Question about TCP/IP stubs, gdb-5.2.1

Question about TCP/IP stubs, gdb-5.2.1

[Robert Bedichek]

The only TCP/IP stub I found was for Wince.  I need one for Linux.  Does
anyone have a pointer to a stub, the thing that runs on the target, or the
machine being debugged, that is closer to what I need than the Wince stub
included in 5.2.1?  (The architecture is x86)

Thanks in advance!

Are you talking about application level debugging?  If so, you want
gdbserver, which is included in the GDB release.  If you're talking
about kernel level debugging, then TCP/IP is generally considered
impractical from an interrupt context.

Thanks for the pointer to gdbserver, that might be the best starting
point.

What I want this for a connection to a full system simulator.  I
used to compile simulators directly with gdb, but this time I want them
separated.  There are seveal reasons, but one is that I want to be able to
have thousands of simulators running for days in an LSF-managed farm.  I
want to be able to connect to a simulator, do some debugging, and
disconnect, letting the simulator run some more.  This is like attaching
to processes with regular gdb.

So what I plan to do at this point, unless someone has an even better
suggestion, is to start with gdbserver, rip out the part that talks to a
Linux process, and make it so that it can be compiled with the simulator
and access the simulator data structures directly.

Thanks again!
