COS 126: Mac OS X Installation Page

This documents instructs you on how to setup a C programming environment for your Macintosh computer. The instructions will deal with configuring one of the laptops purchased through SCI, although if you bought your own equipment you should be able to adapt the instructions below. All of the software below is either shipped with your SCI computer or can be downloaded from the Web.

• Upgrade to OS X 10.2 if for some reason you are still using OS 9. We recommend at least 10.1.

• Open a terminal window. You can find this under Go -> Applications -> Utilities. Drag the Terminal to your dock since you will be using it frequently.

• You should now have a "Terminal" window somewhere on the screen. It will have a command prompt that looks something like:

  [localhost:~] wayne% 

  You can enter a command by typing it in the Terminal window followed by the "Enter" or "Return" key.
• For your first command, type the text in bold at the command prompt:

  [localhost:~] wayne% pico .tcshrc

  Now, type in the following text and save the file with Ctrl-o.

  setenv PATH ${PATH}:.
  alias gcc126 'cc -ansi -Wall -W -O'
  

  You probably won't be using the pico editor very often, but it's sometimes useful. (This adds the current directory to your path and tells the compiler to allow only legal ANSI C programs. If this sounds like gibberish, don't worry about it.)

• Now, close the Shell window - the customizations will take effect the next time you open a Shell window.

The Developer Tools include a C compiler, debugger, and lots of other goodies. It should be pre-installed on all recent Apple machines. To see if it is installed on our machine, go to the Terminal and type

which cc

We recommend using Project Builder and adding it to your dock. It is included with the Developer Tools. On my system, you can find it from the Finder via Computer -> OS X Partition -> Developer -> Applications -> Project Builder.

BBEdit is another popular text editor for the Mac. The "Lite" version is freeware. It can be downloaded from www.bbedit.com.

MacGSView is a program that allows you to view PostScript files. You will need such a program when we create graphics, starting in Assignment 2.

• Download and install the PostScript viewer MacGSView for OS X from www.cs.wisc.edu/~ghost. OK, it looks like they took down the OS X version. Instead, download the MacGSView for OS X Preview here.

• Or, you can download the PostScript viewer MacGhostView. Unless you've already installed ghostscript, you want to download MacGhostView (and not MacGhostViewX).

Acrobat Reader allows you to view pdf files. Many of the documents on our Web site are in this format. If you bought your computer from SCI, you probably have the OS 9 version of Acrobat installed. We recommend upgrading to the OS X version.

• Download and install the pdf viewer Acrobat Reader for OS X from www.adobe.com.

Fetch is an FTP client that allows you to transfer files to and from your computer. On many assignments we provide various sample code and data files which you will probably want to download.

• If you bought an SCI computer, you probably already have it installed. Otherwise, you can download it from from CIT's site.

Nifty telnet is a telnet and ssh client that allows you to login to a remote system such as arizona. If you plan to edit and compiler programs under OS X, you may not need this program.

• If you bought an SCI computer, you probably already have it installed. Otherwise, you can download it from from CIT's site.

Some of the in-class demos are in PowerPoint format.

• If you have MS Office, you don't need the viewer. Otherwise, you can download a free PowerPoint viewer from Microsoft.

It is automatically installed along with OS X.
