stripped

-------------------------------------------------------

Ok, then I start gdbserver and connect with gdb.

nothing about the thread. What can I do?

Thanks for any answer
