Linux exec not running

[sid_galt]

I just reinstalled Suse Linux 10.0 with GNome interface. I tried to test c++ with a hello world application. I compiled it like this


g++ -o hello hello.cpp


Although the compiler built the executable file, when I tried to run it from the shell using exec, it said


bash:exec:hello: hello not found

What's the problem?

Thank you for the help

just try
./hello
or whatever the filename is
--shawn

a.out is the output. you can rename it what ever you like, but immediately after compilation, it is called a.out... you might have to do a ./a.out if you do not have "the current directory" in your search path.

Normally you would be right, but not in this case. He used the '-o' flag which changed the output filename to 'hello'.

As for why this is not working, are you sure it compiled correctly? Did you check to make sure that a file called 'hello' was in fact created? Because the output is telling you that that file is not there.
