GDB

│ English (en) │ français (fr) │ polski (pl) │

GDB, abbreviated for GNU debugger and named gdb as an executable file, is the standard debugger for the GNU operating system and many other platforms including Linux and Windows. In macOS 10.14 (2018) and FreeBSD 13.0 (2021), gdb was replaced by lldb, and is no longer supported. Lazarus uses GDB as the default debugger.

GDB is not a part of Lazarus. Unless you are using Windows or certain versions of macOS with Xcode, you have to install it yourself before using it. Earlier versions of Xcode come with bundled GDB. After installation it will be necessary to set the path to gdb (for example /usr/bin/gdb) in Lazarus' debugger settings.
