I think 'print' is underrated as a debugging tool, particularly when you don't know what to look for. You can at least start zeroing in on the line where things fall down, go boom.

That said, I use gdb a lot lately, since my new job at work is getting some existing C code up to snuff for a new FDA-mandated standard.

Still, I love the debugger in XCode on OS X. It's like most things you get from Apple. You think it's nice, but when you use other similar tools, you really appreciate just how good it is.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
