Hi guys...
I tried to debug my new Lazarus Project but failed baldy (linux -
Lazarus 0.9.6).
When i try to set breakpoints I only get these questionmarks and it
doesn't work. (win32 works perfect - but I would prefer linux)
My question: is it possible to get the Lazaruz-IDE debugging my
project ? Are there any hidden switches which must be turned on ?
Thanks in advance...

On Linux:
Did you define a debugger (and a correct path) ?
And what version of gdb are you using ?

I don't know of hidden switches. Debugging usually works better on
linux than on win32. It is possible to debug your project on linux
with Lazarus.

I have the same problem, but when i click on the bottom, i can't press
F7 or F8, and i don't see the variable value.
Why?

this is my procedure and I Have a breakpoint on the for

procedure TForm1.Button1Click(Sender: TObject);
var
   i,t : word;
begin
   t := 1;
   for i := 1 to 10 do begin   ////BREAKPOINT
       t := t * i;
   end;
   Label1.Caption:= IntToStr(t);
end; 

when I press the button I get in the source code but I don't see the
variables values (in my case t and i) I moved the mouse on the i and t
but nothing.

WHY?

Sorry for my english

You expect a hint showing the value of the variable when you move the
mouse over the variable? I do not think it is implemented (yet).

----------------------------------------------------------------------

This is implemented
You have to turn it on in: Environment - Editor options, Code tools
tab, Tooltip expression evaluation

That chech is checked :?  But I don't see the Hints with the value of
variable

1) while debugging, do you see some output in the view debugger output
window ?
2) if you use evalueate expression, dou you get a value

BTW, you only can see values when the debugger is paused (you hit a
breakpoint)

Where?
On windows(XP SP2) and lazarus(snapshot from 23dec2005 to now). I
check "use evalueate expression" i set breakpoint. in "Watch list" i
see needed value. but no hints.
(same on linux ASPLinux)
??????????
