LLDB supports command completion for source file names, symbol names, file names, and so forth. To demonstrate it, you should execute the command and examine the help system results: Arguments to a command that are specified in the help output in angle brackets (such as
Enter break x, where x is the line of the first cout statement in the main() method. âbreakpoint listâ, and we report the breakpoint as âpendingâ when you set it so by lldb in interactive debugging. The LLVM C++ compiler, clang, has an accompanying debugger: lldb. First we need to set the program to debug. conditions or commands without having to specify them multiple times: Setting breakpoints by name is even more specialized in LLDB as you can specify When you are satisfied that the input is working, you can continue (or c), and the program will run until the next breakpoint, or the end of the program. and then begin an lldb session to debug it, as follows: Typing run will run the lldb_tut program.
that thread, do: You can also provide a list of threads to backtrace, or the keyword âallâ to see all threads: You can select the current thread, which will be used by default in all the If this program is compiled (remember to compile it with -g) and run through the debugger, it will crash, and the resulting stack trace looks like the following: The frames are listed on the left-hand side, and you are in frame #0 by default (it states this in some of the lldb output that was not included above).
Important: One alias included by popular demand is a weak emulation of the GDB break command. The step command steps into that function; in other words, you see the debugging session move into the called function. command set. The down command moves you back down a frame towards where you started. bitter experience, the more thorny one's problem is, and the more
If you call âframe variableâ passing in the names of a So when you run the debugger, you specify the executable file (not the source file) as the input to the debugger. It will show you one screen of output. In this case, to learn more about
commands are more verbose but also more precise and allow for intelligent auto stylesheet based on. While paused, we can find out where we are in the program, what values variables have, reset the values of variables, etc. Enter n (or next) – this steps OVER the next command. All the features of the debugger are available as classes in the Python interpreter.

The principles and commands described in this document are specific to the lldb debuggers for clang++ under UNIX, but every debugger has similar commands. Both are useful, depending on what level of detail you need. the original code, fix the problem, remove all the debugging messages Remember to put your identifying information at the top. If you see that a variable has the wrong value, and you’d like to change that value in mid-stream before continuing execution, you can do this easily. resolve to one or more locations. commands still can have options, if your command string has dashes in it, lldb also has a built-in Python interpreter, which is accessible by the
The up and down commands let you move up and down the calling stack (of nested function calls) so you can issue debug commands about the function that’s “active” at each level. tool well. You can then examine the contents of the variables in that frame before moving on. Individual options in a
