Hi,

I am trying to debug an application on my old ppc mac running macosx 10.4.11 with lazarus from trunc. On debugging the app starts, but it does not accept breakpoints... The console-output is the following:

[TCmdLineDebugger] Debug PID: 14010
TGDBMIDebugger.ProcessResult Error: ,msg="No symbol table is loaded. Use the \"file\" command." [Debugger] Running GDB version: Apple version gdb-437 [TDebugger.SetFileName] ""
[TMainIDE.DoRunProject] B TGDBMIDebugger
TGDBMIDebugger.StartDebugging WorkingDir=""
TGDBMIDebugger.ProcessResult Error: ,msg="No symbol \"FPC_THREADVAR_RELOCATE_PROC\" in current context." [Debugger] Log output: &"info functions FPC_CPUINIT\n" [Debugger] Log output: &"info address main\n"
[Debugger] Log output: &"info file\n"
[Debugger] File type: mach-o-be
[Debugger] Entry point: $00002770
[WARNING] Debugger: Unexpected async-record: =shlibs-updated [Debugger] Target PID: 14014
[Debugger] Log output: &"No source file named unit1.pas.\n" TGDBMIDebugger.ProcessResult Error: ,msg="No source file named unit1.pas." TGDBMIDebugger.ProcessResult Error: ,msg="mi_cmd_symbol_list_lines: Unknown source file name."

Yes, I have a unit1.pas :-) although it is named Unit1.pas - but is macosx not case insensitive by default anyway? Is my gdb just too old?

This message seems showing that no debug information was found in the executable file:

TGDBMIDebugger.ProcessResult Error: ,msg="No symbol table is loaded. Use the \"file\" command."

I'm not used to anything different than windows, but had you checked that you are writting GDB information ?

Hi JoshyFun,

yes, I am writeing debug information. I tried:
-g
-Xg
and both with no success

the output send earlier was made using both options.

-Xg can only work with DWARF on Mac OS X. Either use -gw -Xg or plain - g without -Xg.

Hi Jonas,

if I use plain -g I get:
[TCmdLineDebugger] Debug PID: 15860
TGDBMIDebugger.ProcessResult Error: ,msg="No symbol table is loaded. Use the \"file\" command." [Debugger] Running GDB version: Apple version gdb-437 [TDebugger.SetFileName] ""
[TMainIDE.DoRunProject] B TGDBMIDebugger
TGDBMIDebugger.StartDebugging WorkingDir=""
TGDBMIDebugger.ProcessResult Error: ,msg="No symbol \"FPC_THREADVAR_RELOCATE_PROC\" in current context." [Debugger] Log output: &"info functions FPC_CPUINIT\n" [Debugger] Log output: &"info address main\n"
[Debugger] Log output: &"info file\n"
[Debugger] File type: mach-o-be
[Debugger] Entry point: $000023b0
[WARNING] Debugger: Unexpected async-record: =shlibs-updated

and if I hit a button on my simple app, the app hangs and I do not get to the break-point of the button on-click event (and no more output on console)

Does the directory yourapp.dSYM still exist? (this is what gets generated when you use -Xg) If so, delete it.
