I am sure compiling and linking has no problem. Would you please put it
more concretely, how to have Debug options turned on?

Thanks, but it seems a little complicated to me

BTW, I found that running by "mpiexec -n 1 spawn1.exe" here has no
effect, even the MTest_Init( &argc, &argv ); fails. but if I just run
"spawn1.exe" the MTest_Init( &argc, &argv ); run without any problem
