config.bfd with binary?

[kubeos]

Does anyone know what I should put for my default vector in config.bfd?

My executable format is binary. I've tried bfd_binary_vec and binary_vec and it doesn't recognize those. I might have to use aout or something for now and just use a linker script to make my apps compile to binary format.

Thanks in advance.

Actually, I suppose it would be easier to just use binary as my target when doing a cross compiler.

But still.. i586-binary doesn't work. Anyway, I'll keep looking, because I really don't want to do elf.

[EDIT] Okay, I did use i586-elf as my target and just fixed the default linker script to output "binary" with a text address of 0x0. Everything worked out that way. Now I just need to get newlib ported.

Why not?

By default, every libbfd compiled should contain support for
the binary output format, as well as srec, symbolsrec, tekhex and ihex. I think what you're trying to do is set the default emulation for ld, which is specified in ld/configure.tgt. You probably need to create your own emulation, but can use the elf scripts, e.g.

emulparams/binary.sh:

Code: Select all

SCRIPT_NAME=elf
OUTPUT_FORMAT="binary"
TEXT_START_ADDR=0
MAXPAGESIZE="CONSTANT (MAXPAGESIZE)"
COMMONPAGESIZE="CONSTANT (COMMONPAGESIZE)"
ARCH=i386
MACHINE=
NOP=0x90909090
TEMPLATE_NAME=elf32
GENERATE_SHLIB_SCRIPT=no
GENERATE_PIE_SCRIPT=no

although this is entirely untested. Using it the way you are doing is as good as, however.
