gdb works with egcs?

gdb works with egcs?

[The Red Fox]

I was wondering if gdb version 4.16 will work fully with object code
produed by egcs.

I have a situation where there is a static library compiled with egcs
using the -g flag. This library is then linked with an executable.
When debugging the executable, the debugger produces 'incomplete type'
for types defined in the library but not for types defined in the object
files that make up the executable itself.

Does ld need any special flags to make this work?

Ta,
Ben

Depends on your target.

gdb-4.16 doesn't understand dwarf2, which egcs now uses on some
systems.  gdb-4.17 will understand dwarf2.

dwarf2 is the default under Linux, correct?  Any word on when
gdb-4.17 will be ready?  I'm just now about to start the
debugging phase of a project, and am wondering if I ought to
go ahead and rebuild egcs to use some other format, or just wait
for gdb-4.17.

stabs is the default for Linux.

Soon.  I think they're in beta testing right now.

There might be some Linux where they made that the default, but I'd
be surprised.

We're supposed to branch the sources today.  (No, wait, I still have
one more checkin to do! :-) )  There will be snapshots for the adventurous,
and the release should be within a couple weeks, if pre-release testing
goes OK.

Will it support Linux/Alpha, which 980122 gdb doesn't?

That code was checked in today.

And Linux/PPC (glibc-2.0.91)? For core files I get "Can't fetch registers"
and executables can't be run.
