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:
*$ sdcc -V -mpic16 -p18f4550 -c delay.c*
+ "/usr/local/bin/sdcpp" -nostdinc -Wall -Dpic18f4550 -D__18f4550
-D__SDCC_PIC18F4550 -DSTACK_MODEL_SMALL -D__STACK_MODEL_SMALL -obj-ext=.o

-D__SDCC_pic16 -DSDCC_pic16 -D__pic16 -D__STDC_NO_COMPLEX__

"/usr/local/share/sdcc/include" "delay.c"
+ "gpasm" -DSTACK_MODEL_SMALL -D__STACK_MODEL_SMALL -o "delay.o" -c
"delay.asm"
And
sdcclib libmydelay.lib delay.o
$ sdcclib -s libmydelay.lib delay.rel:
And I have gotten the same error again: * *error: "libmydelay.lib" is not a
valid coff object or archive
returned errorcode 256
