cpp on jGRASP doesn't work

[dalde7]

Hi,
I have installed jGRASP ON MY Linux 14.04 and I compile a hello_world.cpp and it is ok.
When I can run the hello_world it doesn't run and there is this error message:
----jGRASP exec: /home/daniele/Scrivania/jgrasp/examples/test_cpp
----jGRASP wedge: could not execute /home/daniele/Scrivania/jgrasp/examples/test_cpp
---- error number 2.
----
---- Target does not exist or is not on PATH.

----jGRASP: operation complete.

How can I resolve this issue?

Thank you all,
Daniele
