Note: This began in the thread "[CentOS] Probably a bad setup but which one?" but I don't want to hijack that thread. "tech" began with a similar problem, with the Perl "Hello World" script.

I can't get the "Hello World" program in the C++ book I began reading to work. Seems to compile without errors, but nothing on my CRT. Will try it again and start a thread >here... :-)

Let me guess...

you named it "test", right? Then when you run "test" "nothing" happens?

No. It is named Hello

two things:

1. there's already a program named test, which displays no output,

it merely has an exit status. 2. for a program in your current directory, run it with a preceding "./", e.g., "./test"--because "." is not in the path (and shouldn't be).

Fred: Thank you! #2 was dead on. :-)

[devel@dell2400 ~]$ ./a.out Hello, World! I am 8 Today! [devel@dell2400 ~]$

What I was lacking was the "./" in front of a.out the file produced when I compiled Hello.cpp :-)

I will continue reading the book now! :-) Lanny
