You are using wrong tool to create the pic library: you should use the
gplib librarian which is a part of gputils.

Thanks Borut Ražem and Douglas Goodall for the advices.
I think sdcc compiles by default for the 8051 core and the sdcclib
only accepts *.rel files and not *.o files.
I have tried:

Probably better to name the library something other than the name
of the routine, like mydelay.lib.
Instead of putting delay.lib in the object list, you could try
"sdcc ... -l mydelay"
Good luck,

I know the sdcc has already a delay library but, I would like to
learn how to create libraries.
I don't understand what is a ''valid coff object or archive '
and why the this error happens. I also would like to know how to
create libraries like the native library of the SDCC like libc18f.
