Re: Enable Support for Dwarf 1, with Gnu Extension

Hi,

Many thanks!
I've just compiled gdb 6.6, with insight, and see symbol but
some time got:
ptype a
<incomplete type>
or gdb seem to have difficult in determine next address (so
put breakpoint in wrong place so program many time go
running...)

Have you ever heard about a fix on this?
Some link to have info?
(ok: is much simpler work with dwarf2, but seem we have pb
with C++ binding of newer version of diab)
Have a good day

Sorry, I don't know.  These are probably specific problems
between GDB
and the debug info generated by Diab.

Only guessing, but you might try "gdb --readnow"
to force all 
the debugging info to be scanned at the start.  Might at
least
resolve the incomplete types.

That's unfortunate, since dwarf1 is quite old and
unsupported.
