Could some body tell what I am doing wrong? I am trying to create a
simple vpi program.
the procedure I use is as follows
1)make
2)cp hello.vpi  /usr/lib/ivl/
3)chmod a-x /usr/lib/ivl/hello.vpi  // did this to have same permissions
as system.vpi
4)iverilog -mhello hello_test.v
5)./a.out
/home/stephen/geda2/hello.vpi/hello: Unable to link module
$hello: This task not defined by any modules. I cannot compile it.
./a.out: Program not runnable, 1 errors.

Is there some way to tell iverlog to look in the current directory for
modules ?
