Xcode help

  1. Aug 26, 2008 #1
    So I took C and C++ classes in high school, and can remember most of it, but all of that was under Windows (devC++ to be exact). After switching to a mac in college I recently download Xcode and was a little intimidated with all the "developer tools". I don't really plan to use that stuff any time soon, but wanted a C++ compiler that runs native on macs. Anyways can I get some help on getting started and just compiling written programs. Like I said no help needed with the C++ just the enviroment. Thanks!

    If you've installed XCode, then XCode has already covertly installed GCC, which is the Mac OS X compiler. If you want to use GCC without bothering with XCode, just open a new window in Terminal and say

    gcc filename.c -o programname

    to compile filename.c, then say

    ./programname

    to run it.

    what is the difference between filename.c and programname.c?

    By default unix compilers generate an output executable called a.out (for historic reasons) rather than filename.exe on a dos machine.
    You can tell gcc what to call the output executable with the "-o name" command.
    When you get to more complicated programs you might have 100s of .c files so you have to tell the system what you want the output to be.

    If you want to create a standard C++ class, create a new project that is a tool which is a C++ file. There's descriptions there. There's also the XCode manual that you can refer to which basically tells you which project to choose.

    It's complex-looking at first, but XCode isn't that hard to use after awhile.

    It's a great IDE, and this is coming from MinGW on the Windows platform.

    I'm sorry, can you be more specific? I am using Xcode 3.1 if that is any consolation. :)

    I highly recommend Aaron Hillegass's book Cocoa Programming for Mac OS X to learn how to use XCode and how to develop Mac applications.
