GCC Problems!

Prthug996 · Sep 8, 2009

I'm a student completely new to C++ Programing, and my instructor knows nothing about Macs, so Im doing this on my own. I downloaded all of Xcode and wrote a program on it. Now Im trying to compile it. From what i can glean off the internet, I suppose to go to my terminal (which by the way, I didnt know existed, so you understand my knowledge level) and type something like;

gcc MP0temp.h

MP0temp.h being the program I wrote

Please Help!

PS Im very new to programing so the plainer the english the better

THANK YOU

If it is a C++ file, you should save it with .cc extension. eg. hello.cc

To run your first C++, just follow the following steps.
1) Open a text editor and write your code.
Eg.

Code:

#include <iostream>                                                                                                 
  2 int main()
  3  {
  4   std::cout << "Hello World!" << std::endl;
  5   return 0;
  6 }

Save it as <file>.cc Eg. hello.cc in your Desktop.

2) Open Terminal.app from /Applications/Utilities/ and type

Code:

cd Desktop

and hit enter.

3) To compile the file
g++ <file>.cc -o <file> eg.

Code:

g++ hello.cc -o hello

If your program is correct, this will create an executable file.

4) To execute the program
./<file> eg.

Code:

./hello

GCC - GNU Compiler Collection - Wikipedia, the free encyclopedia
