Lazarus debugger fail in Ubuntu 13.04

[miguel-laz]

Just installed Lazarus 1.0.8 on Ubuntu 13.04 (64bit) and trying to debug a simple program, the debugger stops at the breakpoint marked but when you stop debugging (red square button) displays a debugger error window indicating "The debugger entered into a failed state." In windows7 32bit works perfectly.

This is the simple program:

Code: [Select]

unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls;

type

  { TForm1 }

  TForm1 = class(TForm)
    Edit1: TEdit;
    procedure Edit1Enter(Sender: TObject);
  private
    { private declarations }
  public
    { public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.lfm}

{ TForm1 }

procedure TForm1.Edit1Enter(Sender: TObject);
var str:string;
begin
     str:='Un texto';
     TEdit(Sender).Text:=str;
end;

end.

The breaking point is on the line that says "str:='Un texto';":

The version of gdb is GNU gdb (GDB) 7.5.91.20130417-cvs-ubuntu

Has anyone tried Lazarus on Ubuntu 13.04 (64bit)?
Can anyone reproduce the error?

Thanks in advance

Can you try to produce a log and attach it:

[marcov]

Btw, gdb 7.6 came out in recent days. Listed some MII improvements.

As the text exceeds 20000 characters the whole message is in the attachment:

OK, The following text corresponds to the output of the debugger until the breakpoint corresponding to the line "str:='Un texto';":

The first error message says something like:
^error,msg="No hay tabla de s\303\255mbolos cargada. Use la orden \302\253file\302\273."

which in English means something like:
^error,msg="No symbol table loaded. Use the command?. ".

[Martin_fr]

Yes, but IIRC that error msg can occur.

I will need the entire log file.

Also, I see that you use a translated gdb (not English). I have see similar cases, and some messages that the IDE looks for in English, are also translated. Then the IDE can not work with that gdb.

I've been using Lazarus since v9.3 on Ubuntu without problems until I upgraded to Ubuntu 13.04 (32-bit) on the weekend and now I get this problem too

[Martin_fr]

Again: log file please.

Lazarus is currently tested with gdb (english) from 6.3 to 7.5
I will hopefully be able to test tests for 7.6 soon But I don't know how soon.

GDB 7.6 (even english) may have changes, in the response output of some commands. Then the IDE does not understand it.

In addition. If gdb is translated, it may or may not work. I have seen translated gdb working, because the IDE used fallbacks, if it got replies that it could not read (and luckily the fallbacks had enough keywords to be understood). But beeing already forced to fallbacks makes it more likely to fail on other changes.

[macmike]

I'm using the English versions. Where can I find the log file?
(sorry for the dumb question!)

[Martin_fr]

Sorry, I dint see the attachment on the post earlier. reading that now

Just installed Lazarus 1.0.8 on Ubuntu 13.04 (64bit) and trying to debug a simple program, the debugger stops at the breakpoint marked but when you stop debugging (red square button) displays a debugger error window indicating "The debugger entered into a failed state." In windows7 32bit works perfectly.

Ok, I went to through the log file (from the attachment. It looks like everithing went correct.

When you stop (rud square) then the app is killed.
The IDE verifies that the app really is killed, by sending "info program"

An English gdb will reply with a phrase containing "not being run" (as the program is not being run), and the IDE checks for this text.
Your gdb responds  (as you actually pointed out correct)

Code: [Select]

&"info program\n"
~"El programa que ha sido depurado no estaba corriendo.\n"

The IDE does not understand this, and assumes something went wrong.

Maybe this message was not translated in previous versions of gdb. (you will notice, that some messages by your gdb are still English)

---
Another thing I spotted is, that the response to "info file" is not English.

This does not cause an error right away. But it does mean, that the IDE may not show you the type and msg of an "raise exception"

I know this problem also exists in older gdb, if they are translated.

----
and

""[Nuevo Thread 0x7fffecaf9700"

may mean that your thread window does not always update

[Martin_fr]

I've been using Lazarus since v9.3 on Ubuntu without problems until I upgraded to Ubuntu 13.04 (32-bit) on the weekend and now I get this problem too

If yours is not translated, then there must be yet another issue. It is possible the gdb team changed some of the english messages too.
