I can't run gdbserver, I've to run my own debug-server usually on the same machine
than gdb (not on the target in any case). Then I start sparc-elf-gdb with target
extended-remote host:xxxx. This allows gdb to download and run a program to the
target usign the my debug-server.

Am I right to suppose that Eclipse talks directely to gdb and the communication
channel between gtb and my debug-server is don't care ?

If so I've probably only to switch on "-gdb-set auto-solib-add on"  in gdb. (I can
verify it only tomorrow in the office).

Last two questions:
    - what is the GDB/MI protocol ?
    - does Eclipse starts gdb when a debug session is started or have I to start it
outside and Eclipse simple try to take the control over it ?

Thanks Joel
