	For ~~the statgen library~~, you can compile with: <code>make ~~OPTFLAG="-ggdb -O0"~~</code>		For programs using libStatGen, you can compile with: <code>make debug</code>, which will generate a debug executable in bin/debug/

	Do not specify command line options at this point. That will be done later when you type [[Debuggers#Run with options\|"run"]]		Do not specify command line options at this point. That will be done later when you type [[Debuggers#Run with options\|"run"]]

== Advantages/Disadvantages ==
* Advantages
** Single step through the code
** Stop execution at a given point to investigate where it goes and what the values are
** Attach to an already running program
* Disadvantages
** Not running real-time, so may not expose all problems
