In your case delay.c is compiled for the default mcs51 target, since you
didn't specify -m and -p sdcc command line option.
Try with *sdcc -V ***-mpic16 -p18f4550* -c delay.c*.

I've attached the files used in this report.
I am using:

I am trying to create my own test library but I get this error:

I got : delay.rel
And then I do:
$ sdcclib delay.lib delay.rel
I got : delay.lib
$ sdcclib -s delay.lib

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.
