Re: [ptp-dev] debug output question

If the SDM is running locally, you should see stdout on the Eclipse
console. It's not really possible to launch the SDM manually.

That explains it. thanks.
for the second point you made, how do you run SDM manually and
observe its output?

The target output stream is only supported for remote targets. A
remote target is when you use gdb to debug a remote system using
gdbserver. For normal uses of gdb, the target output stream
doesn't work, which is why we have to use pseudo terminals. It
would certainly simplify things to be able use target output
streams, but I don't think they have any plans to support it.

Greg -
... well, I didn't think, I just jump onto it.
thanks for the info, I will take a closer look at it.
A unrelated question on GDB/MI interface: suppose the target
program has a output stream, denoted by @, but as the following
interaction shows, "res = 6" stdio from sample program doesn't
have @ prefix ... why?
(gdb)
-exec-continue
^running
(gdb)
res = 6
*stopped,reason="exited-normally"
(gdb)
I also tried MI API to see if I get anything through target
callback, and again, nothing comes out of it ... am I missing
something here?
void
target_callback(char *str)
{
printf("target> %s\n", str);
}
int main()
sess = MISessionNew();
if (MISessionStartLocal(sess, "/home/fwang2/gdb/test") < 0) {
fprintf(stderr, "%s", MIGetErrorStr());
return 1;
}
MISessionRegisterTargetCallback(sess, target_callback);
cmd = MICommandNew("run", MIResultRecordDONE);
MICommandRegisterCallback(cmd, cmd_callback, sess);
sendcmd_wait(sess, cmd);
