Quite a few people have written to me about issues they have with C++ All-In-One Desk Reference For Dummies that involve getting CodeBlocks up and running. The posts in the C++ All-in-One for Dummies archive normally provide everything needed to get the compiler up and running. I even provide posts on using the 10.05 version of the product, should you wish to upgrade. However, there are rare times when no matter how much you try, you simply can’t get the compiler to work.
One technique I haven’t really covered until now is to reset the CodeBlocks configuration. The problem with this approach is that it resets all of your settings, not just those that could be in error. This is the reason that I’ve taken a more measured approach to helping readers through problems until now. My concern is that resetting everything will actually cause more problems and end up confusing some readers, so you really do want to try those other posts first. That said, there are situations where resetting CodeBlocks is the only course of action that will work.
To reset your settings, open your copy of CodeBlocks. Choose Settings | Compiler and Debugger. You see the Compiler and Debugger Settings dialog box shown here.
Click Reset Defaults. This action will reset all of the defaults so that they match the initial installation configuration unless you have created a default of your own. Make absolutely certain that the Selected Compiler field shows GNU GCC Compiler as shown in the figure and then click OK. Close and then reopen CodeBlocks before you test your configuration.
Let me know if you have any questions about this procedure at John@JohnMuellerBooks.com. It’s always my goal to make my books as useful to you as possible.
