I'm trying to find a decent debugger for C with a GUI interface that allows me to do at least the usual stuff of setting break points, stepping over each line of code. I'm having a hard time finding one,(GDB command line didn't do good) and what's more, I'm on Ubuntu, not Windows, so I wonder if there is such a debugger.

Code::Blocks is a cross platform IDE which gives you a GUI wrapper to gdb, as well as providing a lot of development help - it is free, gratis & open source.

You can:

  • Set breakpoints
  • Step through the code
  • Inspect values
  • etc.

  • The problem with codeblocks' debugger is that it lets debug only on projects and not in empty files, and doing that always(making a project for each file to debug is a bit annoying), the problem is same for netbeans. VScode's debugger seemed descent but, I'm not being able to configure it for C(Some file open continuous errors)) Commented Nov 8, 2017 at 10:54
  • Plus, I couldn't find the column that tells us the variable values or the stack trace in codeblock. Commented Nov 8, 2017 at 10:55

    For your first issue you can attach to a running process see dummies.com/programming/cpp/… - if you tell it where the source code is then things go a lot easier. Commented Nov 8, 2017 at 17:26

    To inspect a given variable when you are at a break point hover over it in the source code, you can also right click and add to the watches on the right side of the screenshot. Commented Nov 8, 2017 at 17:28

Emacs provides a graphical interface to GDB, as well as other debuggers, through its Grand Unified Debugger (GUD) library.
