mips64 gdb problem

[Maxim Osipov]

Hello,

I have a problem trying to debug 64-bit mips binary with gdb-6.3. It
fails with the following message:

/home # gdb 64test

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)

Sections of this binary looks like the following:

GCC generates a wacky 64-bit format, otherwise only used on IRIX.  I
think this is a bug in GCC.  GDB could be adapted to generally sort of
cope with it, but not completely - there's some ambiguity.

Is there known solution for it? Couldn't find any on google.

I know OpenBSD/mips64 works fine, which uses GCC 3.3.5, so there must
be something wrong in the mips64-linux-gnu GCC config.that can tweaked
such that it uses the proper 64-bit DWARF debugging stuff.
Alternatively you might want to check out GCC 4.0.

You didn't say what your host is.  It looks like mingw32; gdb 6.3 did
not support mingw32.  Hopefully the next release will.

Get yourself a real operating system ;-).  Or pretend you have one by
installing Cygwin.

Oh how constructive. Why don't you learn to quote?

Evandro:

The Mingw project has patched sources for 6.3 available  at

http://prdownloads.sf.net/mingw/gdb-6.3-1.tar.bz2?download

you may have better luck compiling for a windows host with that

gdb error

[Tom Kazakoff]

I have built gdb as a i586-pc-cygwin x m68k-coff-bdm debugger.
When I type: target at the gdb> prompt, one of the options is cpu32bug, 
which is the debugger my board runs at startup, and that I can talk to via
HyperTerminal. The gdb is running under a cygwin bash shell on NT, service
pack 6a.

I type; target cpu32bug COM1 <ret>

I then get 4 errors that are;
get_tty_state failed: Not a typewriter
get_tty_state failed: Not a typewriter
get_tty_state failed: Not a typewriter
get_tty_state failed: Not a typewriter

Sometimes I just get one error which is:
Not a typewriter

and sometimes the system crashes, with a 
segmentation error.

I have used the   set remotebaud 9600
			set serial 1
commands prior to issuing the target cmd.

I cannot find any meaningful information in the documentation about
this.

Do you have any idea what this error means and how to fix it ????????
