Hi all,

Basically I want to get a stack trace and log it when a special exception occurs. All I could find about was the lineinfo.pas (and -gl switch) but that does not help much as it interfaces only one procedure which is no good for client usage. What do I miss; what common things do you use for your own exception logging&handling?

Actually the ultimate solution would be having something like the infamous Madexcept or EurokaLog Delphi addins. Are there any similar attemps I overlooked?

It seems I will be using more and more FPC on my job and I am addicted to such tools which makes me mad when I need to debug for some crash just to get a callstack :) So, before I start rolling a solution, what are your advices and where should my efforts go so that the community would also benefit?

I don't know those tools, may Multilog does something similar: http://wiki.lazarus.freepascal.org/MultiLog

There's

Procedure Dump_Stack(var f : text;bp:pointer);

in the system unit. You can use it like this:

   dump_stack(stdout,get_frame);

to dump the current call stack to standard output (or to any other text file by replacing stdout with something else).

Yes. It has a specialized SendCallStack function.

BTW: I will update it shortly

This cleared a lot on my mind, thanks Jonas...

Recently I have tried this:
//------------------------------------------------------
try
    AFunctionThatWillRaiseAnExceptionDeepInside;
except
    Dump_Stack(stdout, ExceptAddr);
end;
//------------------------------------------------------

Unfortunately this did not do what I thought: giving the callstack from the point of where exception occured. Is there any way for that?

Thanks,

Multilog also provides a SendException method that will give the exception stack frame along other info
