Hi,

Why is Lazarus ignoring my breakpoint? If I put a writeln() statement before line 1466, it is executed and I see console output. So that code is definitely being run. Yet Lazarus think it isn't and simply ignores the breakpoint - for no reason. See attached screenshot.

I'm using FPC 2.2.5, Lazarus 0.9.27 r19685 and GNU gdb 6.8-debian under Ubuntu Linux 9.04.

Regards,
- Graeme -

I place the following writeln() statement before line 1466 and below is some sample output, showing the writeln() is being run.

   writeln('******************************************');

The color of the breakpoint seems to indicate there is no line info for that unit. Can you attach the debug output (maybe zipped) (View -> Debug Windows -> Debug Output).

While it is not the answer to your question, I had a similar issue and found, that breakpoints only worked, if they here set *before* I started the application to debug. (This was on FreeBSD)

Maybe worth trying until the issue is fixed?

This is what I have done. Set the breakpoints, then run the application through the IDE. The IDE then outputs to the debug xterm console.

that unit. Can you attach the debug output (maybe zipped) (View -> Debug Windows -> Debug Output).

Umm, another new window I didn't know about. :-)

The output has been attached as an archive. The most interesting bit is probably the last few lines which looks like this. I guess that is the problem - though I have no clue how to fix it.

===================================
(gdb)

<-symbol-list-lines
/home/graemeg/programming/3rdParty/tiOPF2/Source/UnitTests/Tests/tiObject_TST.pas> &"mi_cmd_symbol_list_lines: Unknown source file name.\n"

(gdb)

<-symbol-list-lines tiObject_TST.pas>
&"mi_cmd_symbol_list_lines: Unknown source file name.\n"

^error,msg="mi_cmd_symbol_list_lines: Unknown source file name."

(gdb)

===================================

And for completeness, below is when FPC compiler parameters that Lazarus IDE generates:

-MObjFPC -O1 -gl -vewnhi -l -Fi../../Core/ -Fu../Common/ -Fu../Tests/ -Fu../../Compilers/FPC/lib/i386-linux/
-Fu../../../../../../../../opt/lazarus/packager/units/i386-linux/ -Fu. -vm5024 -otextrunner -FU_Dcu

....or without relative paths....

And here is the directory layout as it is on my system. ===================================

Hope this helps!

You cannot debug console apps with lazarus. If you use an xterm as launching to see your console output, then gdb will debug the xterm and not your app. There is some patch to have a separate console, but I haven't reseached it yet.

Ah, that was it!! I switched to using the LCL based GUI version of the test suite and my breakpoint was working. Thanks for spotting the problem. :-)

Don't tested but, what about adding an Sleep at the start of the console app, then attach lazarus to your console process?.

FWIW, on windows there is no such problem, but I doubt that it incentive enough for you to reboot into windows.
