A handler for the OS ABI "GNU/Linux"...

A handler for the OS ABI "GNU/Linux"...

[Peter Skvarka]

I have gdb connected to server at localhost:3333,
server is OpenOCD debugger connected through JTAG into target ARM9 board.

I have two questions:
1. Is possible to load symbols and do source-level debug with current gdb
version and code running on ARM9 
with embedded kernel 2.4.19 and application compiled with gcc 2.95.3 ? Is
not older compiler hurdle for contemporary gdb ?

2. When I trying to run my application from insight GUI, I meet this
warning:
"A handler for the OS ABI "GNU/Linux" is not built into this configuration
of GDB. 
Attempting to continue with the default settings."

What does it mean this error and how can Ito correct it ?

Regards !
Peter

No, it should be fine.  You can't use GDB to do Linux application level
debug over JTAG, though.  Use JTAG for the kernel and gdbserver for
the application.

You're debugging a Linux target.  Configure GDB for Linux when you
build it.

No.  You must run the gdbserver program, which is part of GDB, on your
target system in order to debug userspace applications.  You can't
use JTAG to do it; GDB doesn't support that.

JTAG will be fine for the kernel.
