Would anybody be able to enlighten me on enabling exception trapping in Linux libraries ?

As far as I can tell, exceptions propagate through to the main app - (written with Lazarus in this case).
I would like to trap them directly within the library.

Pointers, clues, links, examples (heck, even full source) really appreciated :)

Thanks - SteveG

// excp.pas
library excp;
{$mode objfpc}
uses sysutils;
procedure p;
begin
  try
    raise exception.create('an exception')
  except
    on e: exception do
      writeln(e.message);
  end;
end;
exports p;
end.
// test.pas
procedure p; external 'excp';

begin p end.

run with:
$ LD_LIBRARY_PATH=. ./test

you should get:
an exception

tested on ManjaroLinux 64-bit.

Tested this, and you are correct - it captures it correctly After further testing - It would seem to capture some but not others ?

(contrived example - I know not to directly call a control within a library) this doesnt seem to be trapped - drops thru to main app

   try
     Str1 := TControl(0).Name;
   except
     on e: exception do
       writeln(e.message);
   end;

Would this suggest a different signal attachment is necessary ?

Thanks
