Yes, because MMO is not a linkable format. The GNU assembler
produces objects that must be further processed by the linker,
unlike for example nasm (for flat binary .COM) and mmixal. I
have to ask - do you know what these formats are (as opposed to
e.g. trying to see what object formats can be produced)?
Knowing what you try to achieve might help improving the

It's admittedly a bit unclear in the ld documentation that
"emulation" can mean "output format" (one might be tempted to
use "-b", but that'd be wrong), but I think the rest of the

the linker documentation over clarifying it on a mailing list,
so please have a look and tell the first question that comes to
