Newbie error compiling program

Newbie error compiling program

[youKnowme]

I am using emacs to compile a simple 'hello world' program in c++ mode.

When I type the command to compile the source file I get this error message:

'cd ~/
make -k
make *** no input targets specified and no makefile found. Stop.
compilation exited abnormally with code 2 at (time / date).'

Can anyone tell me how to fix this problem please.?

Thanks in advance.

Instead of `make', give your own command there...like `g++ hello.cc'

Thank you, this fixed the problem. I have another related question. How do i
get emacs to know that a program that i want to execute is in my current
directory? At the moment, I have to keep typing ./ before the executable
name. How can I set it up to do this automatically?

Thanks.

The environment variable $PATH can contain the entry ".".

But I don't recommend to do this.  Imagine you do 

    cd /tmp
    ls -la

and some bad guy has written /tmp/ls which deletes your hard disk.

How about if you put the . at the end of the search path?

Then some funny bloke will write /tmp/mkae or /tmp/telent.

This is OK as a quick fix.

Once you get past "newbie", you'll want to learn "make".  It's the
best way to automatically build a real program with many classes.

At the "Compile command: make -k " prompt, type the name of the executable

(e.g. hello_world) before RET.  The make program should have a default rule
for building it from the C++ source file extension.
