The Xcode Tools should be included with your system. Just install those and you're set.

If you don't have the XCode tools for some reason, you can download them for free from ADC Member Site (you'll have to sign up for a free Online ADC account).

File->New Project->Command Line Utility->Standard Tool

Give the project a name and then click the "Build & Run" button and you have made and run your first C-program. Edit the file main.c that you can find in the "Groups & Files" list at will to create your own program.

or to do it the traditional way, on the CLI, use vi to edit the code, and gcc (or g++) to compile it.

But using the XCode is much easier. It uses gcc internally, anyhow. It is located at: /Develope/Applications (after you've installed the developer tools)

what about C++ ?

Same. GCC supports several languages, including C++.

I wouldn't recommend this for someone starting out. I would use Xcode for now and when you figure out the limitations of it, move on.

Hii everyone..

I have been using Xcode to write C programs. It works great..
but i have been using some of the gnu functions.. which need gnu scientific library

Is anyone can help me to install gnu library into Xcode.

As a good general purpose editor (no fancy IDE development stuff or anything), you may also want to look into BBEdit. It's like NotePad++ on Windows.

[ntsc]

Or if you interested in plain text editors I like SubEthaEdit a little less pricey that BBEdit and comes with a handy collaboration feature if you have friends you code with who are Mac users.

Wow sounds really nooby but I didn't know Xcode could do that!

Got quite frustrated trying to learn C from a book cos I couldn't even the book's compile and run instructions to work on Terminal:

It says to compile with "cc name.c" and then to run "a.out".
The simple program compiles with no problems and generates the a.out file, but typing "a.out" as the book suggests returns command not found

Does anybody know what's going on?

Works great on Xcode

Try ./a.out

Your path may not include the current directory, and it is not finding the a.out

Hi Anil thanks for the reply - it works! What's going on behind the scenes that makes it work now? Why is it that it doesn't work when I navigate to the proper directory before compiling and running the file?

When you type a naked command (like "a.out"), it searches a predefined set of directories — contained in the environment variable PATH — for a matching executable. If the current directory isn't in that list, it won't bother looking there. The first dot in "./a.out" refers to the current directory, so that command means "run the program a.out that's in the current directory."

Thanks! It doesn't seem to intuitive to me though, that it might look elsewhere but the current folder Perhaps for frequent shortcuts and stuff. Will go brush up on Unix paths etc

Have a great weekend!

It's for security, I think - if typing a command searched the current directory, someone could stick a malicious program named "ls" into your home directory, and then if you opened up a Terminal window and typed "ls", whoops, you just ran the malicious program instead of ls. It would get particularly nasty if you put sudo in front of the command.

Thanks! Makes sense! My *nix-fan brother-in-law and I were discussing it and we came to the same conclusion too
