title: How to use GDB plugin in Geany?
body: <p>I have installed GDB plugin in Geany, which shows a tab as Debug. I am OK to use GDB in terminal, but cannot figure our a way using that Debug tab.</p>
  
  <p>Opening the tab, I can see several windows. I loaded an binary file into Target tab, then run it. Geany crashed immediately. In addition, most of buttons, such as step in, are in gray. Could not fine an online doc. </p>
  
  <p>Could anyone instruct me? </p>
