gdbserver ppc8xx

gdbserver ppc8xx

[Owen Green]

Hi all,

could anyone tell me where can I find a gdbserver that
works with mpc8xx processor? Where can I find sources
that compiles for 8xx?

I have already tried with mvista HHL2.0 Journeyman
edition but I got something like:
#gdbserver :7777 /bin/test
Process /bin/test created; pid = 48
getprotobyname:Sucess.
Exiting
#
What could be wrong? Any tip will be very appreciate.

Thanks in advance,

   Owen.

Well, use the one that came with HHL-2.0?

gdb-5.1 sources?

What do you think getprotobyname() does? [Hint: man getprotobyname  -
pay  special  attention  to  the  FILES section]. Hint2: There may be
other  networ  related  files  missing  on  your  system,  too,  like
/etc/services, or /lib/libnss_*

just copy /etc/protocols from whatever distro you like. Bye!

This did not work, I got the getprotobyname: Sucess,
what means my /etc/protocols have the entry for tcp.
Thanks anyway.

Did you try using strace? This can give you info about why gdbserver quits.

I also had a problem with gdbserver and this is the way I solved it...

if you are ultra-lazy and like bad code just edit remote-utils.c and
hardocde protocol number for TCP .... shouldn't chage shortly I guess ;-).

NSS is a hassle with embedded systems since is far too general .... even
busybox bypasses it ;-)

Bye!

Thank you all guys for the tips,
gdbserver was not working because linbss_files.so.2
was not present on my  system /lib.
By the way, why this was not shown when I typed:
readelf gdbserver -d ?

Thanks in advance,

Owen.

libnss* is dlopened by glibc.
