Error when debug lazarus / 12-Debugger ---------------------------------------------------------------------- berocoder · 2019-03-01 22:04 I have many years of experience from Delphi and now I also tried Lazarus and FPC om my MacBook with OSX 10.13.6 High Sierra. I installed Lazarus 2.0.0 and FPC 3.0.4. I could compile and run programs. But when I debug them these two dialogs is shown. 1. Initialization output: Error: file specified in --source (-s) option doesn't exists: 'ilent' 2. -gdb -set confirm off did not return any result Any hints what I can do ? ---------------------------------------------------------------------- Martin_fr · 2019-03-02 04:35 First of all, what are your settings under: Tools > Options > Debugger "debugger type and path" (dropdown and edit)? Is your Lazarus a new install, or an update? While gdb can be used as debugger (if you actually build and signed gdb), it is not the recommended one. The recommended settings are: "lldb (with fpdebug)" for the drop down /usr/bin/lldb   for the edit field ---------------------------------------------------------------------- berocoder · 2019-03-02 10:29 Hi and thanks for the answer. It works now. Path was correct but debugger was gdb. When change to lldb it works.
