Template:Debugger Backend List

GNU Debugger (gdb)

The first debugger that was supplied with Lazarus. This debugger uses GDB as backend. The IDE performs translations between gdb's none Pascal-ish interface and the interface provided by the IDE. Package: LazDebuggerGdbmi

GNU Debugger through SSH (gdb)

Allows to launch GDB over an ssh connection for remote debugging. This has however some serious limitations. Package: LazDebuggerGdbmi

GNU remote debugger (gdbserver)

Remote debugger using GdbServer (part of the gdb suite). Package: LazDebuggerGdbmi

LLDB Debugger (Alpha)

A basic LLDB based backend. This is a prove of concept implementation. The IDE displays raw LLDB output (no translation, no clean-up...) and there are no plans to add translation of the LLDB output. For using LLDB on Pascal applications the "LLDB Debugger (with fpdebug)" should be used. Package: LazDebuggerLldb

LLDB Debugger (with fpdebug)

This debugger uses LLDB as a backend. In order to display Pascal-style results, it uses the "fpdebug" engine to show locals/watches. LLDB is used to control stepping, breakpoint and execution. For reading data LLDB is used to read the raw memory only. Package: LazDebuggerFPLldb

GNU Debugger (with fpdebug)

Using GDB for stepping/breakpoints/... and FpDebug for watches. Package: LazDebuggerFPGdbmi

FpDebug / LazDebuggerFp - integrated DWARF debugger / (Known issues)

A new debugger completely implemented in Pascal. This debugger implements the DWARF standard (currently 2 and 3 are partly implemented). It has special implementations added to interpret info provided by FPC. It can currently be used on Windows and Linux (very basic support for MacOS). Package: LazDebuggerFP

FpDebug / LazDebuggerFpRspRemote

A new remote debugger to communicate with a gdbserver stub using gdb's remote serial protocol over tcp/ip (in future this could be expanded to include serial/UART). This debugger inherits from LazDebuggerFP, hence in principle supports the same functionality. Currently it only supports the AVR target. Not stable yet. Package: LazDebuggerFpRspRemote

DAB / LazDABDebugger

The Debug Adapter Protocol (DAB) is a protocol to abstract the communication between a Debugger-frontend like Lazarus, and an underlying debugger like FpdServer. LazDABDebugger is a debugger that connects to (any?) DAB-adapter. This makes is possible to debug other languages or different platforms within Lazarus.

DAB - FpdServer / LazFPDServerDebugger

A derivative of LazDABDebugger specifically shaped to work with FpdServer, a debugger based on FpDebug that supports the DAB-protocol.
