I remember seeing something like that a while back, but I think it only worked under Win32 platform. A quick look in the Lazarus directory I also see "/debugger/fpd/" which seems to be the start of a Object Pascal based debugger.

Like Graeme, the thing I miss most in FPC/Lazarus is the debugger I'm used to from Delphi. At the moment I'm helping myself with Log-Files, but that's far more complicated to use to hunt down a bug in a larger project Regards Lukas -- -- software security networks Lukas Gradl Eduard-Bodem-Gasse 9 A - 6020 Innsbruck Tel: +43-512-214040-0 Fax: +43-512-214040-21 -- ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

This is exactly the errors I get. I develop under Linux only, so it doesn't seem to be a platform issue. I gave up trying the integrated debugger and simply use Log(..) or Writeln(...) calls now.

Is there no way we > can hook (tie in) the Kylix or Delphi debugger into Lazarus? Which debugger for what platform? IMO the integration of the GNU/FPC debugger is the only way to cover all platforms at once. I cannot sort out what's FreePascal and what's Lazarus specific with debugger problems. But I wonder about random popups from the debugger at start of my applications - it looks like uninitialized variables to me, somewhere in the LCL/RTL?

What do you do different to me then. I also use Linux. Most of the
times, break points don't trigger, tooltip on identifiers don't work,
selected code with tooltip evaluation never works, variable watches
never work etc
Thank goodness 99% of my applications are tiOPF based, so I use the
tiLog unit to log debug information to a file, console or separate log
window. And for those non-tiOPF based apps, I'm stuck with:
writeln('>> SomeProcname');
code goes here
writeln('variable = ', somevariable);
code goes here
writeln('<< SomeProcname');
PS:
Yes I know toolip evaluation or tooltip debugging over properties etc
are dangerous, but it's a damn sight better than not having it. Plus
the Delphi developers are perfectly happy with the way it works for
them.

Yeah, that is one thing I seriously miss about Delphi and Kylix (thought not nearly enough to make me switch back). Is there no way we can hook (tie in) the Kylix or Delphi debugger into Lazarus?

[Lazarus] Debugger problems
Hello List I am having trouble trying to debug any application from Lazarus. Any pointers to what could be wrong. Lazarus is running on a Windows XP (SP2) box. The application is a newly created project. and I get the error : "Project raised exception class 'External:SIGSEGV' ". When I click on the message box Lazarus shows another window (Backtrace - I think) and dies. When I restart - the main IDE window position has been changed and is hardly visible at the bottom of the screen. I am using Date: 2009-02-05 FPC Version: 2.2.3 SVN Revision: 18572 Any pointers on how to get the debugger going? Regards Alex du Plessis ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
