Hi, PTP developpers

A simple problem but I have no clue. I cannot start debugging a simple test program in local while it can run both in shell and in eclipse ptp.

The console ouput for debugging is this:

#PTP job_id=8322

[mpiexec@lqc] Sending Ctrl-C to processes as requested

[mpiexec@lqc] Press Ctrl-C again to force abort

Could not attach to process. If your uid matches the uid of the target

process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try

again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf

ptrace: �\215�\205\201许�\232\204�\223\215�\234.

/home/lq/Cworkspace/testmshadow/8322: 没�\234\211�\202�个�\226\207件�\210\226�\233��\225.

The program is not being run.

...

settings are these:

OS: Ubuntu 12.04

platform: Eclipse for Parallel Application Developers Luna(4.4.1)

MPI: mvapich2 (base on mpich2 3.1.2,almost the same)

target system configuration: Generic MPICH2 Interactive

session address: default or localhost or my ip address, both cannot work
