Does any one know if it possible to compile Exceptionerrorhandlig routine
(ExceptLog.PAs
from // http://www.jirihajek.net/delphi/ExceptLog.htm.

It seams to work fine with D7 but i'm not able to compile it wiht D5.
I allways receive this message:

[Error] ExceptLog.pas(138): Undeclared identifier: 'RTLUnwindProc'

Can You Help?

Thanks in advance
Mário

RTLUnwindProc is a normal pointer, it is initialized with the windows
API RTLUnwind.

interface

const
kernel = 'kernel32.dll';

var
RTLUnwindProc: Pointer;

implementation

procedure RtlUnwind; stdcall; external kernel name 'RtlUnwind';

initialization
RTLUnwindProc := @RTLUnwind;
end.

In D7, yes, but not in D5.

Yes, I know, that's why I gave the rest of the information :)

That download page specifically states that it was tested with D7 only.

RTLUnwindProc does not exist in D5. It was introduced in D6. That code
will not be able to function in D5 at all unless you re-write it to hook the
imported RtlUnwind() function directly.

Otherwise, I suggest you use another exception logger, such as MadExcept
(http://www.madexcept.com), which is known to work in many Delphi (and C++)
versions.

As I mentioned in my earlier reply, D5 simply does not offer the kind of
hooking that ExceptLog is trying to use. Just defining your own
RTLUnwindProc variable like Pieter suggested is not going to change that.
ExceptLog will not function properly in D5 unless you re-write it. So
either upgrade to D6+ in order to use ExceptLog, or else use a different
exception tracker that supports D5, such as MadExcept
(http://www.madexcept.com).

Mario,

sorry for confusing you, I didn't look how RTLUnwindProc is used in
Delphi and/or Exceptlog. Like Remy already said it's not going to work
by just adding the definitions.
