   Take a look at http://sourceware.cygnus.com/gdb/contribute.html , and
   let me know what you think.

Looks like it is hell of a lot more usable than the FSF gnats
database.

The ARM port of eCos, http://sourceware.cygnus.com/ecos , contains
gdb stubs which can be made to run on the SA-110 with a few minor
modifications.

This is perhaps not exactly what you asked for ..?

Hi,

I'm trying to set a breakpoint in a file that is indirectly
included in my project.  When I try to set a breakpoint
on it, the following message occurs:

No source file named MismatchedTokenException.cpp.

The file lives in a separate tree which contains various support
routines.  I've added to my path the location of the file, but
that didn't work.  

Any ideas??

TIA,
-Tennis

Jim,

the file that ultimatly needs to have this information is
gdb/CONTRIBUTE.  That is what gets shipped.

Perhaphs, renaming ``Development'' to ``Contributing'' would be
sufficient.

The numbering scheme I prefer has multiple layers. For each event type
that GDB handles in a generic way, there is a value of TARGET_WAITKIND_*
that is always preferred. For miscellaneous events that GDB doesn't know
how to handle specifically, you have TARGET_WAITKIND_SIGNALLED or
TARGET_WAITKIND_CPU_EXCEPTION, both of which activate a target-defined
auxiliary field that carries the signal/exception type. When this happens:

For unixy targets, you get TARGET_WAITKIND_SIGNALLED and a signal number.
For raw targets, you get TARGET_WAITKIND_CPU_EXCEPTION and a vector number
(or something like it -- on many RISC chips this is not a simple integer).

The reactionary position is:

It is not the job of the generic inferior event stuff to disambiguate
unixy signals like SIGTRAP. That is what unix tdep files are for.

The more reasonable position is:

As early as possible, I want a SIGTRAP to become a TARGET_WAITKIND_BREAKPOINT
so that above some layer I never have to think about SIGTRAP on any target,
except in the case of a spurious SIGTRAP that matches no breakpoint, which
should be treated like any other uncaught signal.

I have this problem on BeOS.
I can give you an fd_mask that will work.
Unfortunately, i had to disable the event loop based interface because
our select isn't good enough yet.

We don't have poll, neither.
