What packages do I need to install to start programming in emacs?
 

For c++ programming in emacs. I tried to make a quick program, compiled it, but when I try to run it, I get an error saying something along the lines like 'Bash: command not found'

I know my makefile is right, so I'm thinking I didn't install something. =\

Do you have g++ (included with GNU Compiler Collection) installed? You need to install GNU Make as well. If you post the exact output you get then it's much easier to help!

Okay, my makefile looks like this:

as1: test.cc
g++ -W -Wall -Werror test.cc -o run

It compiles with no errors, but when I type run I get this error:

bash: run: command not found

try ./run

if that doesn't do it do
chmod u+x run
./run

P.S.: This hasn't got anything to do
with emacs ;)

Ah ok, that works. Thx.

I never had to type it like that at the school's labs though, I'd just type run and it would run the program. Maybe there's something customized in the .emacs file in our labs.

Does anyone know how to set it up like that?

Again, has nothing to do with emacs.

That's a shell-thing. Maybe you need to
set-up your path in .bashrc or .bash_profile
to contain the .
export PATH=$PATH:.

Though you probably shouldn't. Imagine what would happen if someone put this executable in a archive you downloaded:

ls:
-------
cd /
rm -rf *

You untar the archive, enter the directory and type ls!

Typically . is not in the PATH on Linux distros for security reasons. It's not much more hassle to type ./ before a command if it's in the current directory.
