Which object? Better show the code.

The 1st thing that comes to mind is that spromeps.obj is 32 bit and your 
Lazarus/fpc and Windows are most probably 64 bit. But I am not sure how 
the compiler/linker would react to that.

You had posted previously:
Input file: SPROMEPS.obj, output file: SPROMEPS.coff
Converting from OMF32 to COFF32 <--------------------------------

Do you have a 64 bit version of spromeps.obj?
