Cool.

Thanks for the help.

To change the application type to GUI I used Project->Properties...->Build Targets tab.  I then selected "GUI application" in the Type: dropdown box.

I noticed I also had to go to Settings->Compiler and debugger...  Then I selected the "Debugger settings" on the left panel and checked the "Display debugger's log" check box.

A "Debugger (debug)" tab appeared at the bottom of the workspace and my output appeared there.

It also looks like I can keep using a terminal and simply ignore the warning as suggested by jens.  I have noticed, however, that my application doesn't exit debug mode quite the same as it does when I do a normal "Run."  When I run the program (simple Hello World) as a console application through the "Run" command, I get the message, "Press ENTER to continue."  After you hit enter the terminal window closes.  When I run the application using "Debug / Continue", the console appears, my output flashes on the screen, and the console quickly closes without the previous prompt.  Its probably worth mentioning that I have checked the "Pause when execution ends" check box under Projects->Properties->Build targets tab

I'm not sure if that is a bug or not.  Does Code::Blocks open and close the console or does gdb?  In any event the "problem" is easy enough to deal with by simply setting a breakpoint on the return call in main().

I'm using Code::Blocks 8.02 on Ubuntu 9.10 with gdb 7.0.

Thanks again for the help.

BTW... I'm just getting back into programming after a ~10 year hiatus.  I've tried a couple of the other linux open source based IDEs including KDevelop, Anjuta and Eclipse.  So far Code::Blocks has been the easiest to get up and running.  Thanks for the cool app.
