Usually, under Unixes such as Linux, when people try to run a program called "test" nothing happens, since they're running a Unix utility rather than their program. But if you're getting some of the output from your program, I guess that's not the problem. There has been some discussion here in the past about problems with tasking with the GNAT being distributed with some versions of Linux.

If in doubt, always do a ./test if the executable is in your current directory (this is a good general practice anyway, to avoid trojan horses). If the executable is in another directory, then you can also invoke by pathname, starting from '/'. Without qualifying the name of the executable, Jeffrey is right: you usually end up invoking the shell test command (builtin, or otherwise). -- Warren W.
