I did this literally as you wrote. So my Package options Object box
contains the text $(PkgDir)

It does not work, Lazarus does not find the obj file anyway.

So next I tried:
$(PkgDir)\..\Sentinel

This time it passed the previous error only to arrive at:

lazarus.pp(161,1) Error: Illegal COFF Magic while reading
D:\Engineering\Projects\Subversion\EI\CMPFPC\Sentinel\SPROMEPS.OBJ

Does this mean that the OBJ file that has worked for more than 15
yesra on different versions of Delphi is somehow of a format not
acceptable by Lazarus?

What is COFF Magic?
