Re: [ptp-user] Problem using Debug mode

["Jerome Son Ni" <ishinot@xxxxxxxx>]

Hi Clement,

Thanks! Setting the machine's name seems to get the debugger running.
I tried to debug using the PTPSimulation template and it works fine, though it's odd that there's no output from the PTPSimulation program onto the console. Using Run displays all the program output.
On my program, however, it doesn't seem to break at the main( ) function. It shows the processors but no call stack is available. I had to kill it manually.
The source code path seems to be there with no duplicates. Below is the output:

++++++++++ ptp_orte_proxy: ------------------- gdb version: 6.400000
++++++++++ ptp_orte_proxy: ------------------- gdb version: 6.400000

Hi Jerome,

Are you running ptp on local machine? If not, you need to set
"SDM client host" on the machine you are running. The field is on
"Perferences" -> "PTP" -> "Debug" -> "SDM".

Regards,
Clement
