Suppose that I have to run an application on machine 1.
Suppose also that this machine doesn’t have any screen.
How can run pdb on machine 2 to debug the software running on machine 1.
Thanks Alain.

You need to run pdebug on the remote machine
$ pdebug 8000 &
and then in the gdb prompt connect to it
(gdb) target qnx remote_host:8000
Just to clarify, thats
target qnx target_board_ip_addr:8000 - i.e. target qnx 10.23.3.10:8000
I was trying to use remote as an option (as it is one!) as well as qnx.

Aha, that’s your problem then.

Hi Colin,
I’m in the process of converting over from using codewarrior on the PC to
using RTP for development (we’ve talked about this in the past I think with
whats occurring/not with CW).
Forgive my ignorance here but I’ve couple of noddy questions on the
subject:
I presume then that for my target platform I will want to swap over the
C/C++ libraries (gnu rather than metrowerks) etc.
Anything else fundamental changed as far as image files is concerned
between Neutrino 2.0 and RTP)?
I will now be developing on a host machine with RTP and running code and
debugging it over the ether using ddd ( my target board has in house cards
attached which I can’t test on the host). Whats the best way to do this
then? Do I build the code and then transfer the executable to the target
manually before running ddd? If so how do I kick ddd off - how do I specify
what executable its debugging bearing in mind that the source is on the
host? Do I just run ddd ‘./progname’ and hope that the executable on the
target is the same or is there a kind of upload facility? As I say please
forgive my ignorance - this is new stuff to me.
Regards
Jim

Yes. Note that we will be moving to the Dinkum C/C++ libs fairly soon,
which will give you another (non GPL) C++ lib alternative.

The type of compression used to compress the image changed to a non GPL
algorithm, so your mkifs and startup must match, but if you are building
your image on the RTP all should be fine.

Download your files to the target machine.
On your target:
$ export LD_LIBRARY_PATH=path_to_where_your_shared_objects_are_on_target
$ pdebug 8000 &
run ddd (no args)
Then in the gdb console:
(gdb) target qnx remote_ip:8000
(gdb) set qnxinheritenv 1
(gdb) set solib-search-path path_to_where_your_shared_objects_are_on_host
(gdb) sym path_to_program_on_host
(gdb) run path_to_program_on_target args
(gdb) break main
(gdb) cont

Download your files to the target machine.
On your target:
$ export LD_LIBRARY_PATH=path_to_where_your_shared_objects_are_on_target
$ pdebug 8000 &run ddd (no args)
Then in the gdb console:
connect
(gdb) target qnx remote_ip:8000
make sure target environment is used, not host environment
(gdb) set qnxinheritenv 1
tell gdb where to find symbols for shared objects
(gdb) set solib-search-path path_to_where_your_shared_objects_are_on_host
load symbols of executable
(gdb) sym path_to_program_on_host
launch program on remote target
(gdb) run path_to_program_on_target args
set breakpoint at main
(gdb) break main
set program running
(gdb) cont
