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
CC=/usr/local/arm-linux/bin/arm-linux-gcc
frank@ruhe:/arbeit/gdbserver$
../gdb+dejagnu-20030716/gdb/gdbserver/configure

Ok, then I start gdbserver and connect with gdb.

nothing about the thread. What can I do?

Frank,
Do you need to build gdb as a cross-gdb?
I had to build gdb twice. Once for the ARM target (for gdbserver). And again
for a gdb that runs on my x86 host but understands arm binaries.
Here is how I built:
tar xzf gdb-5.3-tar.gz
mkdir build-i686-to-arm
mkdir build-arm
cd build-i686-to-arm
../gdb-5.3/configure --host=i686-pc-linux-gnu \
--target=arm-linux \
--build=i686-pc-linux-gnu
make
cd ../build-arm
HOSTCC=gcc CC='arm-linux-gcc' CFLAGS='-msoft-float' \
../gdb-5.3/configure --host=arm-linux \
--target=arm-linux \
--build=i686-pc-linux-gnu
make

do think it is a build problem? Because normal debugging works. Only the
threads are missing.

The only reason I asked was because you didn't indicate anything about your
gdb build configuration, only your gdbserver config.
When you start gdb it will tell you what --host and --target is.
Also, before building gdbserver, you might need to apply the patch at:
http://sources.redhat.com/ml/gdb/2003-06/msg00535.html
