how to execute a c++ file

[IsKall]

How do I execute a hello.cc file from the terminal?

It works perfectly from Anjuta but I want to learn to execute from the terminal too.

I tried all these:


gcc hello.cc
g++ hello.cc

gcc hello.o
g++ hello.o


but it doesn't show Hello World! (just a easy cout thing to see if the execution works in the terminal).

First, create a file (I'll call mine hello.cpp)


#include <iostream>

int main() {
std::cout << "Hello, world!" << std::endl;
}


Then compile with


g++ hello.cpp -o hello


Run the executable with


./hello

how do I compile multiple .cc and a .h files together?

[Lord Illidan]

You need makefiles for that. Google up some tutorials..I never made one myself.

okey, will look for that :)

A Makefile is the right choice for a project with multiple source files, you might even want to use autoconf and automake which will create the Makefile for you.
Although for quick testing this is overkill, just compile them like in the example above:

g++ -o hello hello.cpp world.cpp

Alternatively you can also compile the files separately and link them together as a last step:

g++ -c hello.cpp # produces hello.o
g++ -c world.cpp
g++ -o hello hello.o world.o

It's easier using the best IDE Code::Blocks (http://forums.codeblocks.org/index.php?board=20.0). ;)
