[Buildroot] gdb snapshot

[Sven Neumann]

Hi,

as I am having problems with gdb 6.8 on our ARM platform, I thought I'd
give the gdb snapshot a try and selected it in the buildroot menu. But
this fails as the patches in toolchain/gdb/snapshot seem to be targetted
at a particular snapshot (gdb-6.3.50.20050915). Does this work for
anyone else? Can this possibly work?

Maybe instead of using the the gdb.tar.bz2 symbolic link, we could
refer to a precise version of the gdb snapshot, so that the patches
have a chance to work.

The patches in snapshot/ haven't been updated since 2006, so I would
say that this part is unmaintained, which means that nobody uses it and
we can probably drop it.

What problems are you having with 6.8 exactly?

Ok, thanks for looking into this.

Perhaps someone can help me with the gdb problem I am facing. Whenever I
try to debug a program on the target platform (ARM EABI aapcs-linux),
the debugger gets a SIGCHLD signal and stops:

(gdb) r
Starting program: /hello 
Hello world

[1]+  Stopped(SIGCHLD)        gdb hello


Is there anything special I need to do to run gdb on the ARM platform?

Strange, it has atleast worked in the past. Do you have the same
problem with gdbserver?

Yes, exactly the same problem.
